1. Field of the Invention
Enhancement of surfaces that may be permanently or temporarily re-designed, decorated, and/or re-colored is disclosed herein.
2. Description of the Background of the Invention
Improving the aesthetics in homes has long been practiced by many consumers. There is a plethora of home products and techniques for cleaning surface areas of soft surfaces such as carpets, rugs, draperies, curtains, upholstery, and the like. However, for more sullied and/or worn surfaces, subtractive processes (for example, a process that chemically or physically removes something from the carpet, such as cleaning or shaving) cannot truly restore the surface to its original state; this is often very frustrating for consumers. Oftentimes, spots and stains reappear after treatment.
Additive processes (for example, a process that layers, covers, or masks something undesirable underneath) and techniques for improving the aesthetics of surfaces include painting, faux painting, stenciling, bordering, wallpapering, tiling, wainscoting, paneling, decorative plastering, adding appliqus (for example, pictures, cut-outs, stickers, or the like), laminating, and molding (for example, crown, shoe, and chair) are also known. However, these products and techniques have not been applied to soft surfaces such as carpets, rugs, draperies, curtains, upholstery, and the like.
In some instances, color of worn, faded fabric is restored or rejuvenated with a composition containing water soluble and/or water dispersible polymers and a surfactant capable of forming a bilayer structure to provide a more durable color restoration and/or color rejuvenation benefit that lasts at least after one washing cycle, preferably at least after two or more washing cycles. The composition may be applied to the fabric by a spray container.
In other instances, a method of redyeing partially bleached fabric or garments includes dyeing the fabric or garment with a background color and then gathering an area to restrict access to further reagents. The gathered area is then bleached to remove the background colors from the area outside the gathered area and then the bleached areas are redyed with a second color.
In yet further instances, a digital printing device has a rotatable wheel, a liquid dispenser for depositing a liquid paint, ink, or dye on the wheel along an outer edge, and an air jet positioned adjacent the outer edge for removing the liquid from the outer edge and directing the liquid toward a print medium as the wheel rotates through the air jet. A plurality of devices is used to produce a full color digital image.
According to one aspect of the present disclosure, a composition includes about 0.01% to about 3% by weight of a foaming agent and about 3% to about 60% by weight of a solvent system including a glycol-based solvent and at least one supplemental component miscible with the glycol-based solvent and in an amount sufficient to increase the evaporation rate of the solvent system at standard temperature and pressure. The composition further includes an optional propellant including at least one of a pressurized gas or a hydrocarbon, greater than about 0.01% by weight of an anti-corrosive agent, and a liquid carrier.
According to another aspect of the present disclosure, a method for affixing a colorant to a surface includes applying an effective amount of a composition to a surface to affect a color change thereon. The composition includes a colorant, a surface-active agent, at least one of a polymer or a resin, and at least about 70 wt % of a liquid. The method further includes allowing the composition to substantially dry on the surface to form substantially dry particles greater than about 1 micron in size attached to the surface and applying a solubilizing agent that includes a glycol-based solvent to the particles to achieve a film of the polymer or resin affixed to the surface.
According to a further aspect of the present disclosure, a method for solubilizing a homogeneous particle includes applying a solvent system including a foaming agent, a glycol-based solvent, and at least one supplemental component miscible with the glycol-based solvent and capable of increasing the evaporation rate of the solvent system at standard temperature and pressure to a composition that includes a surface-active agent and homogeneous particles having a colorant and at least one of a polymer or a resin. The method further includes allowing the homogeneous particles to be contacted by the solvent system for a sufficient period of time necessary to soften the homogeneous particles.

The present disclosure is directed to compositions, methods, apparatuses, kits, and combinations, for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. While several specific embodiments are discussed herein, it is understood that the present disclosure is to be considered only as an exemplification of the principles of the invention, and it is not intended to limit the disclosure to the embodiments illustrated.
For example, a composition useful in the present disclosure includes a décor product that is formulated to be applied and affixed to a surface. As discussed more fully below, if desired, the décor product may be substantially removed from the surface before being affixed thereto. If a user desires to remove the décor product, the décor product is formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the décor product to the surface in a permanent or semi-permanent manner, the décor product may be affixed to the surface by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical. The décor product may also be utilized in the form of a kit or in conjunction with a design device, such as a stencil, to control the application of the décor product to create, for example, a pattern on the surface.
Any surface is contemplated to which the décor product may be applied and/or affixed, including, for example, soft surfaces such as carpets, rugs, draperies, curtains, upholstery, and the like. In addition, the décor product may be applied to hard surfaces as well, including, for example, wood, metal, ceramic, glass, a polymer, a hard floor tile, a painted surface, paper, masonry material, rock, a fiber/composite material, rubber, concrete, and the like. It is contemplated that the décor product may be applied to any prepared surface, including, for example, pre-dyed, post-dyed, pre-manufactured, and post-manufactured surfaces. Further, the décor product may be applied during the manufacturing process of a particular good or object that includes a surface in which the décor product may be applied. Surfaces to which the décor product may be applied and/or affixed may be substantially dry, substantially wet, moist, or humid depending on the particular décor product utilized. Further, a décor product of the present disclosure may be applied to a substantially flat, smooth, and/or level surface or any other surface including rough, bumpy, non-smooth, stepped, sloped, slanted, inclined, declined, and/or disturbed surfaces.
Examples of carpets to which the décor product may be applied and/or affixed include modular tiles and panels such as Milliken LEGATO®, Milliken TESSERAE®, INTERFACEFLORT™, Tandus/C&A floorcovering, and from manufacturers such as Mohawk Industries and Shaw Industries, Inc. Additional examples of carpets include broadloom carpets, cut pile (velvet/plush, Saxony, frieze, shag), loop pile (level loop, multi-level loop, and Berber), and cut and loop pile (random sheared and tip sheared) carpets. Additional examples of soft surfaces to which a décor product may be applied and/or affixed thereto include, for example, area rugs (hand woven or machine woven), draperies, curtains, upholstery, and cellulosic materials, among others. Constituent materials of candidate soft surfaces include, for example, natural fibers such as wool and cotton, or synthetic fibers such as nylon 6, nylon 6-6, polyester, polypropylene (olefin), and acrylic, among others.
Decor products of the present disclosure may be formulated, designed, produced, manufactured, applied, removed, and/or packaged by any formulaic, chemical, and/or physical preparation appropriate for the specific embodiment desired, as would only be limited by the inherent nature of the constituent ingredients. Illustrative formulations of the décor products include a solid that may be dissolved or dispersed in a liquid to make a liquid-based décor product, a liquid carrier, an emulsion, a suspension, a colloid, a sol, a dispersion, a solution, a gel, a paste, a foam, a powder, a spray, a tablet, a solid, a gas, a diluent such as water or other solvent, an aerosol, and combinations thereof. Examples of chemical preparations include polyester polymerizations, latex aggregation, chemical milling, and microencapsulization, and other methods known to those skilled in the art. Physical preparation may consist of physically grinding the décor product ingredients or other means known to those skilled in the art. Décor products may be either synthesized from a molecular route, in which polymer resin molecules incorporate colorants, dyes, and/or pigment particles at the molecular scale, such as in the method of manufacture used in chemically prepared toners, or the resin and pigment particles may be physically blended together and crushed to appropriate size by mechanical means known to those skilled in the art.
The décor product may be chosen based on any number of criteria, including, but not limited to the surface type, condition, and/or composition to which the décor product is applied and/or affixed thereto. Further criteria for choosing a décor product include desired lightfastness, color range, intensity, uniformity of colorant, and/or desired curative and/or fixation properties of the décor product. Additional choice factors include enhancement of the appearance and/or feel of the carpet or other surface, masking a stain (for example, by laying an area rug-type décor product), or value adding to a surface (for example, to extend the life of a carpet).
A décor product useful in the present disclosure may comprise any one or combination of a colorant that includes, for example, a coloring agent, a dye, an ink, a toner, a paint, a patch, a carpet glitter, a fluorescent material, a composite thermal transfer sheet, a particle, a coating, a pigment, a luminescent material, a microparticle, magnetically responsive particles, a virtual colorant which is not colored until activated, and/or a colorant with hybrid pigment molecules, an additive, and combinations thereof. Illustratively, a décor product composition contains a colorant in an amount of greater than about 0.01% or less than about 95%, or between about 0.01% to about 70%, or between about 0.03% to about 15%, or about 0.05% to about 10%, or between about 0.1% to about 5%, of the total weight of the décor product.
Any imaginable color of the décor product is contemplated in the present disclosure including, but not limited to cyan, yellow, magenta, black, green, orange, violet, blue, red, purple, white silver, gold, metallic, clear, neutral, or non-neutral, and any combination thereof. Color may be imparted to the décor product by combining varying amounts of monochromic décor product particles of different colors or by combining varying amounts of polychromic décor product particles having different colors. Further, a specific décor product color may be achieved by combining predetermined amounts of monochromic particles of different colors or by combining predetermined amounts of polychromic décor product particles of different colors. In this way, all imaginable colors may be incorporated into the décor product.
The décor product may also comprise a virtual colorant that is not apparently colored until activated and/or deactivated. As an example, phosphorous containing colorants may be incorporated into a décor product to add special effects via fluorescent properties. Further, virtual colorants may add special visual effects by altering the apparent décor appearance according to light intensity, light angle, angle of view, and/or illumination of the décor product. Such activation of the virtual colorant includes, for example, exposing a phosphorous containing virtual colorant to various wavelengths of light. As known to those skilled in the art, phosphor containing compounds luminesce or fluoresce when exposed to light. When exposed to visible light, phosphor gives off visible white light. Exposure of a phosphor containing virtual colorant to sunlight may also make whites appear brighter because the ultraviolet light in sunlight gives the appearance that the whites in the virtual colorant glow brighter than “normal” white. When exposed to black light from, for example, a substantially ultraviolet-A wavelength emitting light bulb, phosphorous containing compounds glow with a purple hue. Black light can be provided, for example, from a tube black light that is basically a fluorescent lamp with a modified phosphor coating. This modified coating absorbs harmful shortwave ultraviolet-B and ultraviolet-C wavelengths and emits ultraviolet-A wavelengths. The tube of the tube black light is black so as to block most visible light while emitting mostly long-wave ultraviolet-A wavelengths. Another useful type of black light includes black light provided from an incandescent black light bulb. The black light emitting incandescent black light bulb is similar to a normal household light bulb, but incorporates a filter that absorbs most visible light while emitting infrared and ultraviolet-A light.
In a further embodiment, décor products containing virtual colorants may serve as night lights, indicate routes from room to room, exit routes, and/or escape routes.
Any number of products may be used in the décor product to impart reversible coloring to a surface. Such products include, for example, dyes, toners, powder paints, inks, and combinations thereof. Examples of dyes that may be used include water-based dyes such as LIQUIDTAINT™ and VERSATINT® by Milliken Chemical Company. Examples of toners that may be used include reactive toners such as powder toners.

The one or more colorants and/or one or more additives may be in the same or different compartments. This microencapsulated décor product particle may, for example, provide advantages such as to lengthen the shelf-life of the décor product, enhance décor product compatibility with delivery systems, promote bonding of the décor product to the surface, promote removability of the décor product from surfaces before and/or after fixation, and/or promote thermal fixation of the décor product to a surface. Other benefits associated with encapsulation of compounds include, for example, timed release of compounds, and buffering systems, among others known to those skilled in the art, and are contemplated in the present disclosure. The compartmentalized and/or microencapsulated décor product particles may have multiple distinct regions of equal and/or differing sizes containing the same and/or differing substances, such as, for example, one or more solids, one or more liquids, one or more gases, and/or combinations thereof.

Another embodiment contemplated in the present disclosure may incorporate one or more surface-active (surfactant) agents, for example, emulsifiers. The use of surfactants in the décor product may promote colorant and/or filler wetting, as well as improve flow and leveling of the powder finish. In addition, surfactants promote substrate wet-out during the cure reaction, which improves adhesion and corrosion resistance of the décor product. The addition of surfactants may increase the gloss and distinctness of images of the cured décor product, as well. The addition of one or more surfactants may act to stabilize the décor product formulation, as well as to assist in suspending the particles of a décor product formulation and attaching the décor product to a surface. Surfactants useful in the present disclosure include ionic, nonionic, and/or cationic surfactants.

The décor product may include magnetically responsive microparticles with or without colorant. In this embodiment, the décor product may be applied using a static charge and/or magnetically directed force. As an example, iron oxide and/or other magnetic particles known to those in the art form a part of the formulation rendering the décor product magnetically responsive. The magnetically responsive property may be used for further placement onto the fiber and/or for enhanced removal from the fiber and/or to aid with aesthetic considerations such as creating designs and/or patterns.
Further, the décor product envisioned in the present disclosure may have additives designed to impart additional non-visual benefits such as fragrancing and aromatherapy.

Examples of interactive elements include mood lighting, sound (for example, music, indicative sound, or instructive sound), and scent (for example, fragrance emitters, deodorizers, and/or odiferous pet barriers only detectable by animals).
Illustratively, a formulation of a décor product, for example, an emulsion, contains on a weight to weight basis, at least one of: 1) a surface-active agent in an amount of greater than about 0.1%, or less than about 75%, or between about 0% to about 50%, or between about 0.001% to about 30%, or between about 0.01% to about 10%; or between about 0.1% to about 5%; 2) an adhesive agent in an amount of greater than about 0.1% or less than about 75%, or between about 0% to about 50%, or between about 0.001% to about 30%, or between about 0.01% to about 10%; or between about 0.1% to about 5%; 3) a colorant in an amount of greater than about 0.01% or less than about 95%, or between about 0.01% to about 70%, or between about 0.03% to about 15%, or about 0.05% to about 10%; or between about 0.1% to about 5%; 4) an additive in an amount of greater than about 0.1%, or less than about 75%, or between about 0% to about 50%, or between about 0.001% to about 30%, or between about 0.01% to about 10%; or between about 0.1% to about 5%; and 5) the balance water.
Further, a formulation of a décor product, for example, a rheology modifier-containing composition contains on a weight to weight basis, at least one of: 1) a thickener in an amount of from about 0.01% to about 1%, or from about 0.05% to about 0.7%, or from about 0.1% to about 0.5%, or from about 0.12% to about 0.3%; or about 0.7%, or about 0.5%, or about 0.3%, or about 0.15%, or about 0.1%; 2) a gum in an amount of from about 0.01% to about 1%, or from about 0.03% to about 0.3%, or from about 0.05% to about 0.1%, or about 0.5%, or about 0.3%, or about 0.15%, or about 0.07%, or about 0.05%; 3) a clay in an amount of from about 0.01% to about 5%, or from about 0.05% to about 3%, or from about 0.5% to about 2%, or from about 1% to about 1.5%; or about 3.5%, or about 2.5%, or about 1.75%, or about 1.16%, or about 1%; 4) a surfactant in an amount of from about 0.01% to about 5%, or from about 0.05% to about 4%, or from about 0.15% to about 3.5%, from about 0.07% to about 1.5%, or from about 0.1% to about 0.75%; or about 5%, or about 4%, or about 3%, or about 1.5%, or about 1%, or about 0.5%, or about 0.3%, or about 0.15%, or about 0.1%; 5) a humectant in an amount of from about 0% to about 2%, or from about 0.1% to about 1.75%, or from about 0.25% to about 1.5%, or from about 0.75% to about 1.25%; or about 1.75%, or about 1.5%, or about 1.25%, or about 1%, or about 0.75%; 6) one or more anticorrosive agents in an amount of from about 0.01% to about 3%, or from about 0.05% to about 2%, or from about 0.1% to about 1%, or from about 0.15% to about 0.5%; or about 0.35%, or about 0.15%, or about 0.1%; 7) a biocide in an amount of from about 0.01% to about 2%, or from about 0.02% to about 1%, or from about 0.1% to about 0.5%, or about 1.5%, or about 1.25%, or about 1%, or about 0.75%, or about 0.5%, or about 0.3%, or about 0.2%, or about 0.1%; 8) a colorant in an amount of from about 1% to about 50%, or from about 2% to about 25%, or from about 3% to about 10%, or about 50%, or about 30%, or about 25%, or about 15%, or about 8%, or about 6%, or about 5% or about 3%; or about 1%; and 9) the balance water.
Further, a rheology modifier containing composition may include a fluid matrix component including a rheology modifier and a multi-component suspension stabilizer. Fluid matrix components may be present in a range from about 0.3% to about 14% in the décor product. Further, the multi-component suspension stabilizer may include components such as acrylic acid copolymers and surfactants, among others.
A clear toner may also be included in a décor product composition of the present disclosure in an amount equivalent to, for example, the amount of the colorant. For example, in a toner formulation having 10% by weight a colorant, an additional 10% by weight of the toner formulation contains a clear toner. Illustratively, in a toner formulation with about 0.5% w/w yellow colorant, about 0.4% w/w magenta colorant, and about 0.2% blue colorant, the toner formulation also contains about 1.1% clear toner. In another example, an emulsifier contains about 100 grams of water, about 1 gram of yellow NATURA™ toner, about 0.4 grams of blue NATURA™ toner, about 0.8 grams of magenta NATURA™ toner, about 2.2 grams of clear NATURA™ toner, and about 0.33 grams of Lyoprint™ PTU-US. An emulsion of the present disclosure may be made by mixing the various components of the emulsion for a period of time until the particles of the emulsion are coated with the emulsifying agent or agents. The coating of the particles may enhance the stability of the formulation. The mixing time depends on the particular components utilized in a formulation and can range from, for example, from about 1 minute or less to about 48 hours, or longer.
In another embodiment, the décor product may be formulated as a stain-removing and masking agent containing a base color such as a white and/or neutral color and/or other color onto which additional desired colors may be overlain. Illustratively, the décor product may contain a pH neutralizing and/or adjusting pretreatment compound such as, for example, a peroxide and/or a bleach, and/or a titanium dioxide-type neutral color application. The décor product may further include a stain-masking agent and/or coloring agent as disclosed herein. Another embodiment contemplates the application of a highly pigmented coating that has a white and/or neutral color that provides a mask and/or hides a color difference (for example, a stain) on a surface. Further, another material with a color matching the bulk fiber of the surface (for example, a carpet or textile) may be applied subsequent to the masking of the stain.
In yet another embodiment, a décor product composition may have a glass transition temperature (Tg) from below about 25° C. up to the melting temperature (Tm) of the surface substrate to which it is to be applied. In a further embodiment, the Tg ranges from about 45° C. to about 75° C., or from about 45° C. to about 60° C., or from about 45° C. to about 70° C., or about 55° C. The Tg and Tm of a composition or a surface substrate may be measured by methods known to those skilled in the art including, for example, dynamic mechanical analysis, thermomechanical analysis, and differential scanning calorimetry. Illustratively, Tg and Tm values of décor products and surface substrates may be determined using a Model Q100 Differential Scanning Calorimeter (TA Instruments, Inc.) at a heating rate of 20° C./min.
In still another embodiment, the décor product composition has an Imperial Chemical Industries (ICI) cone and plate viscosity of equal to or less than about 2,000 centipoises, or about 5 centipoises to about 100 centipoises, or about 15 centipoises to about 50 centipoises, or about 25 centipoises, or about 35 centipoises at about 150° C. to about 200° C. The viscosity of a composition may by measured by methods known to those skilled in the art, including for example, using a Wells-Brookfield Cone/Plate viscometer distributed by Can-Am Instruments LTD and following methods as set forth in D4287-00(2005) “Standard Test Method for High-Shear Viscosity Using a Cone/Plate Viscometer,” ASTM International. Further, a Brookfield CAP 2000H Cone and Plate Viscometer (available from Brookfield Engineering Laboratories, Inc.) set at 750 rpm for 25 seconds using a size six spindle may be used to measure the ICI Cone and Plate viscosity of the décor product composition.
In yet a further embodiment, décor product compositions may have viscosity ranges as measured on a Brookfield LV Viscometer at spindle rotational speeds of 0.3, 0.6, and 60 rpm of about 100 to about 17000, about 100 to about 13000, and about 50 to about 700 centipoises, respectively. For example, a representative décor product formulation may have a viscosity of about 8100 centipoises at 0.3 rpm, of about 5500 centipoises at 0.6 rpm, and about 250 centipoises at 60 rpm.
Application of the décor product contemplated in the present disclosure may occur by any appropriate way that is compatible with the décor product formulation utilized. Illustrative ways to apply the décor product to a surface include the use of an ink jet printer, a jet dye process, silk screening, and/or rotary printing. Further, the décor product may be applied and/or dispensed with and/or by a spray gun, a sheet, a film, a matrix, a roller, a brush, a marker, a pen, a stamp such as a self-inking stamp, a pump sprayer, a trigger sprayer, a pressurized spraying device, a sponge, a squeegee, an airbrush, a fiber separator, a dye applicator, a roller, piezoelectric or heat driven delivery, a manual or electronic sifter, a powder “puff”, a felted/flocked brush, a magnet, and/or a powder paint dispenser. The décor product may be applied in a wet form, such as, for example, as a suspension or emulsion including, for example, a liquid-based solvent, a foam, a spray, a stream, a wet aerosol, or in a dry form, such as, for example, as a powder, a dry aerosol, and/or a powder with a gentle mist.
By way of example, one possible method of applying a décor product to a selected surface is generally depicted in
In another example, a décor product may be applied to a selected surface as generally depicted in
Additional examples of applicators and/or dispensers of the décor product of the present disclosure include, for example, an intermittent pressurized sprayer (such as PULL 'N SPRAY® liquid applicator marketed by The Scotts and Miracle-Gro Company), an actuator spray bottle, a trigger sprayer, a mechanical spray bottle, a squirt bottle for thin liquid stream, a pump and/or pump system, a liquid refill containing the décor product for a pressurized air chamber, an aerosol barrier pack containing the décor product with a driving chamber (with a propellant, for example, carbon dioxide or a hydrocarbon), and a liquid or gel chamber for containing the décor product where use would allow pressurized spraying with reduced propellant release to the atmosphere or room being decorated by the user. Other useful sprayers include those disclosed in, for example, U.S. Pat. No. 6,872,444.
For example,
The container 3021 may accommodate a décor product 3031 and a propellant 3032, as described herein, for application to a surface. A conically-shaped mesh filter element 3040 may be attached to an inlet end 3041 of the valve body 3026 and includes a plurality of pores or holes shown schematically at 3063. Pore sizes of the filter element 3040 may be at least as large as the average diameter of the substantially homogeneous particles contained within the container 3021, and illustratively may range from about 100 to about 500 microns, or from about 80 to about 500 microns in diameter. The number of pores 3063 in the filter element 3040 may range from about 100 to about 500 per area. The mesh filter element 3040 includes a flange portion 3064 that rests or engages the rim or wall 3065 of the lower valve body 3026 to prevent décor product from bypassing the mesh filter element and potentially clogging the valve stem. Filter geometries other than conical shapes are contemplated that could be attached or otherwise integrally molded into the valve body 3026, such as slotted valves with dummy diptubes for handling during manufacture.
Still further other ways to distribute the décor product include, for example, a décor product impregnated sheet that contains entrapped dry or wet décor product particles that when wetted or otherwise activated, releases the décor product onto the surface. Another example includes a décor product impregnated sheet containing entrapped liquid that releases the décor product onto the surface upon pressure application or controlled puncture. A further example includes a décor product impregnated sheet with liquid rolled or stamped thereon that promotes even distribution of the décor product. Still another example includes an apertured or perforated décor product impregnated film that collects and/or directs a releasing substance that once applied to the film releases the décor product onto a surface. Yet another example includes a décor product impregnated matrix containing therein and/or thereon entrapped décor product formulation that releases the décor product onto a surface upon pressure, vibration, liquid transfer, heat application, and/or chemical means and/or by an electrostatic or magnetic deposition device that meters an amount of décor product to be applied to a surface and precisely lays the décor product on the surface.
Still further ways for application of the décor product include a multiple chamber system that mixes the décor product upon dispensing to give the desired décor product color or other characteristic, such as are exemplified in part by trigger release systems (for example, DLS100, DLS 200, or Versitech systems manufactured by Take 5, Anaheim, Calif. (www.take5net.com)), pump systems (for example, VERSADIAL® manufactured by Versadial, New York, N.Y., a company under the Sea Change Group) (www.versadialworld.com)), or a multichamber mixer/dispenser that is combined with a décor product applicator (for example, a brush, a spray bottle, or other applicator). Further, premixed ready-to-use bottles and/or spray cans may be used to distribute and apply the décor product.
Additional technologies contemplated for application and/or dispersion of the décor product include multifunctional devices, such as, for example, a device that combines packaging, design positioning, décor product application, and/or removal of a design device from a surface. For example, in one embodiment, a design device, for example, a stencil contains the décor product, which can be released onto a surface by applying a releasing agent, such as water, to the stencil. As an example, the use of a dry décor product may be reversibly attached to a stencil by means of a water-soluble adhesive or the décor product may be attached to a sticky side of a water-soluble transparent film. Further technologies contemplated include sprayers that impart charges to colorant droplets and/or stencils (similar to powder painting), sponging, and felt tip pens and liners.
The décor product in one embodiment may be applied using heat transfer technology including, for example, that used by color copying machines such as a Xerox DOCUCOLOR™ 12 printing onto Xerox 3RS811 or another similar transfer paper and/or similar combinations of materials provided by Hewlett Packard, Canon, Geo Knight & Co, Avery Dennison, and 3M.
Differing application factors are contemplated for encapsulated décor product particles including control release, temperature release, concentration release, and any other release mechanism known to those skilled in the art. For example, release of the contents of a microencapsulated décor product particle contents may be triggered by changes in pH, such as by applying a common solvent such as, for example, an ammonia-containing solution. Examples of a temperature release mechanism include exposure of the microencapsulated décor product particles to a temperature above a release threshold, where the release of the microencapsulated décor product particle contents only occurs above the predetermined threshold temperature. A concentration release application may apply a portion of a colorant to the surface over an extended period of time to render a more evenly distributed and/or more thoroughly distributed appearance of the colorant to a surface. Illustratively, a microencapsulated décor product particle with a polymer resin particle shell and containing trapped colorant particles and/or other compounds disclosed herein may be activated by thermal activation and/or specific chemistry-related activation (including, for example pH modulation using, for example, ammonia). As such, the outer polymer shell would melt and/or dissolve, and the colorant particles and/or other microparticle contents may be allowed to flow and thus be applied to the surface. Nonexclusive examples of release mechanisms useful in the present disclosure include those found in U.S. Pat. No. 6,893,662. Additional release mechanisms contemplated for treating of the microencapsulated décor particle result in at least one of breaking, heating, weakening, and/or dissolving one or more shells of a décor particle.
A décor product once applied and/or affixed to the surface may be temporary, permanent, and/or semi-permanent. An example of a semi-permanent décor product includes a décor product with a temporary adhesive that adheres and/or attaches a décor particle to the surface. Such a formulation may provide short term durability, for example, hours to weeks, of the décor product on a surface by substantially adhering and/or attaching the décor product thereon. In one embodiment, short term durability allows the décor product to be applied to a surface for an occasion, special event, and/or holiday without the décor product needing to be affixed to the surface and at the same time being easily removable therefrom. An example of décor product attachment to a surface is seen in
Removal of the décor product from the surface may be either through dry removal methods or wet removal methods such as through using various devices and methods including, for example, a vacuum, a vacuum combined with mechanical action such as agitation, wet extraction, steam cleaning, chemical application (for example, applying an organic or inorganic solvent), using an ultrasound process, using detergents, using dilute ammonia solutions, and/or using an abrasive eraser. Some or all of the aforementioned processes may be employed to remove the décor product prior to and/or after setting, affixing, and/or curing of the décor product on or to the surface.
By way of example, reversibility (removability) of a décor product applied to a surface may be determined in the following manner. Initially, a test surface, such as, for example, a two-foot by two-foot square piece of nylon and/or polyester carpet is thoroughly cleaned using an upright vacuum cleaner (for example, a Bissell CLEANVIEW® II vacuum cleaner, manufactured by Bissell Homecare, Inc.) to remove loose fibers and/or dirt. The baseline color of each of three spots over which the décor product is applied is determined using a colorimeter such as a Minolta data processor model DP-301 combined with a Minolta model CR-310 chroma meter (both manufactured by Konica Minolta Sensing Americas, Inc.) set to the “L-a-b” setting to allow determination of ΔE (color change) and calibrated according to the manufacturer's instructions.
The décor product is applied using, for example, a finger pump (output 60 micron particle size) onto the surface of the three spots until the test area is completely saturated. The décor product is allowed to substantially dry to the touch, which is typically overnight to assure complete drying, though shorter or longer periods may be used depending on, for example, the relative humidity and/or temperature of the ambient environment. After the décor product is dry, the color of each of the three spots is determined using the colorimeter as mentioned above. Subsequently, the three spots are vacuumed using a wet/dry vacuum with a hose attachment and brushless triangular tool, such as, for example, a Shop-Vac® 1x1 portable wet/dry vacuum 12 V 60 Hz, 5.5 A, model 2101A (manufactured by Shop-Vac, Inc.). The three spots are vacuumed in one direction several times and repeated in the other direction for a period of to ensure adequate removal. After vacuuming, a colorimeter measurement is taken to determine the change in color. Change in color (ΔE) was determined using the following formula:
ΔE=√(L1−L2)2+(a1−a2)2+(b1−b2)2)
where “L” refers to “lightness” with values of 0=black to 100=white; increasing “a” values indicate more red color and decreasing “a” values indicate more green color; and increasing “b” values indicate more yellow color and decreasing “b” values indicate more blue color. As an alternative, a CIElab coordinate system may be used (Hunter Associates Laboratory, Inc.).
Illustratively, a substantially removable décor product has a ΔE value as compared to the initial reading of an untreated carpet of less than about 20, or less than about 10, or less than about 7.5, or in the range of about 0 to about 15.
Factors that may affect reversibility of the décor product from a surface may include, for example, décor product specific factors, application specific factors, and/or surface specific factors. Examples of décor product specific factors may include the type and/or concentration of emulsifier included in the décor product formulation, which may affect adherent interactions between the décor product and the surface to which the décor product is applied thereto. Further, when the décor product composition includes a particulate component, for example, a décor particle, the reversibility of the décor product may be affected by the size of the particle. Although not wishing to be bound by theory, it is believed that smaller particle size may affect reversibility due to possible greater penetration of the particles into recesses and interstices of a non-smooth surface such as carpet, thus reducing access to the smaller particles for the subsequent removal process.
Application specific factors that may affect reversibility include the extent of surface saturation when applying the décor product to the surface and the method and/or device used to apply the décor product to the surface. Surface saturation includes, for example, the density of applied décor product on the surface. Greater surface saturation may lead to an increased likelihood of residual décor product remaining after removing the major portion of décor product applied to the surface, and/or greater penetration of the décor product into the recesses and interstices of the surface thereby reducing accessibility of the removal process to the décor products. Further, the method and/or application device used to apply the décor product may affect reversibility. Illustratively, the décor product may be applied to a surface in a fashion to coat the surface with little to no surface penetration. For example, an applicator that applies the décor product in a mist, such as by a finger pump with a 60 micron or less spray nozzle, may be used to coat the surface with little or no penetration of the interstices of the surface. In this example, décor product reversibility may be improved owing to the minimal surface penetration of the décor product. However, if it is desired to apply the décor product with an aerosol and/or non-aerosol spray container, or other such applicator that expels the décor product from the container with a greater velocity than, for example, a hand pump, deeper penetration of the surface may result, which may affect removal of the décor product from the surface by, for example, limiting or inhibiting access of the removal process to the décor product.
Surface specific factors that may influence décor product reversibility include, for example, surface structure and/or texture, the electrostatic charge held by the surface, surface contaminants including for example glue, wax, sugars, oils, urine, and/or surface pretreatments affecting, for example, surface tension. Surface structure factors such as fiber density, in the case of carpets and the like, may influence décor product reversibility. For example, dense carpet structures may be more likely to minimize particle penetration as opposed to open structures such as, for example, nylon shag carpets and older carpets with damaged braids. Thus, less dense surfaces may influence décor product reversibility by, for example, reducing the access of the décor product to the removal process as compared to more dense surfaces.
Further, surface electrostatic charge and/or surface tension may influence reversibility. Illustratively, a surface treatment may be used to lower the electrostatic charge and/or surface tension to improve the reversibility characteristics of the décor products. Examples of surface treatments that may be used include 3M SCOTCHGUARD™ Carpet and Upholstery Protector (manufactured by 3M) and/or Advanced TEFLON® Carpet protector (manufactured by E. I. du Pont de Nemours and Company). Further, such pretreatments may promote décor product coverage and/or dispersion on the surface with smaller volumes of the décor product thus indirectly promoting décor product reversibility through minimizing the risk of oversaturation.
In some instances, the décor product may be formulated to have a larger particle size to improve or enhance reversibility by reducing the amount of particles based on size that can penetrate the smaller interstices of the surface. Further, and not wishing to be bound by theory, it is believed that smaller sized particles, for example, particles less than about 5 to about 10 microns in size, may be held relatively more tightly to the surface by an electrostatic charge and/or surface tension as compared to larger particles, for example, particles greater than about 20 microns in size, making the smaller sized particles relatively more difficult to remove from the surface as compared to larger sized particles. Thus, in some embodiments, surface pretreatment, additional effort and/or additional methods may be needed to achieve the same reversibility characteristics for décor products formulated with smaller particles as compared to décor products formulated with larger particles.
Once a décor product of the present disclosure has been applied to a surface and the user has decided to keep the décor product on the surface, the décor product may be cured and/or affixed by chemical curing and/or mechanical bonding to the surface temporarily, permanently, and/or semi-permanently according to the formulation of the décor product. Illustratively, a solubilizing composition or a sealant composition may be applied to the décor product to affect curing and/or bonding to the surface. The sealant may be applied to the décor product at any time including at the same time that the décor product is applied to the surface and/or after the décor product has been applied to the surface. It is also contemplated that the sealant may be applied to the surface prior to the décor product. Depending on the décor product being used, if the décor product was applied in a liquid format or via a liquid carrier, it may be desirable to allow the décor product to dry completely before applying the sealant to the décor product. The décor product may substantially dry, for example, dry to the touch, over a varied amount of time depending on a variety of factors including, but not limited to, the quantity of décor product applied, the application area, the type of surface being used, and other factors related to the exact chemistry and composition of the décor product. Although the exact drying time may vary based on the factors discussed herein, it is contemplated that the décor product may be allowed to dry for more than or equal to about 48 hours, or more than or equal to about 36 hours, or more than or equal to about 24 hours, or more than or equal to about 12 hours, or less than or equal to about 12 hours, or less than or equal to about 16 hours, or between about 12 and about 16 hours, or for at least about 4 hours.
The sealant may also be applied at any other time including while the décor product is still wet or saturated, semi-saturated, or any other physical state. If the décor product is not completely dry when the sealant is applied, the concentration of sealant applied may need to be increased to compensate for dilution.

Non-limiting examples of additional components that may be included in contemplated solvent systems include polar and/or nonpolar solvents, water, wax, hydrocarbons, ethanol, phosphorous esters. benzyl alcohol, isopropyl alcohol, diacetone alcohol, ethyl lactate, a nitrated solvent, a chlorinated solvent, a chlorinated hydrocarbon, a ketone, an ester, acetone, an amine, benzyl acetate, a phenol, an organic sulfone, and dimethyl sulfoxide.
Solvent systems may contain a total glycol solvent content of from about 15% to about 90%, or from about 20% to about 80%, or from about 25% to about 75%, or from about 35% to about 50%, or greater than about 15%, or greater than about 25%, or greater than about 50%, or greater than about 75%, or greater than about 90%, or about 15%, or about 17%, or about 20%, or about 25%, or about 50%, or about 75%, or about 90%, or about 100% by weight or volume of the solvent system
In one embodiment, two or more solvents may be used to counter adverse effects of solvents having differing evaporation rates in the solvent system, for example, to maintain a constant level of solubilizing effect over time as the solvent system evaporates. In the case of mixed solvents, it is helpful to balance the evaporation rates of the individual components so that dissolved components stay in solution until the solvents are nearly completely evaporated (see, for example, J. Bentley and G. P. A. Turner “Introduction to Paint Chemistry and principles of paint technology” 4th edition, pages 132-134, Chapman and Hall, New York, 1998). For example, if a mixed solvent system were to evaporate such that one component preferentially evaporated and caused precipitation of the dissolved solids, the resulting film would be milky or low in gloss due to the formation of particulate precipitates in the bulk of the liquid instead of a thin film on the surface the coating is intended for. On the other hand, preferential evaporation of one solvent may further compromise the sealant capacity of a sealant composition over time.
It is further contemplated that two or more solvents may be employed in a solvent system, where one of the solvents may aid the solubility of the other in an aqueous or non-aqueous solution. Alternatively or in addition, an emulsifier may be used to alter the solubility of one or more solvents in a solvent system. Further, combinations of solvents are contemplated to regulate evaporation rates of each other as well as additional sealant composition constituents.
In another embodiment, reducing amounts of pH buffers may also improve solubility of certain solvents, such as EPH.
Solubilizing agents or sealants contemplated may contain on a weight % basis, at least one of: 1) a foaming agent in an amount of from about 0.01% to about 3%, or from about 0.05% to about 2.0%, or from about 0.1% to about 1.75%, or from about 0.5% to about 1.5%; or about 0.75%, or about 1%, or about 1.25%, or about 1.5%; 2) a solvent system in an amount of from about 2% to about 90%, or from about 3% to about 60%, or from about 3% to about 50%, or from about 4% to about 45%, or from about 4% to about 35%, or from about 5% to about 25%, or from about 6% to about 15%, or about 7% to about 12%, or from about 7.5% to about 10%, or about 6%, or about 7%, or about 7.5%, or about 10%, or about 15%, or about 20%, or about 25%, or about 35%; 3) a propellant in an amount of about 4 to about 10%, or less than about 10%, or in an amount less than 8%, or about 4%, or about 6%, or about 8%, or about 10%; 4) an anticorrosive agent or pH buffer in an amount of from about 0.01% to about 5%, or from about 0.05% to about 4%, or from about 0.15% to about 3.5%, from about 0.07% to about 1.5%, or from about 0.1% to about 0.75%; or about 5%, or about 4%, or about 3%, or about 1.5%, or about 1%, or about 0.5%, or about 0.3%, or about 0.15%, or about 0.1%; 5) optionally an antimicrobial; 6) optionally a solvent solubility agent, such as an emulsifier; and 7) the balance water.
It is further contemplated that a sealant and/or setting solution mixture contemplated herein may include one or more plasticizers that soften carpet fibers (for example, a nylon and/or polyester carpet) and/or make a polyhydroxyl ester material more pliable. Some examples of plasticizers for nylon, polyester, and hydroxyl polyester include alkyl phosphates (for example, Tri-butoxyethyl phosphate (TBEP), isopropylented triaryl phosphates, alkyl diphenyl phosphates, and t-butyl triaryl phosphates available from Akzo Nobel Chemicals Inc.), numerous adipate diesters (for example, dioctyl adipate) available from Arizona Chemical, numerous sebacate diesters (for example, dioctyl sebacate, dibutyl sebacate, among others) available from Arizona Chemical, numerous phthalates (for example, dioctyl terephthalate) available from Arizona Chemical, aliphatic glycols, aromatic sulfonamides (for example, N-(n-butyl)benzene sulfonamide (BBSA), N-(ethyl) o/p toluene sulfonamide (NEO PTSA), p-toluene sulfonamide (PTS), benzene sulfonamide, and the like) available from Advance Coating Co., fatty acid esters of pentaerythytol available from Sunivo Supply Chain Management Co., Ltd.
While not to be bound by theory, it is thought that coincident softening of the carpet fiber and the applied colorant polymer promotes adhesion between the two polymers by creating a soft interface that allows interpenetration of the polymer networks. Furthermore, the high boiling nature of the plasticizer allows it to stay dissolved in the polymer over long periods of time. This is particularly desirable for situations where the presence of the plasticizer softens and toughens the colorant polymer film, allowing it to be more flexible and resilient to crush type forces as imparted by foot traffic and the like, thereby promoting durability.
Plasticizers contemplated in the sealant formulations may be included in an amount of from about 2% to about 90%, or from about 3% to about 60%, or from about 3% to about 50%, or from about 4% to about 45%, or from about 4% to about 35%, or from about 5% to about 25%, or from about 6% to about 15%, or about 7% to about 12%, or from about 7.5% to about 10%, or about 6%, or about 7%, or about 7.5%, or about 10%, or about 15%, or about 20%, or about 25%, or about 35%. In one embodiment, a range such as about 0.1 to about 5%, or about 1% or more may be added to an otherwise completed sealant formulation as disclosed herein.
Additional examples of plasticizers contemplated for use herein include those available from Advance Coatings Co., Akzo Nobel Chemicals Inc., Arizona Chemical, Arkema Inc., BASF Corp. Chemicals, Eastman Chemical Co, Exxonmobil Chemical Co. Polymers Group, Stepan Co. Plastic & Fiber Additives, and Sunoco Chemicals, among others.
In a further embodiment, drying compositions may aid in the affixation of colorant particles affixed via a sealant composition. In this regard, metal complexes of organics, such as those, for example, that may be water or oil soluble. One non-limiting example contemplated herein is zinc ammonium carbonate. Other suitable drying agents are equally contemplated herein.
In a further embodiment, a sealant and/or setting solution mixture contemplated in the present disclosure may have a pH that ranges from about 6 to about 9, or from about 6.5 to about 8.5, or about 7 to about 8, or that is about 6, or about 7, or about 7.1, or about 7.4, or about 8, or about 8.5. An example of a sealant and/or setting solution mixture contemplated in the present disclosure is shown in Table if below.
Examples of setting solution compositions are shown in Tables 1g-1i below.
It is contemplated herein that one or more of the constituents of the setting solution, sealant, or solubilizing composition may serve more than a single purpose. For example, a particular component may serve to improve as a surfactant and may further serve as a foaming agent. Additional components including solvents and propellants, as well as other agents known in the art, such as, for example, expandable liquids, acid-base systems, gas producing systems, and others, may be useful as foaming agents in the present disclosure.
The solvent mixture may be concentrated or it may be diluted with water or other compatible diluents. Water and each mixture component may be present in any amount from about 0% to about 100%. Illustratively, the solvent mixture may contain between about 0% to about 90% of each mixture component, or between about 10% to about 50%, or between about 0.1% to about 35%, or between about 10% to about 35%, or between about 1% to about 10%. The solvent mixture may be, for example, purchased pre-mixed from a supplier and/or may be mixed at some other point. While mixing the solvent mixture together, the components can be added in any order. The solvent mixture may be provided in a single phase, a multi-phase, or may transition over time into either a single phase or multiphase mixture. It may be desirable to make a solvent mixture having only one phase so as to assist in the ease of application to the décor product. In multiple phase form, the solvent mixture may require agitation by the user during the application process.
The sealant composition may be selected to correspond to the specific chemistry and composition of the décor product of the present disclosure. For example, the décor product may include a composition having a liquid carrier, an emulsifier, and substantially homogenous particles as discussed in the disclosure herein. The substantially homogenous particle may comprise a colorant, a catalyst, and a resin, and the resin may be an acrylic, an acrylic latex, a polyester, a urethane, or an epoxy. An amount of composition may be applied to a surface and particulates of the substantially homogenous particles may be formed and attach to the surface.
Factors that may impact solvent selection may include the solvent's ability to bind colorant particles to a surface, the solvent's effect on foaming, the solvent's ability to completely evaporate, the solvent's ability to minimize resoiling, the solvent's toxicity, environmental fate, and environmental impact, the solvents stability, reactivity, and odor, the solvent's ability to dissolve the substantially homogenous particles and the substantially homogenous colorant particles, the solvent's solubility in water, the solvent's evaporation rate, and/or other manufacturing and business considerations, such as cost and availability of the solvent.
The amount of sealant composition that may be applied to the décor product should be an amount enough to effectuate affixation to a surface or an amount enough to achieve a desired effect. The amount may be sufficient to dissolve the substantially homogenous particles and the substantially homogenous colorant particles when they are contacted by the sealant and to allow the dissolved substantially homogenous particles and the substantially homogenous colorant particles to flow onto the surface. The amount may also be sufficient to bond a majority portion of the particulates to the surface. For example, the particulates may be bonded to the surface when less than or equal to about 25% of the particulate bonds to the surface, or between about 25% and about 50%, or between about 50% and about 75%, or between about 75% and about 100%, or about 85%. Several factors may be taken into account in determining the amount of sealant utilized including, for example, the chemical makeup of the décor product, the type of surface the décor product is being affixed to, the area of the décor pattern applied to the surface, the quantity of décor product that was applied to the surface, environmental factors, and/or any other internal or external condition related to the sealant, surface and/or décor product. In some embodiments, the sealant composition may be applied over the entire surface area of the décor product. However, it is also contemplated that the sealant could be applied over a limited portion of the décor product to affix only a limited section of the décor product. Applying the sealant to a limited section of the décor product may result in only the contacted section of the décor product being affixed to the surface. The sealant may be dispensed at any distance that distributes the sealant over the décor product area that is to be affixed. The distance selected may be based upon a number of factors, including, for example, the type of sealant dispenser, the type of spray pattern the dispenser utilizes, the surface area of the décor product to be affixed, and the other components being dispensed with the sealant. For example, the sealant may be dispensed from a distance of less than about 12 inches, or a distance of between about 8 inches and about 12 inches away from the décor product, or a distance greater than about 12 inches. Furthermore, the foaming action of the sealant may provide a visual indicator of amount applied (for example, based on foam thickness), therefore providing realtime guidance of how much sealant has been applied and suggesting how much more may be needed for proper sealing.
In one embodiment, when the sealant composition contacts the décor product, the solvent dissolves the colorant particles and/or thermoplastic resin contained within the décor product. The dissolved colorant then flows onto or into the surface. If the surface is a soft surface, for example a carpet or a fabric, the particles of the colorant may flow into the recesses or crevasses of the surface and penetrate the fibers and form a thin, even coating on individual fibers. The colorant particles mechanically and/or chemically bond to the surface. Depending on the exact composition of both the décor product and the solvent or solvent mixture, other chemical reactions may take place during or after the solvent is applied to the décor product.
After the sealant composition contacts the décor product and the particulates that are attached to the surface, the décor product may be allowed to dry to allow the décor product to affix to the surface. The drying time may be dependent upon a number of factors including the composition of the décor product, the amount of the décor product that was applied to the surface, the type of surface that the décor product is being affixed to, the solvent or solvent mixture that was applied to the décor product and many other variables related to the surface, compositions of the décor product and the solvent, and/or the ambient environment. The drying time may be whatever time is sufficient to substantially affix the décor product to the surface. For example, a majority portion of the sealant composition may be allowed to evaporate from the particulates to affix the colorant to the surface. A majority portion of the sealant allowed to evaporate may be between about 1% to about 50%, or between about 50% and about 75%, or between about 75% and 100%, or about 90% based upon weight of the total sealant applied to the surface. The sealant composition may also be allowed to evaporate from the particulates to affix the portion of the dissolved substantially homogenous colorant particles to the surface. Illustratively, the drying time generally may be at least about 1 hour, about 2 hours, about 4 hours, about 6 hours, about 8 hours, about 12 hours, or between about 16 hours and about 24 hours, or greater than about 24 hours. In some cases, if the décor product/solvent mixture does not have a sufficient time to dry, there may be smearing of the décor product or poor durability.
Many tools and devices may be used to dispense the solvent or solvent mixture. For example, any of the devices or tools referenced herein that are used to dispense the décor product may also be used to dispense the solvent or solvent mixture alone or in combination with each other. The décor product and solvent or solvent mixture may be dispensed from the same dispensing device or from more than one dispensing device. In other embodiments, two distinct dispensing devices are utilized so as to not mix the décor product with the solvent prior to application. Aerosol dispensers, hand pump sprayers, and/or other pressurized systems such as high volume low pressure (HVLP) sprayers or high pressure low volume (HPLV) sprayers may also be used to dispense the solvent or solvent mixture. Any other dispensing device may be used so long as it is capable of dispensing the solvent or solvent mixture. Illustratively, useful dispensing devices for the décor product and/or the sealant composition include, for example, dispensing devices disclosed in for example, U.S. patent application Ser. No. 12/152,311, filed May 14, 2008.
Other components may also be mixed with the sealant composition before and/or after the sealant composition is formulated. The additional components include preservatives, pH buffers, anti-corrosive additives such as, for example, potassium hydrogen phosphate and/or potassium dihydrogen phosphate, surfactants, such as STEPANOL® WA-Extra PCK, available from the Stepan Company, propellants, wetting agents other than traditional surfactants, foaming agents, thickeners, catalysts and/or cross-linkers to react with the colorant, or additional resin to retard evaporation of the solvent. It is also contemplated that any other component referenced herein that could be added into the décor product composition could also be added to the sealant composition and/or could be added to sealant composition in lieu of adding the additive to the décor product composition.
Additional components may also be included with the sealant composition after the sealant composition is formulated. These components may be placed into the dispensing device and may help facilitate the use of the dispensing device and/or may be included with the sealant composition. For example, a surfactant such as sodium lauryl sulfate or a propellant such as nitrogen may be included in an aerosol-type dispensing device. Other surfactants or components that improve the wetting properties of the décor product on the surface may also be included. Other propellants including hydrocarbons may also be used either alone or in a mixture. In one embodiment, hydrocarbons that promote foaming may be used. A pressurized gas such as carbon dioxide may also be included to facilitate the dispensing process. Additional components that are well known to those having ordinary skill in the art may be included in the dispensing device to provide additional benefits.
Once a décor product of the present disclosure has been applied to a surface and the user has decided to keep the décor product on the surface, the décor product may be cured and/or affixed by chemical curing and/or mechanical bonding to the surface temporarily, permanently, and/or semi-permanently according to the formulation of the décor product. Any curing or affixing technique compatible with the décor product and the surface is contemplated in the methods disclosed herein including, for example, the application of energy and/or a chemical to the décor product. Examples of curing or affixing techniques include, for example, heat curing, steam curing, pressure curing, exposure to an electromagnetic field, including for example, ultraviolet radiation, radio frequency curing, a magnetic field, and the like, ultrasound curing, induction heat curing, solar heat curing, exothermic reaction heat curing, convective heat curing, and/or radiant heat curing. Further, curing or affixation of the décor product may be accomplished by exposure of the décor product to the ambient environment.
The décor product in one embodiment may be affixed to a surface using heat in a range from about −7° C. to about 650° C., or about 4° C. to about 400° C., or at a temperature less than about 260° C., or about 20° C. to about 180° C., or about 65° C. to about 120° C., or higher and lower temperatures depending on the surface in which the décor product is applied. Further, the duration of the curing or affixing step is generally décor product- and/or surface-specific, and illustratively, ranges from less than 1 second to about 15 minutes, or from about 15 minutes to about 1 hour, or from about 1 hour to about 4 hours, or from about 5 hours to about 8 hours, or from about 8 to about 12 hours, or longer for curing of the décor product.
Tools that may be used to cure and/or affix the décor product to a surface include, for example, a hot iron, an enclosure or frame containing a CALROD™ heating element suspended over the surface being heated, an enclosure or frame with one or more incandescent light bulbs, a heat gun, an enclosure or frame with a heater and a blower to infuse hot air onto the substrate, an enclosure or frame with an infrared heating element, an enclosure or frame with an ultraviolet light source, a steam-making device, a heated tool (for example, a household iron, an electric griddle, or a hair dryer or objects similar in function but specifically designed for the application), or a microwave emitting device or a radio frequency emitting device. The devices contemplated herein to be used for décor product affixation may incorporate heat sensors and timers to facilitate the affixation process and further protect the surface to which the décor product is being applied from damage from overheating.
Additional ways to affix the décor product to a surface include inductive heating of a décor product containing metal nano- or microparticles, moisture curing systems, adding magnetic enhancements to a deposited décor product, and treatment of additives within the décor product to induce affixation. Further ways to affix the décor product to a surface include those disclosed in the U.S. patents provided in Table No. 1 above.
An illustration of affixation is shown in
An additional illustration of affixation is shown in
Further, solubilizing composition applicators, including aerosol containers and others may incorporate additional features and/or devices that assist in the formation of foam upon application of the solubilizing composition. In one embodiment, such a foaming device may codispense a foaming agent or a foam along with the solubilizing agent and/or composition such that the distribution of the foam is indicative of the coverage of solubilizing composition applied to the décor product and/or surface to which the décor product was applied. In the alternative or in addition to, the foaming device may serve to cause the solubilizing composition to foam, for example by mechanical shear, upon dispensing from the applicator to affect the same result as application of a separate foaming agent. Mechanical shear may be provided, for example, by passing the solubilizing composition through a fine mesh screen at high velocity. In this way, a user may more efficiently affix an applied décor product to a surface by being able to visualize the distribution and amount of the solubilizing composition and thereby facilitating appropriate coverage over the décor product. In addition, it is contemplated that the addition of a foam during the affixation of the décor product by means of a solubilizing composition may add benefit to the affixation process by reducing evaporation of volatile solvents present in the solubilizing composition.
When a composition of the present disclosure is employed in the form of foam, it may, for example, be packaged under pressure in a dispensing device such as an aerosol container in the presence of a propellant and a foaming agent. The foaming agents may be, for example, anionic, cationic, nonionic or amphoteric foaming polymers and/or surface-active agents. Other illustrative foaming agents useful in a foamable delivery system include one or more surfactants, liquid propellants, compressed gasses, or foamable solvents. Illustrative foamable solvents include water, a volatile propellant, a C1 to C6 fluid alkyl or straight or branched alkyl alcohol such as isobutane, an aromatic alcohol, an ether of a sorbitol derivative, propylene carbonate, xylene, methylene chloride, ethylhexanediol, polysiloxanes, dimethyl ether, and mixtures and/or aqueous dispersions thereof. An illustrative surfactant suitable as a foaming agent includes a betaine (for example, a cocamidopropyl betaine), a polyoxyethylene fatty ether, a polyoxyethylene fatty ester, a fatty acid, a sulfated fatty acid surfactant, a phosphated fatty acid surfactant, a sulfosuccinate surfactant, an amphoteric surfactant, a non-ionic poloxamer surfactant, a non-ionic meroxapol surfactant, a petroleum derivative surfactant, an aliphatic amine surfactant, a polysiloxane derivative, a sorbitan fatty acid ester, sodium lauryl sulfate, and mixtures and/or aqueous dispersions thereof available from Stepan Company.
Foams are thermodynamically unstable systems. Since the total surface area in a foam is large, there is a considerable amount of surface energy present. Accordingly, a surfactant may be used to achieve stability so the foam can last for a desired amount of time, such as, for example, less than about 1 hour, less than about 30 minutes, less than about 20 minutes, less than about 10 minutes, less than about 5 minutes, or less than about 1 minute. Therefore, by adjusting the amount and type of surfactant present in a foaming solution, the foam may be dissipated at different times as desired.
As a general proposition, good emulsifying agents, including surfactants are, in general, also good foaming agents, since the factors influencing emulsion stability against droplet coalescence and foam stability against bubble collapse are similar. The stability of a foam depends upon three principal factors: (1) the tendency for liquid films to drain and become thinner; (2) the tendency of foam bubbles to rupture as a result of random disturbances; and (3) change in bubble size. Other factors which may significantly influence foam stability include evaporation and gas diffusion through the liquid films.
Initially, foam drainage takes place mainly by gravitational flow, allowing the spheres of gas in the foam to become closer together. Foaming agents play an important role at this stage in restricting gravitational flow to a level where local disturbances and consequent film rupture is minimized. When the films between the gas spheres have attained a thickness on the order of micrometers, gravitational flow becomes extremely slow. When the bubble wall becomes sufficiently thin to be permeable, the gas in the smaller bubbles diffuses into adjacent bubbles to equalize the pressure and produce larger bubbles. This spontaneous process increases the average bubble size without film rupture. The predominant drainage mechanism then involves liquid being discharged locally via capillary action at positions of interfilm contact known as Plateau borders, where the liquid capacity is relatively high, existing throughout the foam. The final, stable equilibrium product is a fragile, honeycomb structure, in which the separating films have plane surfaces.
Foam drainage causes the liquid films separating the gas bubbles to become thinner. This usually leads to film rupture.
In addition to film drainage, the stability of a film depends on the ability of the liquid film to resist excessive local thinning and rupture occurring as a result of random disturbances. A number of factors may be involved with varying degrees of importance, depending on the nature of the particular foam in question.
For example, when a film is subjected to local stretching as a result of some external disturbance, the consequent increase in surface area will be accompanied by a decrease in the surface excess concentration of foaming agent and a resulting local increase in surface tension. A certain time is required for surfactant molecules to diffuse to this surface region and restore the original surface tension. This increased surface tension may persist for long enough to cause the disturbed film region to recover its original thickness, stabilizing the foam.
The stress that creates regions of higher surface tension is always present in a foam film. The liquid film is flat at one place and curved convexly at another, where the liquid accumulates in the interstices between the bubbles. The convex curvature creates a capillary force, called the Laplace effect that sucks liquid out of connected foam films so that internal liquid flows constantly from the flatter to the more curved parts of the films. As the liquid flows, the films are stretched, new surfaces of higher tension are created, and a counter-flow across the surfaces is generated to restore the thinned-out parts of the films, a process called the Marangoni effect. In this way, the foam films are in a constant state of flow and counterflow, one effect creating the conditions for its reversal by the other. Rupture of the liquid films separating the bubbles leads to coalescence of the bubbles and complete collapse of the foam structure.
Change in bubble size can lead to thinning of the lamellae and may cause mechanical shocks that result in film rupture. As a foam ages, the small bubbles become smaller and the large bubbles grow larger. This occurs because the pressure in a small bubble is higher than that in large bubbles. The difference in pressure between the two bubbles increases until the smaller bubble disappears completely. The resulting rearrangement of the bubbles in the foam could lead to an increased possibility of mechanical shock followed by film rupture and coalescence.
The mechanical properties of the surface films of a foam have a considerable influence on foam stability. First, high bulk liquid viscosity retards the rate of foam collapse. However, high surface viscosity also produces strong retardation of bulk liquid flow close to the surfaces and, consequently, the drainage of thick films is considerably more rapid than that of thin films, which facilitates the attainment of a uniform film thickness. Second, surface elasticity facilitates the maintenance of a uniform film thickness. However, the existence of rigid, condensed surface films is detrimental to foam stability, owing to the very small changes in area over which such films show elasticity.
In one embodiment, a composition described herein such as a foamable composition is packaged in a container as an aerosol. Selection of a suitable container for the aerosol product may be based, for example, on its compatibility with production methods and formulation components, ability to sustain pressure required to propel the product from the container, design and aesthetic appeal, and cost. Suitable containers may be made of, for example, steel, aluminum, glass, plastic, or mixtures thereof. The containers may further employ one or more protective coatings such as, for example, a PAM coating, sodium nitrate, sodium benzoate, ammonium m-nitrobenzoate, morpholine, 2-methyl butynoyl, Expoxol 9-5, sodium n-lauroylsarcosinate, phenolic, epoxy, or vinyl coatings, to enhance the formulation compatibility and/or safe handling. (See, for example, U.S. Pat. No. 7,186,416). Any other known aerosol container and/or protective coating is further contemplated as useful in this regard.
The container may also include two or more compartments permitting individual compositions to be placed into separate portions that are physically separated until dispensed from the container through the valve assembly.
Methods for filling an aerosol container are well known to those of ordinary skill in the art such as those described in, for example, The Aerosol Handbook (Wayne E. Dorland, Caldwell, N.J.), and the Handbook of Aerosol Technology, (R. E. Krieger, Malabar, Fla.). Such methods include, for example, cold fill, under the cup, and pressure fill (through the valve).
An aerosol valve assembly generally includes one or more of an actuator, a stem, a gasket, a spring, a mounting cup, a housing, and a dip tube. To facilitate foaming, the aerosol valve assembly may also include, or be associated with, a foaming device that creates mechanical shear on a composition that is passed therethrough, The materials used in the manufacture of the valve assembly should be inert towards the formulations that pass therethrough, such as, for example, plastic, rubber, aluminum, stainless steel, and mixtures thereof. Various types of valve assemblies known to those of ordinary skill in the art, including spray valves, sliding gasket valves, deflecting gasket valves, and tilt action valves, are contemplated as being useful herein to deliver product from a container. One such valve useful herein may be employed to allow dispensing of product while the container is upright and/or inverted. Other valve assemblies include a metering valve that is configured to deliver specific quantities of a product each time the valve is actuated. In metered valve systems, an auxiliary valve chamber may be employed to regulate the amount of material discharged based on, for example, the volume or dimension of the chamber. The valve assembly may also include an attachment to facilitate delivery of a composition of the present disclosure.
To deliver a foamable composition from an aerosol container, the container generally contains an expelling force generated by a mechanical means, such as a hand-actuated pump or by squeezing the container, or by pressure applied to a self-pressurized aerosol system through, for example, the use of one or more liquefied or gaseous propellants. Other expelling forces known to those of ordinary skill in the art are further contemplates as within the scope of the present inventive subject matter. Further, additional factors that favor desired delivery are contemplated, including, for example, minimizing the ratio of void volume to composition in, for example, squeeze bottle applicators.
Upon activation of the valve assembly, the pressure exerted by the propellant forces the contents of the package out through the opening of the valve. This expelling force allows the composition to be delivered as a fine mist; a coarse, wet or dry spray; a steady stream; or as a stable or breaking foam. The contemplated foams include those intended for deposition on a surface, such as a hard or soft surface. While not to be bound by theory, it is believed that the foaming of the composition may be more attributable to the use of a liquefied petroleum gas propellant rather than one or more surfactant constituents.
The pressure of an aerosol container generally regulates the performance of the foamable delivery system, and can be influenced by the type, amount, and nature of the propellant and/or the components of the composition held in the container. In general, a foaming aerosol system usually operates between about 10 to about 200 psig at about 70° F. Illustratively, foam aerosols may contain about 1 to about 90% propellant, or from about 2 to about 50% propellant, or between about 2.5 and about 20% propellant.
Patents pertaining to specific foam formulations and foam creating devices contemplated for use herein include, for example, U.S. Pat. Nos. 4,847,068, 5,002,680, 5,167,950, 5,397,564, 5,678,765, 5,679,324, 5,725,155, 6,030,931, 6,060,085, 6,126,920, 6,264,964, 6,557,783, and 7,186,416.
In another embodiment, without wishing to be bound by theory, it is contemplated that a combination of a resin solubilizing treatment and heat treatment may act to improve affixation of décor particles associated with a surface. In specific, it is believed that an initial treatment of a solubilizing composition to applied décor particles may lower the amount of energy required during a subsequent application of energy, such as heat, for the purpose of affixing the décor particles to the surface. Conversely, an initial heat treatment of the applied décor particles and/or product followed by application of a solubilizing composition may likewise promote more efficient and/or effective affixation of the décor particles to the surface. Such a synergistic affixation method may decrease the amount of heat and/or solubilizing/solvating agent necessary for adequate affixation, as well as the duration of affixation of the décor product.
Protective coverings may also be applied to a deposited décor product for the purpose of affixing the décor product and/or to add to the resiliency of the décor product to wear. Useful protective coverings include, for example, nanoparticle coating compositions disclosed in, for example, U.S. Pat. No. 6,872,444. Further, fixatives useful in the present disclosure include those used in artistry to fix and/or seal, for example, pastels, pencil, charcoal, crayon, ink, gouache, or watercolor. Such fixatives include those available under the trade names Blue Label Reworkable FIXATIF® (Martin F. Webber Co.), GOLDEN® Archival Spray Varnish (Golden Artist Colors Inc.), KRYLON® Workable Fixative (Krylon Products Group, The Sherwin-Williams Company), and LASCAUX® Fine Art Fixative (Lascaux Colours & Restauro, Switzerland).
It is further contemplated that the surface to which a décor product is to be applied and/or affixed thereto may be conditioned prior to the application of the décor product. Examples of such conditioning include, but are not limited to cleaning, vacuuming, steam cleaning, bleaching, pH balancing, reducing the pH, increasing the pH, sweeping, painting, scrubbing, wetting, texturing, leveling, tilting, drying, heating, cooling, sanding, buffing, coating, removing coatings therefrom, reducing the electrostatic charge of the surface, and/or applying a surface treatment, such as an upholstery and carpet protector including, for example, 3M SCOTCHGAURD™ Carpet and Upholstery Protector (manufactured by 3M) and/or Advanced TEFLON® Carpet protector (manufactured by E. I. du Pont de Nemours and Company), or such additional conditioning as will enhance binding of colorant particles to a substrate.
Illustratively, the durability of a substantially affixed décor product can be expressed in terms of a ΔE (or ΔE*) value by determining the ratio of the ΔE measured between an untreated surface and a décor product affixed on the surface and the ΔE measured between the untreated surface and the décor product affixed and subsequently vacuumed as described herein and subtracting this ratio from 100. Illustratively, the percentage change in ΔE for a substantially affixed décor product has a range of about 0% to about 20% change in ΔE.
A further embodiment of the present disclosure includes the use of a design device that a user may use to control the application of the décor product to a surface for the purpose of creating, for example, a pattern on the surface to enhance the aesthetic effect of the décor product. Possible décor product patterns on surfaces contemplated in the present disclosure include any and all images, patterns, shapes, and/or designs. Preselected or random patterns may also be imparted to a surface using an inherent dispersal pattern from a décor product applicator with or without movement of the applicator over a selected surface during application of the décor product. For example, by using a spray applicator with a cone-shaped dispersal pattern, a user may choose to apply discrete spots and/or circles having diameters that are varied by varying the distance from which the applicator is held from the surface during application of the décor product. Further, a user may move the applicator during application of the décor product over the surface in a predetermined or random pattern to achieve a predetermined or random pattern on the surface. As such, preselected patterns and/or random patterns may be imparted to a surface with or without a design device.
Design devices contemplated in the present disclosure including, for example, those disclosed in U.S. patent application Ser. Nos. 11/447,694 and 12/152,405, may limit, direct, focus, concentrate, guide, dilute, and/or disperse an amount of décor product applied to certain predetermined areas of a selected surface. The design device may include, for example, a stencil, a template, an array, a guide, a frame, a pattern imparting device, a device imparting graphics in a random manner, a manual device, an automatic device, a computer guided device, a programmed device, and/or any combination thereof. The design device contemplated for use herein including, for example, a stencil, may be constructed totally or in part with a material such as, for example, paper, wood, stone, plastic, cardboard, metal, and/or any combination thereof.
Stencils or other design devices contemplated for use in the present disclosure may be designed, constructed, shaped, and/or reshaped, in a predetermined, ordered, disorganized, and/or random manner by means of laser, knife, die cutting, and/or any other appropriate means as determined by the nature of the stencil material (for example, hardness or softness of the stencil materials) to render a predetermined, ordered, disorganized, and/or random shape that allows a predetermined, ordered, disorganized, and/or random deposition of at least a visual design by introducing a décor product on a surface. The stencils may further be laminated and have additional layers applied thereto post-construction and/or post-designing.
An exemplary stencil 60 useful in the present disclosure is shown in
A cross-sectional view of the stencil 60 is shown in
In another embodiment, the material containment layer and the barrier layer may be made of the same material. For example, a dual purpose material (for example, a paper material) that has densities that differ by layers. In this example, the top layer of the dual purpose material corresponds to the material containment layer and has a density that absorbs liquids and/or entraps dry material and/or solids and the bottom layer corresponds to the barrier layer and has a density that prevents passage of liquids therethrough. Further, varying thicknesses may contribute to the functionality of the dual purpose material previously described in addition to or in lieu of varying material densities. Such a dual purpose material may be advantageous over using multiple materials to create a stencil envisioned in the current disclosure by facilitating manufacture of the stencil.
Another stencil that may be used in the present disclosure may also include a fibrous support layer that has securement and/or attachment properties, such as tulle, scrim, VELCRO®, VERSA HOOK from Avery Dennison, and the like. Illustratively, when the support layer is laid upon a surface, the support layer comes in contact with the surface to which the stencil is to be releasably secured in such a way as to adequately secure the stencil to the surface to allow deposition of the décor product upon the surface and render the intended result. The support layer may also comprise other adherent mechanisms, properties, and/or devices such as, adhesive strips, pressure-sensitive adhesive, and/or any standard bonding mechanism known to those skilled in the art. An additional support layer including, for example, a loose grid, web, or mesh-like material including, for example, thread, is envisioned that may be placed adjacent the barrier layer of the stencil. In this embodiment, the cutout portion may extend through the material containment layer, the barrier layer, and the support layer. An exemplary stencil useful in the present disclosure in which the support layer is a pressure-sensitive adhesive includes that disclosed in, for example, U.S. Pat. No. 6,779,443. The support layer may be of sufficient area to minimize unintended exposure of a surface, as well as function to maintain the structural integrity of the stencil.
Stencils that may be used in this application may be substantially resilient to décor product removing means and/or affixation means. The stencil may be used to protect underlying surfaces from the décor product removing means disclosed herein. Further, stencils contemplated within the context of the present disclosure when disposed upon a surface may protect portions of the selected surface from at least one of application, removal, or affixation of the décor product by means of at least one of the material containment layer or the barrier layer. Further, a design device may protect an area adjacent to the preselected pattern from receipt of the décor product.
Stencils contemplated in the present disclosure may have cutout portions and/or peripheral edges substantially shaped into a desired pattern, shape, and/or design. Illustratively, as seen in
The stencil may also have one or more cut-out portions and/or pre-cut punch-out portions that may be selectively removed by a user. Reverse image stencils contemplated in one embodiment may be used to impart a reverse visual image upon a surface by first being placed upon the surface to which a décor product is intended to be applied. In this embodiment, the peripheral edge of the stencil is cut and/or constructed to impart a pattern, shape, and/or design to a surface when a décor product is applied to the stencil and underlying surface. It is envisioned, that the reverse image stencil may or may not have a cutout portion therethrough. After the placing of the stencil or stencils, the décor product is applied to both the surface and the stencils. The stencil or stencils function to protect the underlying surface in the shape of the desired image resulting in a décor product-free area in the shape of the desired image surrounded by a décor product covered area outlining the desired shape. Further, conventional stencils contemplated in the present disclosure may be used to impart a visual image upon an intended surface by first being placed upon the surface to which a décor product is intended to be applied, after the placing of the stencil or stencils the décor product is applied to both the surface and the stencils, and the stencil or stencils function to protect the surface surrounding the shape of the desired image resulting in a décor product covered area in the shape of the desired image surrounded by a décor product-free area outlining the desired shape.
Another illustrative stencil imparts an image to a surface when used in conjunction with the décor product removal means, such as, for example, a vacuum, after the décor product has been applied to the surface. In this example, the décor product is first applied to the surface and the stencil is placed on the surface where the décor product had been applied. After the stencil has been applied to the treated area, a user may apply a second décor product to the treated area and stencil to impart multiple patterns of different décor products a surface. This process may be repeated until a desired affect is achieved. Alternatively, after applying the stencil to the treated area, the décor product that remains exposed within cutout portions of the stencil and/or in areas surrounding the peripheral edges of the stencil may be removed by décor product removing means disclosed herein. The removal of the décor product results in images similar to those with the reverse image stencils and/or the conventional stencils disclosed above.
One or more stencils may be used simultaneously to apply a visual design to a surface. When desired, one or more stencils may be used in combination with any number of other stencils contemplated in the present disclosure and/or auxiliary devices that aid in design formation and/or stencil communication. A multiplicity of stencils intended to be used together to impart a design or other graphic representation on a selected surface may be coordinated with relation to one another and the room or volume of choice by coordinating, aligning, interfacing, connecting, and/or guiding systems that secure the stencils either together or apart from each other or from predetermined or random positions within a room or other volume either on the surface on which the décor is intended to be applied or any other point in the room or other volume. Examples of coordinating, aligning, interfacing, connecting, and/or guiding means useful herein include reusable or disposable pegs that anchor stencils and/or additional auxiliary devices that aid in design formation and/or stencil communication together via peg securement locations, color strips disposed along a surface of the stencils, letters, symbols, notches, and/or other indicia that guide assembly of the stencil organization. An example of a stencil coordinating mechanism is illustrated in
By using of a plurality of pegs 90 along with the layout tool 102, a user may construct an array 112 of pegs attached to the surface 104 as is seen in
Use of coordinating, interfacing, and/or guiding means may allow the consumer to impart a décor product in predetermined or random patterns, designs, images, lines, geometric shapes, discrete images, and/or repetitive images and the like, in a visually perceived organized manner or a visually perceived disorganized and/or random manner.
Any and all images, patterns, shapes, and/or designs may be imparted on a surface using the design devices of the present disclosure. For example, images, patterns, shapes, and/or designs contemplated in the present disclosure may be regular or non-regular, linear or non-linear, and repeatable or non-repeatable patterns, including, for example, ornamental, tracery, or geometric forms, simplified primitive and symbolic images and patterns, compositional multi-object landscapes, images depicting real or imaginary stories or plots, images with text, art images, standard and/or reproducible images, real or imaginary letters, real or imaginary numbers, cartoons, real or imaginary typographical symbols, illustrations, patterns, designs, indicia, and/or shapes, and combinations thereof.
Further, images, patterns, shapes, and/or designs useful in the present disclosure may be varied by palette, combination of standard or random images, size, positioning on a surface and/or customized by combination of multiple parameters, for example, pictures, patterns, palette, size, positioning, among others. The images, patterns, shapes, and/or designs useful in the present disclosure may also be varied by coloring with reflective and/or refractive elements, optical effects provided by an overcoat, the use of optical properties of static or dynamic flat images, and/or use of tactile properties imparted to a surface by additives and/or by affixation of the décor product.
It is further contemplated that images, patterns, shapes, and/or designs useful in the present disclosure may also be chosen by the consumer based on like or dislike, visual evaluation by comparing an image with a standard set of images, colors, and/or templates. The images, patterns, shapes, and/or designs useful in the present disclosure may also be chosen based on an interactive digital library with changeable parameters for adjustment to specific room or other volume environments, and may also be based on computer modeling for a specific room or other volume.
Further still, the images, patterns, shapes, and/or designs contemplated may be, for example, the result of freestyle design, the creation of single color images using varied forms of stencils, the creation of multiple color images using several stencils, the creation of multiple color images using compound stencils where with a sequential and possibly repeated manner one color is applied to a surface and stencil, then a layer of stencil removed and a protective layer added to protect the first color and/or a second color is immediately applied creating a color mixture on the dual exposed areas and a single color area on the single exposure areas, transfer of prefabricated images from a carrier, and/or sequential image fabrication from standard elements such as lines, dots, and/or pixels.
Additional images, patterns, shapes, and/or designs contemplated may be unique art work, single independent images, one or more systems of connected, potentially interrelated images coordinated with the immediate environment (with a room or objects within or characteristic of a room), and/or a two way coordination of decorative images on one or more surfaces and immediate surroundings. Further, images, patterns, shapes, and/or designs contemplated may serve purposes beyond visual ornamentation, such as teaching, directing, and/or instructing, including prompts, reminders, messages, alphabets, maps, equations, phrases, poems, warnings, language tools, or indexing means (for example, bar codes).
It is also contemplated that combining one or more décor products with at least one stencil allows a user to create images that may be monochromatic with constant or varied intensity and with or without shadow effects. Further, images possible using the present disclosure may also be polychromatic with constant or varied intensity and with or without shadow effects, or may be two or more color contrast images achieved via multiple patches of colors and shapes. Polychromatic images may have mixed or intermediate colors and may or may not provide complete and natural palette. Any number of variations to the appearance of a treated surface may be achieved using the compositions of the décor product envisioned in this disclosure along with or more design devices.
An example of using the décor product with a design device is described hereafter. As seen in
In addition to selecting one or more design devices, a user may select one or more décor products to be incorporated into the design that may differ, for example, by color. One or more consumer aids may be used to assist the user in making these selections. The design mechanisms may include, for example, a user making a simple decorating decision, such as determining an arrangement of design devices and colors to sophisticated computer design aids, such as CD-ROM training programs that teach color application or provide creative suggestions. Additional consumer aid design mechanisms include color analysis, matching, and blending, and may include the use of colorimeters, color scanners, and/or software algorithms. Further examples of consumer aids, are disclosed herein.
Once the user has selected one or more design devices, the user then places the design device adjacent the carpet (step 214). The one or more design devices may be placed in any arrangement on the carpet and may cover a small portion of the surface, such as a center, edge, or corner, or substantially the entire carpet, or any amount therebetween.
After the one or more design devices have been placed in a desired arrangement on the carpet, the user applies a décor product to a cutout portion of the design device at step 216. Alternatively, or in addition to, the décor product may be placed on portions of the design device that directly contact (for example, a non-cutout portion of the design device) the soft surface. Upon contacting the surface, the user may allow the décor product to substantially dry on the surface at step 218. After application of the décor product the design device may be left in place while the décor product dries or may be removed from the surface immediately after application at step 220. If the used decides not to keep the design on the surface, the user may substantially remove the décor product from the surface as described herein at step 222. Otherwise, if the user decides to keep the design, the user may substantially affix the décor product to the surface as described herein at step 224. Further, the design device may be removed from the surface before or after the décor product is removed from or affixed to the surface.

Further, and as shown in
The user may then apply (for example, by spraying) the décor product on the cutout portions of the stencils 270, 280, 1000, 1100. After applying the décor product, the user may remove the stencils to view the design or pattern produced on the carpet by the remaining décor product 1520. A sample pattern created by the remaining décor product 1520 is shown generally at 1500 in
Illustratively, a user may operate a first dispensing device to apply the décor product 1520 to the surface with or without using stencils or other design aids. The user may then operate a second dispensing device containing the sealant composition to apply the sealant composition to the décor product 1520. Before and/or after allowing the décor product to dry, the user may cover the entire section of the décor 1520 product with the sealant composition or may only cover a section of the décor product 1520 with the sealant composition. After the sealant composition dissolves the décor product 1520 composition and after the sealant composition evaporates from the particulates, the décor product 1520 is affixed to the surface.
In yet an alternative embodiment, a room 1600 is shown in
In addition to creating discrete images and the like as disclosed above, the present disclosure may be used as a resource for large area interior design in a commercial and/or non-commercial setting. In this capacity, the present disclosure may be used, for example, to create a border on a surface that would be monochromatic (solid, discrete design, random design) or polychromatic (solid, discrete design, random design) or to create a whole room change such as discrete shapes, images, design, random shapes by applying a monochromatic solid or non-solid or a polychromatic solid or non-solid décor product (full coverage) from wall to wall or that would account for complex room peripheries, such as fireplace stoops, door/entryways, jogs in walls, carpet to non-carpet thresholds, sunken or raised portions in rooms, floor vents, outlets, other built in items disruptive of surfaces in general.
Still further, the present disclosure may be used for creating a discrete image in a selected area of interest as determined by the user such as, for example, a wall, a ceiling, a doorway, an entryway, a walkway, a hallway, a stair, or a flight of stairs, or at the top of a flight of stairs, or in front of or over a hearth or fireplace.
The present disclosure also provides kits that contain one or more components herein described, including, for example, a design device and/or a décor product that may be substantially removed from a surface prior to being affixed thereon. A set of instructions may also be included in the kit instructing the user how to apply the design to a soft surface such as a carpet.
The kit may further include one or more application devices for transferring the décor product to the carpet and/or one or more fixative devices for affixing the décor product to the surface. For example, it is contemplated that the kit may include a first dispensing device containing the décor product and a second dispensing device containing the sealant composition, although the décor product and sealant composition may also be dispensed from a single dispensing device. The dispensing devices may take any form, but may be an aerosol-type can or other hand-held dispensing device such as, a hand-pressurize device or a trigger-actuated device. Any dispensing device referenced herein may be used as well as any possible device that enables a user to apply the décor product and/or sealant composition to the surface. Illustratively, the kit may contain a first dispensing device having a composition, where the composition includes a liquid carrier, an emulsifier, and substantially homogenous colorant particles. The substantially homogenous colorant particles may include a colorant, a catalyst, and a resin, and the resin may include at least one of an acrylic, an acrylic latex, a polyester, a urethane, or an epoxy. The kit may further include a second dispensing device containing a sealant composition and an optional set of instructions to assist a user in applying the composition and/or the sealant composition to a surface.
In addition, the kit may include a protective covering for protecting the décor product after it has been applied to the carpet, especially while it is drying. The kit may further include a screen that is used to provide a user with an indication of what areas of the décor product have already been ironed or affixed.
As an example, the kit may be provided having one or more stencils, for example, five stencils, a décor product, an application device such as an aerosol dispenser, an affixing device such as an aerosol dispenser containing a sealant composition (for example, an organic solvent), and/or a set of instructions. The kit may also include a system to identify, choose, make, modify, and/or prepare the surface on which the décor product is to be applied.
Numerous options for customization of the present disclosure may be utilized with the assistance of one or more consumer aids. Consumer aids contemplated in the present disclosure, which may be provided in a kit, individually and/or in any suitable fashion, include any and all design mechanisms and/or aids and devices that enable the consumer to use the present disclosure including instructions, color predicting aids, design templates showing the look prior to and/or after decorating possibly using a software algorithm to present a retrospective view of a surface treated with the décor product, instructional videos, CD-ROMs, internet web pages to select and predict designs, colors, and overall looks, interactive computers terminals, in store displays, customer service, advertising, training courses, recorded messages, text messages, mailings, books, literature, lectures, training courses, correspondence courses, and any combination thereof, as well as, other communicating means.

Further consumer aids include color templates, for example, sheets of opaque or clear material of different colors with different colors of décor product affixed thereon with instructional ratios of the base colorants used to make each décor product color to allow the user to make each décor product color from the separate base colorants and other additives. One example of a consumer aid contemplated herein is disclosed in U.S. patent application Ser. No. 12,317,633.
Illustratively, in
Additional consumer aids include carpet templates, stencil templates, for example, templates illustrative of different images and image characteristics that are possible or desirable to a user, as well as how different stencils can be used together, positional templates, for example, templates that indicate to a user how a décor product image can be incorporated on a surface in a given space, tester samples (similar to the tester samples supplied by Benjamin Moore & Co.), trial periods, color matching sheets, for example, similar to color matching sheets used in make-up matching to skin tones, used to match colors, or to predict color look and contrast, color blending sheets, for example, similar to color matching sheets that further allow a user to preview combined colors on a surface, color charts, color graphs, color analysis devices, colorimeters, color scanners, software algorithms for color assessment and formulating colors, and other means for determining proportions and types of décor product to be used for a specified or unspecified surface in a room, hallway, house, building, or other area.
In addition, by mixing differently colored décor products, any number of additional colors may be formed. As an example, a user may purchase one or more pre-formulated décor products including colored toners and/or other décor particles or may mix various colored toners to achieve any desired color. Design mechanisms such as color charts, color analysis devices, or other ways for determining the proportion and type of colored toner to achieve a particular color can also be provided to a user. Additionally, a user may directly apply the toners to the surface or the toners may be incorporated into the décor product such as by mixing the toner with water or another solvent, or a predetermined formulation of more than one part to make a liquid suspension or emulsion, for example, and then applied to the surface.
Additional consumer aids include devices to be employed by the user to help the user identify, (for example, tools and/or kits used to identify the type or composition of carpet fibers to help direct the user toward a particular décor product formulation), choose, make, modify (for example, kits or compounds that can be included in kits to alter the physical appearance of a surface, such as an embossing compound), combine, and prepare surfaces on which a décor product may be applied and/or affixed. These consumer aids enable the user to choose the correct décor product formulation for a given surface to have a given intended effect, for example, a textured look on a soft surface or a smooth look on a hard surface, or any combination thereof.
Further, the consumer aids will help users in choosing, making, modifying, combining and/or preparing design devices, such as a stencil, to render images, patterns, shapes, and/or designs to be imparted to the surface when applying the stencil and/or a décor product to the intended surface. Still further, the consumer aids contemplated help or assist the user in choosing, using, making, modifying, and/or preparing décor product formulations that may be ready-to-use or require preparation prior to application to a surface.
In addition to selecting one or more design devices, a user may select one or more colors to incorporate into the design. One or more design mechanisms may be used to assist the user in making these selections. The design mechanisms may include, for example, a user making a simple decorating decision, such as determining an arrangement of design devices and colors to sophisticated computer design aids, such as CD-ROM training programs that teach color application or provide creative suggestions. Additional design mechanisms include color analysis, matching, and blending, and may include the use of colorimeters, color scanners, and/or software algorithms.
Additional consumer aids may take the form of store displays and/or presentations of the disclosure, including, for example, the décor product packaged in liquid form or powder form to be suspended in liquid immediately before use, and/or one or multiple décor product colors and décor product additives to be mixed before use, and/or a kit comprising elements of the present disclosure such as multiple or single colors, one or more designs, instructions, an application device, a fixative device, a protective covering, and/or an iron screen or other indicator, such as, for example, a color changing additive, to differentiate between fixed and unfixed areas of the applied décor product.
Illustrative chemistries useful in a décor product composition includes a low temperature cure epoxy décor particle, a low temperature cure epoxy-polyester hybrid décor particle, and/or a low temperature cure polyester-triglycidyl isocyanurate (TGIC) décor particle. Typical ranges of constituents of the aforementioned décor particles contemplated in the present disclosure include an amount of binder, which includes at least a polymer or resin and one or more curatives, based on weight percentages of about 50% or greater of the total weight of the décor particle. Further, other components of the décor particle, including, for example, additives, fillers, pigments, degassing agents, flow additives, and the like, may be included in amounts ranging from about 50% or less of the total weight of the décor particle. Such ranges may be adjusted to attain the desired characteristics of the décor particle as appropriate as is known to those skilled in the art. Further, to assure full stoichiometry of reactions between polymers and/or resins and curatives, amounts of polymers and/or resins and curatives used may range from about 50% to about 150% based on relative equivalent weights of the compounds and/or as recommended by the manufacturer.
A low temperature cure epoxy décor particle may include a binder system that has an epoxy resin and a curative. An example of an epoxy resin is a bisphenol A resin having the following general chemical structure of Formula I:
wherein n is an integer from 2 to 20.
Bisphenol A epoxy resins useful in a décor particle include those resins having an epoxy equivalent weight of about 650 to about 900, or about 700 to about 750; a Tg of about 45° C. to about 75° C., or about 55° C.; and/or an ICI cone and plate viscosity of about 5 poise to about 100 poise, or about 35 poise at 150° C.
Another example of an epoxy resin useful in a décor product formulation is a novolac epoxy resin. Examples of novolac epoxy resins include the following general chemical structures of Formulas II and III:
wherein n is an integer from 1 to 4.
The glass transition temperatures and viscosities of the novolac epoxy resins are similar to those provided above for the bisphenol A epoxy resins. A curative agent useful in a binder system that has an epoxy resin includes, for example, a phenolic curative. An example of a phenolic curative agent is Huntsman Hardener XB 3086 supplied by Huntsman Advanced Materials (Switzerland) GmbH, which is compatible with bisphenol-A-based epoxy resins and novolac-epoxy-based resins. The Huntsman Hardener XB 3086 contains phenol, 4,4′-(1-methylethylidene)bis-, polymer with 2,2′-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[oxirane] (commonly described as a polymer of epoxy resin and bisphenol A), a Huntsman Advanced Materials confidential accelerator, and Phenol, 4,4′-(1-methylethylidene)bis- (commonly known as Bisphenol A). The Huntsman Hardener XB 3086 has the following properties: amine value of 0.83-0.93 eq/kg, recommended combining weight of about 135, and a softening point of 84° C. to 94° C.
Stoichiometric ratios of the epoxy resin and the curative are calculated based on the combining weights, or equivalent values, of resins and curatives. Values of the combining weights may be determined by chemical structure (for example, average molecular weight divided by the number of reactive groups, amine values, acid or hydroxyl numbers, etc.) or empirically based on laboratory experiments. For example, using a lower molecular type 3 bisphenol A epoxy resin with an epoxy equivalent weight (EEW) of 700 and Huntsman Hardener XB 3086 with a manufacturer recommended equivalent weight of 135, the calculation for a full (100%) stoichiometry is shown below in Table No. 2.
In other embodiments, the epoxy resin and curative agent ratio may range from, for example, about 84% to about 85% epoxy resin to about 16% to about 15% curative agent. To lower the cure temperature of an epoxy décor particle, accelerants and/or catalysts such as, for example, a phenolic curative may be incorporated into the composition. An illustrative phenolic curative has a combining weight of about 100 to about 500. Other accelerants and/or catalysts compatible with epoxy resins known to those skilled in the art may also be used. An illustrative cure condition for an epoxy-polyester hybrid décor particle includes a bake time of about 15 minutes at about 150° C., or less.
The low temperature cure epoxy décor particle composition may include any desired colorant and/or additive. Illustratively, a low temperature cure epoxy décor particle composition may include the following constituents as shown below in Table No. 3.
Another illustrative chemistry useful in a décor product is a low temperature cure epoxy-polyester hybrid décor particle that has a binder system having a low temperature cure epoxy and a polyester resin. Illustrative epoxy resins include the bisphenol A epoxy resins or Novolac epoxy resins described above. An illustrative polyester resin includes an acid terminated saturated polyester resin. The polyester resin may have an acid number of between about 75 and about 85. Example includes acid terminated saturated polyesters used as a co-reactant in epoxy-polyester hybrid coating powder formulations. The polyester may be synthesized from neopentyl glycol, terephthalic acid, trimellitic anhydride, and other types of glycols and dibasic organic acids. The branched polyesters may have resin functionalities of about 2 to about 4, or of about 2.5 to about 3.5 (indicating, that about 2.5 to about 3.5 carboxyl groups per polyester molecule). Resin acid numbers may range from about 35 to about 90 with hydroxyl numbers of about 5 to about 10 (residual hydroxyl). Acid terminated, saturated polyester resins suitable for combination with epoxy resins may have an acid number of about 70 to about 90, or about 80; a calculated combining weight (combining weight equals 56,100/acid number) of about 625 to about 800, or about 700; a glass transition temperature about 45° C. to about 60° C., or about 55° C.; and/or an ICI cone and plate viscosity of about 15 poise to about 50 poise, or about 25 poise, at about 200° C.
To lower the cure temperature of an epoxy-polyester hybrid décor particle, an accelerant and/or catalyst such as, for example, a stannous-organic and/or imidazole-type compound may be incorporated into the composition. Other accelerants and/or catalysts known to those skilled in the art may also be used. An illustrative cure condition for an epoxy-polyester hybrid décor particle includes a bake time of about 15 minutes at about 150° C., or less.
Stoichiometric ratios for an epoxy-polyester hybrid décor particle may be calculated based on the combining weights of resins and curatives. However, as known in the art, molecular structure and chemical functionalities may differ and fluctuate for organic polymer products, making the depiction and calculation of chemical reactions more difficult and ambiguous than for inorganic chemical reactions. Illustratively, stoichiometric ratios may be calculated based on combining weights (also referred to as equivalent values) of epoxy and acid-terminated polyester resins. The values of the combining weights may be determined by chemical structure (for example, average molecular weight divided by the number of reactive groups, amine values, acid numbers, etc.). For example, a lower molecular weight type 3 bisphenol A epoxy resin with an epoxy equivalent weight of 700 and an acid terminated saturated polyester resin with an average number of 80 (combining weight of polyester equals 56,100 divided by 80, which equals approximately 700), provides a full (100%) stoichiometric calculation as shown below in Table No. 4.
The low temperature epoxy-polyester hybrid décor particle composition may include any desired colorant and/or additive. Illustratively, a low temperature cure epoxy-polyester hybrid décor particle composition may include the following constituents as shown below in Table No. 5.
Another illustrative chemistry useful in a décor product is a low temperature cure polyester-triglycidyl isocyanurate (TGIC) décor particle. Illustratively, a polyester includes an acid terminated saturated polyesters synthesized using, for example, a monomer such as trimethylolpropane, terephthalic acid, neopentyl glycol, adipic acid, hexanediol, 1,4-cyclohexyldimethanol, and isophthalic acid, and pentanediol. The polyesters in one embodiment have resin functionalities of about 2.05 to about 2.2 (that is, about 2.05 to about 2.2 carboxyl groups per polyester molecule). The resin acid numbers may range from about 20 to about 60, or range on average from about 28 to about 38. The hydroxyl numbers may range from about 5 to about 10 (residual hydroxyl). TGIC is a trifunctional epoxide resin that is used as a hardener in polyester-based powder formulations. The combining weight of TGIC is 106. Illustratively, an acid terminated, saturated polyester resins suitable for combination with TGIC in a low temperature cure polyester-TGIC décor particle possess, for example, an acid number about 30 to about 40, or about 35; a calculated combining weight (combining weight equals 56,100 divided by acid number) of about 1,400 to about 1,870, or about 1,600; a glass transition temperature about 45° C. to about 70° C., or about 55° C.; and/or an ICI cone and plate viscosity of about 15 poise to about 50 poise, or about 25 poise, at 200° C.
To lower the cure temperature of a polyester-TGIC décor particle, an accelerant and/or catalyst such as, for example, triphenylethyl phosphonium bromide and/or imidazole-type compounds may be incorporated into the composition. Other accelerants and/or catalysts known to those skilled in the art may also be used. For example, glycidyl curative chemistries such as aliphatic, cycloaliphatic, aromatic, and methacrylate-based glycidyl compounds with equivalent weights of about 50 to about 1,000 and melt temperatures below about 125° C. may by utilized in the low temperature cure polyester-TGIC décor particle. An illustrative cure condition for a polyester-TGIC décor particle includes a bake time of about 15 minutes at about 135° C.
As mentioned above, molecular structures and chemical functionalities may differ and fluctuate for organic polymer products. Illustratively, stoichiometric ratios are calculated based on the combining weights of epoxy and acid terminated polyester resins. Values of the combining weights may be determined from the chemical structure of the respective compounds. For example, an acid terminated saturated polyester with an average acid number of 35 (combining weight of polyester equals 56,100 divided by 35, which equals approximately 1,600) combined with TGIC, provides a full (100%) stoichiometric calculation as shown below in Table No. 6.
Due to the large molecular size of the polyester resin and the small molecular size and spherical shape of TGIC, a about 10% to about 15% stoichiometric surplus of TGIC may be utilized to achieve, for example, a polyester resin/TGIC ratio of 93/7.
The low temperature polyester-TGIC décor particle composition may include any desired colorant and/or additive. Illustratively, a low temperature polyester-TGIC décor particle composition may include the following constituents shown below in Table No. 7.
An alternative carboxyl polyester resin curative to TGIC includes, for example, PRIMID® (EMS-PRIMID, a unit of EMS-Chemie AG). PRIMID® is a beta-hydroxyl alkyl amide curative. However, PRIMID® may require longer cure times than a TGIC-based chemistry, as well as a PRIMID® based coating may appear slightly more orange than a TGIC-based coating. Pinholes and blistering may also be an issue with the use of a PRIMID® based décor particle where a coating thickness exceeds 4.0 mils.
For example, a low temperature polyester-PRIMID® décor particle composition may include any desired colorant and/or additive. Illustratively, a low temperature polyester-TGIC décor particle composition may include the following constituents shown below in Table No. 7a.
Polyurethane based décor particles may be arrived at by combining a hydroxyl polyester resin with a triazole blocked polyisocyanate cross-linking agent, and may further include any desired colorant and/or additive. Illustratively, a low temperature polyurethane décor particle composition may include the following constituents shown below in Table No. 7b.
An example of epoxy-functional acrylic copolymer-based décor particles may be arrived at by combining an acrylic epoxy resin with a polyamine cross-linking agent and a carboxylic acid-based crosslinker, and may further include any desired colorant and/or additive. Illustratively, a low temperature acrylic epoxy décor particle composition may include the following constituents shown below in Table No. 7c.
A further example of epoxy-functional acrylic copolymer-based décor particles may be arrived at by combining an acrylic epoxy resin with a modified polyamine cross-linking agent, and may further include any desired colorant and/or additive. Illustratively, a low temperature acrylic epoxy décor particle composition may include the following constituents shown below in Table No. 7d.
As mentioned above, a décor product, which includes a décor particle, may include any desired colorant and/or additive. Illustratively, the décor particle composition may include, for example, a flow additive, a degassing agent, a surfactant or wetting agent, an antioxidant, a heat stabilizer, a ultraviolet light absorber, a wax, a silicone additive, a catalyst, a texturing agent, an electrical charge control agent, an electrical conductivity agent, a processing aid, a filler, and combinations thereof.
Flow additives may be utilized in formulating a décor particle composition to, for example, reduce or prevent cratering of a finished cured product and/or to improve flow and leveling. Illustratively, the flow additives may be low molecular acrylic polymers, either in liquid form (for example, a liquid containing about 100% active substance), or in solid form (for example, a solid with about 65% active substance). Examples of flow additives include Acronal® 4F (about 100% active, BASF), Byk 363 P (about 65% active, BYK-Chemie), RESIFLOW® P-67 (manufactured by Estron Chemical), RESIFLOW® PF-67 (about 65% active, Estron Chemical), MODAFLOW™ 3 (about 65% active, Monsanto), and POWDERMATE™ 486 CFL (about 65% active, Troy Corp.). Illustratively, a flow additive may be added to a décor particle composition in a range of between about 0.3% to about 1% of 100% active flow additive per total formula weight of the décor particle.
A degassing agent may be added to a décor particle composition to, for example, aid in the evaporation of volatile products within the composition during the heating and/or curing cycle to reduce and/or prevent pinholing (volatile bubbles being trapped at the surface boundary between the finish and the air). Some degassing agents, such as Benzoin (Velsicol Chemical Corp.), may solvate the resin/curative mix during the liquid phase of the cure process. Other degassing agents are surfactant-like and other are wax-like and affect the surface tension of the film surface to promote degassing. Illustratively, a décor particle composition may contain from about 0.2% to about 2% of active degassing agent per total formula weight of the décor particle. For example, a décor particle that is curable between about 135° C. and about 149′C (for example a polyester-PRIMID® chemistry), may contain a combination of about 1% to about 1.8% OXYMELT® A-2 or A-4 (Estron Chemical) and about 0.2% Benzoin per total formula weight of the décor particle.
A surfactant or wetting agent that may be used in a décor product or décor particle composition may, for example, promote colorant and/or filler wetting, and/or improve the flow and/or leveling of a finished cured product. In addition, a surfactant or wetting agent may promote substrate wet-out during the cure reaction, which may improve adhesion and/or corrosion resistance. The addition of surfactants may also increase gloss and distinctness of image of the cured film as well. Illustratively, surfactant levels can range from 0.1% to about 0.5% of active substance per total formula weight of the décor particle. Examples of surfactants or wetting agents include cationic, anionic functional organic compounds, silane, and polysiloxane, including, for example, NUOSPERSE™ 657 (manufactured by Elementis Specialties) and SURFYNOL™ 104 S (Air Products and Chemicals, Inc.). Further, surfactants contemplated for use herein may also be used to aid in suspension stabilization. For example, a sodium dioctyl sulfosuccinate sold as AEROSOL® OT-SE available from Cytec Industries, Inc. (West Paterson, N.J.) is contemplated for use herein. Further suitable examples include the Tergitol™ line of products from Dow Chemical, sodium lauryl sulfate, the Pluronic® product line from BASF, and the Tween® and Span® series of surfactants from Croda International.
An antioxidant or heat stabilizer may be used in a décor particle composition to, for example, inhibit or prevent heat induced yellowing during the curing and/or heating cycle. Illustratively, an antioxidant or heat stabilizer may be used in a white or relatively light colored décor particle composition in an amount from about 0.2% to about 0.5% of active substance per total formula weight of the décor particle. More or less antioxidant or heat stabilizer may be used with other colored décor particles. Examples of antioxidants include Irganox® 1076 (Ciba Specialty Chemicals Corp.) and Irganox® B-225 Ciba Specialty Chemicals Corp.). An example of a heat stabilizer is Sandostab® P-EPQ (Clariant).
Anticorrosive agents may be used in compositions contemplated herein. Examples of suitable anticorrosive agents include potassium hydrogen phosphate (CAS No. 7758-11-4) available from Rhodia (Cranbury, N.J.), potassium dihydrogen phosphate (CAS No. 7778-77-0), sodium nitrite, benzoic acid, and amino alcohols, such as one of the AMP series, for example AMP-95, available from Angus Chemical Company (Buffalo Grove, Ill.). Additional examples contemplated herein include cathodic protectors (available from Asbury Carbons), anodic protectors (available from Asbury Carbons), amines such as, for example, those disclosed in U.S. Pat. No. 5,707,733, incorporated by reference, phosphoryl esters, sodium phosphate salts, borates (such as sodium octaborate; available from MITSUI CHEMICALS AMERICA, INC), liquid phase inhibitors, and vapor phase inhibitors.
An ultraviolet light absorber can be added to a décor particle composition to, for example, improve ultraviolet resistance (for example, weatherability) of a cured finished product. Used in combination with antioxidants and/or heat stabilizers, the performance of ultraviolet absorbers can be further enhanced.
A wax may be added to a décor particle composition to, for example, control the gloss and/or flow of a cured décor product. A wax may also be used to add texturing to a cured décor product. Additionally, some wax additives may improve mar and scratch resistance of a cured décor product. Illustratively, a wax from a natural product, such as Carnauba wax, beeswax, or synthetic waxes, such as hydrocarbon compounds, halogenated hydrocarbons, and PTFE comprise a large percentage of waxes and may be used in the décor product and/or décor particle composition. Examples of wax additives include DT3329-1 (Ciba Geigy), Castor Wax, Powder Tex 61 (Shamrock Technologies, Inc.), Lanco® TF-1778 (available from Noveon Inc.), and Lanco® PP-1362D (available from Noveon, Inc.).
A silicone additive may also be added to a décor particle composition to improve, for example, mar and scratch resistance of a cured décor product. Although not wishing to be held by theory, it is believed that the silicone additives reduce the coefficient of friction that may affect, for example, intercoat adhesion in a two-coat system. Examples of silicone additives include polysiloxane and silicone oil.
Catalysts such as 2-Propyl imidazole may be added to a décor particle composition to, for example, accelerate cure speed, lower cure temperature, and/or improve physical and/or chemical properties of the cured product.
Texturing agents may be added to a décor particle composition to, for example, alter and/or manipulate the viscosity of the composition.
Electrical charge control additives may be added to a décor particle composition to, for example, control transfer efficiency. Examples include TINUVIN® 144 (Ciba Specialty Chemicals), barium titanate, and quaternary ammonium salts.
Electrical conductivity additives may be added to a décor particle composition to, for example, dissipate electrical charge in the composition and/or finished product. The electrical conductivity additives may be, for example, filler-like, pigment-like, or wax-like in nature. For example, an electrical conductivity additive contemplated herein includes Al2O3.
Processing aids may be added to a décor particle composition to, for example, facilitate processing of the composition. Processing aids are well known to those skilled in the art.
Colorants may be added to a décor particle composition to, for example, obtain a desired color. Illustrative pigments include organic and inorganic pigments, including, for example, titanium dioxide, iron oxide red, iron oxide yellow, iron oxide black, heat stabilized iron oxide, calcinated mixed metal oxide, diarylide, condensed disazo, and phthalo blue. Illustrative colorants and amounts that may be used individually or in combination in the décor product and/or décor particle composition are provided below in Table No. 8.
Numerous other organic and inorganic colorants known to those skilled in the art may be utilized in the compositions herein described.
A filler may also be added to a décor particle composition. Two illustrative fillers include calcium carbonate and barium sulfate (CaCO3 and BaSO4, respectively, both manufactured by Fisher Chemicals). The calcium carbonate fillers added to the décor product and/or décor particle compositions may, for example, reduce gloss, as well as the flow of an applied finish at higher concentrations. Wollastonite-type fillers may also be utilized as fillers in the décor product and/or décor particle compositions. Talcum, clay, dolomite, and magnesium-aluminum-silicate in powder form, usually ground to 1-10 microns average particle size, or micron sized glass beads, may also be used as fillers to obtain specific properties, such as, for example, corrosion resistance, gloss control, and/or film texture. Further, alumina may be added as an antistatic agent
Further, fillers, clays, and gums may serve as rheology modifiers by aiding in the stabilization of particle suspensions, as well as in the flow properties of such suspension, as is known in the art. Examples of clays contemplated include, for example, those described in U.S. Pat. No. 7,288,585. Additional examples include Veegum® granules, Bentone clays, and silica thickeners. One possible example of suitable Veegum® granules is Veegum® D granules available from R. T. Vanderbilt Company, Inc. (Norwalk, Conn.). Additional examples contemplated for use herein include smectite clays, for example, the Laponite series, available from Southern Clay Products, Inc. (Gonzales, Tex.). Suitable Laponite grades include Laponite B, D, DF, J, RS, RDS, S, 5482, XLG, XLS, and XL21.
Illustrative gums and appropriate substitutes contemplated for use herein include xanthan gum, guar gum, carboxy methyl cellulose, hydroxylethyl cellulose, Acrysol thickener products available from Rohm & Haas (Philadelphia, Pa.), polyacrylic polymers, and polyvinyl alcohol, and the like. An example of a suitable xanthan gum contemplated for use herein is Kelzan® HP, available from CP Kelco (San Diego, Calif.).
Additional rheology modifiers contemplated herein include cellulosics, hydrophobically modified ethoxylated urethanes (huers), surfactant gels, polyesters, and polysaccharides, such as chitins.
Illustratively, a décor product is applied to a surface to achieve a film thickness of about 0.004 mils to about 2.2 mils (about 0.01 microns to about 56 microns) upon curing or affixing the décor product, or to achieve coverage of about 0.02 to about 0.1 g dry décor product per square inch of surface, such as a carpet.
A décor particle formulation such as those embracing low temperature cure epoxy chemistry, low temperature cure epoxy-polyester hybrid chemistry, low temperature cure polyester-TGIC chemistry, low temperature cure PRIMID® chemistry, and low temperature cure polyurethane chemistry may be prepared in accordance with the following general processing procedure.
Formulation constituents are dry mixed either through low-intensity tumble-mixing or through high-intensity dry-blending performed in a mixer containing a vertical or horizontal mixing shaft with blades rotating at 50-1,000 rpm. Formulations are low-intensity tumble-mixed for about 5 to about 20 minutes, for example, or high-intensity dry-mixed for about 1 to about 5 minutes, for example, depending on batch size. Mixing serves to homogenize the active chemical ingredients and to disperse inert ingredients for enhanced color consistency and to avoid protrusions in applied films. Batch sizes may range from quarts to kiloliters in size. After dry-blending, the temperature of the mixture is maintained at or below about 40° C. to prevent lumping or meltdown.
The mixtures are extruded within minutes to hours after dry-mixing. Single screw extruders with reciprocating screw shaft movements, also called co-kneaders, and twin screw extruders with co-rotating screw shafts are suitable extruders, as well as planetary extruders, counter-rotating twin screw extruders, or single screw extruders. Illustrative extruder size ranges from table-top laboratory models with 10-30 mm screw diameters and 1-5 kg per hour theoretical outputs to production models with 30 to over 300 mm screw diameters and 100 kg to over 2,000 kg per hour theoretical outputs.
The extruders for processing may be heated via water, oil, or electrical heat jacket located on the outside of the extruder barrels. Extruder barrel processing temperatures may range from about 70° C. to about 125° C., though temperatures outside this range may be used to achieve desired properties in some applications. Some extruder barrel heaters utilized in the powder processing may be segmented, in which case, the premix intake zone of the extruder may be run cold or at a minimal heat of about 40° C. to about 50° C. Depending on extruder and screw design, a barrel heat of about 100° C.±15° C. is adequate for processing highly-reactive, low temperature cure powder coating formulas. The screws may have a helical section in the premix intake area and “paddle” sections for dispersing and melt-mixing the extrudate. Residence time of the extrudate within the extruder typically does not exceed about 60 seconds. The production extruders used for processing the powder coatings are run between about 50 and about 750 rpm screw speed. Screw speeds and extruder barrel temperatures are selected to obtain between about 50% to about 90% torque. Extrudate temperatures range from about 100° C. to about 125° C. as a result of extruder barrel heat and frictional heat from the rotating screws. The extrudate is immediately cooled after exiting the extruder to solidify the material for further processing and to arrest chemical reactions. The extrudate is gravity-fed into counter-rotating chill rolls set about 1.5 to about 3 mm apart. The resulting extrudate sheet is transported on a cooling belt to a flaker or crusher unit where the sheet is broken into flakes under about 1 inch square in size. Cooling belt temperatures from about 5° C. to about 35° C. are maintained during processing. The resulting flakes are milled and characterized using air classifying mills (ACM), cyclones, and sieves, to determine particle size distributions and mean particle sizes. Illustratively, a particle size distribution for a décor particle ranges from about 90% by volume or more of the particles having a size less than about 100 microns, or less than about 25 microns, or less than about 10 microns, or from about 0.1 to about 50 microns, or from about 1 to about 20 microns, or from about 3 to about 10 microns, or from greater than about 750 nm to about 100 microns. Further examples of particle sizes include particles from about 20 to about 80 microns, or from about 25 to about 75 microns, or from about 30 to about 70 microns, or from about 35 to about 75, or from about 40 to about 60 microns, or from about 40 to about 80 microns, or about 40 to about 50 microns, or from about 50 to about 60 microns in size, or about 40 microns, or about 45 microns, or about 50 microns, or about 55 microns, or about 60 microns, or larger or smaller particle sizes depending on the desired application. All equipment is purged after processing different formulas or colors to avoid chemical or color cross-contamination.
An emulsified décor product may be prepared in accordance with the following general processing procedure. In a one-gallon glass container, initially an emulsifier is added to a powder, such as a NATURA™ toner and/or a décor particle and mixed to thoroughly coat the powder with the emulsifier. Water is then added to the powder and emulsifier mixture and is blended using an IKA-Werke Eurostar power basic mixer at a speed of about 750 rpm for about 4 hours. Additional additives may be added if so desired at any point during preparation of the décor product. After the 4 hour blending period, the mixture is further mixed by continuously mixing at room temperature on a magnetic stir/heat plate (Isotemp #409N0063 available from Fisher-Scientific) with a 2-inch magnetic stir bar at 100 rpm for an additional 24 hours. Illustratively, an emulsified décor product composition may include the following constituents as shown below in Table No. 9.
Similarly, a rheology modifier-containing composition may be formulated using a procedure similar to that described below.
A rheology modifier-containing composition may include the following constituents as shown below in Table No. 9a.
For example, a rheology modifier-containing composition may include, for example, about 0.12 to about 0.3% by weight of a thickener, about 0.05 to about 0.1% by weight of a gum, about 1.0 to about 1.5% by weight of a clay, about 0.1 to about 0.75% by weight of a sodium dioctyl sulfosuccinate, about 0.75 to about 1.25% by weight of propylene glycol, about 0.1 to about 1% by weight of an anticorrosive agent, about 0.1 to about 0.5% by weight of a biocide, substantially homogeneous particles including a colorant and a resin, and a liquid carrier.
The present disclosure is further illustrated by the following examples, which should not be construed as limiting in any way. Unless otherwise stated, all percentages recited in these examples are weight percents based on total specified composition weight.
The décor particle compositions of examples 1-24 were prepared using the general processing procedure described above by blending (mixing) and processing the constituents on a 19 mm APV laboratory twin screw extruder (Model No. MP19TC-25, manufactured by Baker Perkins) with co-rotating screws at 100° C. barrel temperature, 400 rpm screw speed, and 50% to 90% torque. The extrudate was cooled on chill rolls that resulted in 3/32 inch (about 3 mm) thick solid extrudate sheets. The sheets were broken into flakes no larger than 1 square inch (6.45 cm2) in size. The flakes may be ground on air-cooled jet mills and classified to a particle size range of about 0 microns to about 80 microns, or larger.
The following steps are taken to achieve a specific size range, such as, for example from about 40 to about 60 microns. The resulting particle powder from the above procedure is first dry sieved through a 60 micron sieve, and the pass through is collected, thus removing anything above 60 microns. The second step is to dry sieve the pass through using a 40 micron sieve, and discarding the pass through, to eliminate relatively large particles that are smaller than 40 microns in size. In the final step, a slurry of the remaining particles is made in water and then strained through a 40 micron filter cloth to remove any small particles attached to large particles. The particles may then be used to prepare décor product compositions, such as those described herein.
The décor products of examples 25-28 were prepared using the general processing procedure described above by mixing the décor particle or toner and emulsifier for a period of time until the décor particles or toner were coated with the emulsifying agent or agents. Water was then added and thoroughly mixed as described above.

The décor product from Table No. 51 utilizing the PRIMID® Bay Blue particle of Example 25 was mixed according to the following methodology. The batch size was adjusted to 400 g. A 600 mL beaker was loaded with about 128 g (35% of the total water available) of deionized water. The Veegum® granules were added to the beaker and mixed for about 2 to about 3 hours. Propylene glycol, Aerosol OTS, Acticide® MBL 5515, potassium hydrogen phosphate, and potassium dihydrogen phosphate were added to the beaker and mixed for about 15 minutes. The Primid® Bay Blue particle made according to Example 25 was added and mixed for about 15 minutes. The Kelzan® HP was added and mixed for about 1 to about 2 hours. The Lyoprint® PTU-US was added and mixed until it was substantially dissolved, which was about 2 hours to about 3 hours. The remaining about 238.68 g (65% of the total water) deionized water was added.
The décor products of Example 42 are tested for their ability to be applied to a nylon test carpet, removed (reversibility) from the nylon test carpet prior to an affixation step, affixed to the nylon test carpet using heat as the energy source, and their durability after affixation to the nylon test carpet. The following may be performed for each formulation of Example 39 to test reversibility, affixation, and durability thereof.
A décor product of Example 42 is thoroughly mixed and placed into an 8 oz. PET bottle with finger pump fine mist sprayers having an output of 60 micron particle size (N2862524410WHT3, bottle neck—24/410; available from ebottles.com, Inc.) or other suitable dispenser, such as an aerosol container with a mesh filter and a propellant, described above. A two-foot by two-foot piece of nylon test carpet is vacuumed using a Bissell CLEANVIEW® II vacuum cleaner manufactured by Bissell Homecare, Inc. to remove loose fibers and dirt. The specifications of the nylon test carpet utilized are indicated in Table 52.
The baseline color of each of three spots over which the décor product is applied is determined using a Minolta data processor model No. DP-301 combined with a Minolta model No. CR-310 chroma meter (both manufactured by Konica Minolta Sensing Americas, Inc.) that is set to the “L-a-b” setting to record A E (color change) and calibrated according to the manufacturer's instructions.
The following tests are performed separately for each of the décor products of Example 42. Prior to application of the décor product, a stencil, disclosed in Attorney Docket No. 4968, was centered on the surface of the nylon test carpet sample. Subsequently, the décor product is applied as a gentle mist to the nylon test carpet from the finger sprayer at distance of 8-10 inches from the nylon test carpet and at a rate to saturate the top surface of the nylon test carpet. The applied décor product is allowed to dry overnight at ambient temperature and humidity on the nylon test carpet. Once dried, one half of the applied décor product pattern is removed from the nylon test carpet using a Shop-Vac® 1x1® wet/dry vacuum with hose attachment (1¼ inch diameter×4 feet). The vacuum characteristics include 1 peak horsepower, 115 cubic feet/minute of air flow, 52 inches of sealed pressure, and electrical ratings of 120 V, 60 Hz, and 5.5 A. The pattern is vacuumed twenty times in one direction and then twenty times in the opposite direction over the same area. Once vacuumed, L-a-b measurements are taken from the vacuumed areas of the nylon test carpet with the Minolta data processor and Minolta chroma meter.
The un-vacuumed décor product pattern is subsequently affixed on the nylon test carpet by placing an absorbent paper towel (WYPALL® X60 reinforced wipes from Kimberly-Clark Corp.) over the décor product pattern and heating the décor product pattern using a household iron (Hamilton-Beach Model #14340) set at the highest setting (cotton). Heat is applied through the absorbent paper towel in a circular motion for 2½ minutes per square ft of décor product. Subsequently, the paper towel is removed from the nylon test carpet and L-a-b values are measured on the affixed décor product pattern using the Minolta data processor and Minolta chroma meter specified above.
To determine the resilience of the affixed décor product on the nylon test carpet, one half of the affixed décor product is vacuumed twenty times (using a back and forth motion) with a Shop-Vac® 1x1® wet/dry vacuum with hose attachment. The L-a-b values of the vacuumed and affixed versus the affixed-only (unvacuumed) areas are taken using a Minolta data processor combined with a Minolta chroma meter as mentioned above.
Approximate expected measures of reversibility, affixation, and durability of décor products of Example 42 are shown below in Table No. 53. The values indicated in Table No. 53 are believed to be representative of results that would be measured for any of the décor product compositions described herein.
The Décor Bay Blue particle of Example 25 was processed and filtered using a mesh screen to achieve the noted particle size distribution in Table No. 54. The Bay Blue particle was added to the décor product according to the methodology of Example 39. The resulting décor product was mixed in a trigger actuated container and applied to the nylon test carpet described in Example 39 above, with the below modifications. The number of spray strokes utilized in the application is indicated in Table No. 54. The décor product was substantially dried affixed and vacuumed according to the method in Example 43, and subjectively measured for reversibility, where a rating of N/R indicated that the décor product was not acceptably reversible and where a rating of R indicated that the décor product was acceptably reversible.
Tg and Tm of surface substrates were measured using a Model Q100 Differential Scanning Calorimeter (TA Instruments, Inc.) at a heating rate of 20° C./min. Specifically, in this way, the nylon carpet of Table No. 52 was measured to have a Tg of 40-45° C. and a Tm of 257° C. Further, a polyester carpet of Table No. 52 was measured to have a Tg of 140-150° C. and a Tm of 247° C.
The décor product of Example 42 was tested for its ability to be affixed to the nylon test carpet of Table No. 52, using a sealant mixture of Table No. 55, and the durability thereof after affixation to the nylon test carpet.
A décor product of Example 42 is thoroughly mixed and placed into an aerosol dispenser available from Ball as 211×713 N.I. DOT-2Q IL-30. The aerosol dispenser has a valve assembly available from Summit (Summit SV-77 with a 2×0.020 stem, a 0.062 RE Body, a 0.023 spring, and a 0.050 Buna gasket in a laminated cup. An actuator that fits onto the valve assembly is a basic vertical actuator (AX-14032) with a 70178-2402 insert orifice size of 0.018×0.044). The aerosol dispenser was pressurized to 120 psi using nitrogen gas. A two-foot by two-foot piece of nylon test carpet was vacuumed using a Bissell CLEANVIEW® II vacuum cleaner manufactured by Bissell Homecare, Inc. to remove loose fibers and dirt.
The following tests were performed separately for the décor product of Example 42. Prior to application of the décor product, a stencil, disclosed in application Ser. No. 12/152,405 was centered on the surface of the nylon test carpet sample. Subsequently, the décor product was applied as a gentle mist to the nylon test carpet from the aerosol dispenser at distance of about 8-10 inches from the nylon test carpet and at a rate to saturate the top surface of the nylon test carpet. The applied décor product was allowed to dry for about 16 hours at ambient temperature and humidity on the nylon test carpet.
Once dry, the décor product pattern was subsequently affixed on the nylon test carpet by applying a sealant composition according to Table No. 55 below.
The sealant composition was prepared by mixing the constituents of Table No. 55 in a beaker and adding the mixture to the same kind of aerosol dispenser disclosed above. The aerosol dispenser containing the sealant composition was pressured to 120 psi using nitrogen gas. Subsequently, the sealant composition was applied as a gentle mist to the nylon test carpet from the aerosol dispenser at distance of about 4-5 inches from the nylon test carpet and at a rate to saturate the top surface of the nylon test carpet. The sealant was allowed to dry for approximately 24 hours.
To determine the color retention of the affixed décor product on the nylon test carpet, the affixed décor product was vacuumed twenty times in two different directions (using a back and forth motion) with a Bissell model 3576-6 12 amp upright vacuum cleaner. After drying and vacuuming, the décor product was subjectively evaluated for color retention. A subjective scale of 1 to 10 was used, where a score of 1 signified a décor product that had the worst, or little to no color retention, and a score of 10 signified a décor product that had the best, or substantially all color retention.
Approximate measures of color retention of décor products of Example 42 and the sealant composition from Table No. 55 are shown below in Table No. 56. The values indicated in Table No. 56 are believed to be representative of results that would be measured for any of the décor product compositions made according to Table 51.
To determine the suitability of various solvent compositions, characteristics of the compositions were evaluated including décor product sealing, appearance, foaming upon application, and resoiling of treated areas. Certain sealant formulations were formulated to contain one or more of ethanol, isopropanol, and acetone to decrease drying time. Another strategy for decreasing dry time was using solvents with lower boiling point/higher evaporation rates. Some formulation variability was introduced by addition of more or less than 10% of solvent or the addition of high (e.g., 20%) drying-solvent (acetone, ethanol, isopropanol) concentrations. After formulation of the sealant compounds, visual observations were made about 12-24 hours after mixing to determine appearance. A uniform single phase solution with watery appearance was desired to ease of production of the product and provide consistent spray performance throughout the life of the applicator (for example, an aerosol can).
Sealant performance on carpets was evaluated using a series of four 7×7 circles created using a template, each circle contained 7 grams of colorant formula “DOL2” dispensed from an aerosol container. Two carpet types were used for these experiments and are described below in Table 57. A generic colorant formulation is shown below in Table 58. Several different colors were applied during the experimental process. It was discovered that several colors exhibited low smearing, and other colors were more prone to smearing. Smearing prone colors included Pink, Rust, and Burgundy with which the majority of sealing tests were performed.
Sealant compositions were applied in two 3.5 gram doses, 30 minutes apart. Foaming was evaluated with a target of achieving ½″ of foam per 3.5 gram application to indicate the proper amount of sealant applied. After the second application, the sealant composition was allowed to dry between 24 to 48 hours. After drying, the circles treated with sealant were vacuumed, using a procedure that included 50 strokes (each stroke back and forth across all four colored circles) with a vacuum. The vacuum model used was “Bissell Cleanview II Bagless Plus” made by Bissel (Grand Rapids, Mich.). Sealing performance was evaluated only after the vacuuming step. Three criteria were evaluated to determine sealing performance including color intensity, smearing, and crustiness/feel (for example, agglomeration of décor particles of those retained on carpet tufts). In one embodiment, a sealant would coat each fiber in the carpet tuft evenly, exhibit little or no smearing, and yield a vibrant color that is resistant to vacuuming.
Resoiling properties of the sealant compositions were evaluated by applying reasonable amounts of sealant to uncolored carpeting (such as about 1 g/in2) on Carpet B (see above), and allowing the treated carpets to dry for 48 hours. The treated carpets were placed in high traffic walkway areas in our laboratory, and discoloration of the treated areas was evaluated informally over a two week period.
A subset of sealant compositions evaluated included single solvents. These sealant formulations provided information pertaining attributable to the sole solvents included therein. Table 59 below summarizes the solvents that were investigated, along with their water solubility, observed solubility in the sealant composition, an evaluation of their individual effectiveness as sealants (at 10% concentration), and reference to the formula in which the solvent was present at 10%, with no other solvents.
The sealant compositions evaluated are listed in Table 60 below.
The results of seal quality, foaming quality, durability of the set color as determined by the heel test (grinding the heel of a shoe through about 40 degrees of an arc 10 times on the set color), and the period of drying time before vacuuming (50 strokes) to determine the seal quality are indicated for the sealant compositions of Table 60 are indicated below in Table 61.
At the concentrations and mixtures used for the sealant compositions noted above in Table No. 60, the following generalizations and observations were found that may or may not apply at other concentrations or with other mixtures not tested herein.
When added to sealant compositions, ethanol, isopropanol, and acetone primarily served as drying aids but also improved solubility of otherwise insoluble solvents. However, they also diminished foaming efficacy. Acetone further seemed to diminish the sealing efficacy of active solvents.
Higher alcohols (benzyl and diacetone alcohol), and ketones (cyclohexanone and diisopropyl ketone) were not found to impart any notable benefits. In contrast, ethylene glycol hexyl ether and ethylene phenyl ether (EPH) were both good active solvents. Though, EPH was found to be conducive to resoiling. Ethylene glycol hexyl ether inhibited foaming. Of diethylene glycol methyl, ethyl, and propyl ethers, the methyl and ethyl ethers had modest sealing activity. Diethylene glycol propyl ether (DP) was found to have very good sealing activity and had good foaming action. In general, these diethylene glycol ethers have relatively low toxicity exposure limits, and increasing the level above 3% is unlikely to yield a satisfactory toxicity profile.
Propylene glycol methyl and n-butyl ether were found to have modest sealing activity. Dipropylene glycol methyl ether exhibited reasonable sealing activity, but also imparted a noticeable film on top of the carpet after application and only allowed a less desirable foam. Dipropylene glycol dimethyl ether (DMM) was not very active at sealing on its own, however, it is believed to aid in evaporation of the higher boiling EPH and DPNB solvents. In addition, DMM helped to bring EPH into solution, above its solubility limit in water. On the other hand, DMM was found to produce grey resoiling.
Dipropylene glycol n-butyl ether (DPNB) was found to be an active solvent, but by itself, it did not have ideal foaming activity. However, in combination with modest amounts of DP, DPNB yielded good sealing activity with good foaming. Additionally, resoiling does not appear to be a serious issue for the blend.
Several of the acetate esters considered (for example, EGDA to Dowanol DPMA) exhibited excellent performance properties. However, it was determined that this class of materials may undergo slow hydrolysis reactions in aqueous solution, thereby degrading to the parent alcohol and acetic acid. Such reactivity is undesirable and could prove problematic in any commercial formulation by 1) failing to adequately seal and 2) lowering the pH of the formulation to levels that could compromise the stability of the formula in an aluminum container.
Tri(butoxyethyl)phosphate (TBEP) was found to be a powerful active sealant. However, it had the highest boiling point of all solvents considered and was found to be a strong resoiler and produced a substantial smearing effect, when used as a sealant. Also, at a 1% concentration it destroyed foaming action in otherwise good foaming blends.
