The present technology relates to a wide temperature water borne sealant for use in connection with a water-based latex sealant that can be applied at low temperatures to replace the use of solvent based sealants.
The use of solvent or water based sealants is known in the prior art. These solvent based sealants are made with solvents that may be toxic, and in some instances, the solvents used may be carcinogenic (as is the case for tert-butyl acetate). In addition increased government regulation and heightened consumer awareness has put increased pressure on the manufacturers of solvent based sealants to reduce the volatile organic compound (VOC) content in the products.
A problem that has persisted for the development of water-based formulations for low temperature sealant applications has been the inability of the sealant to maintain adequate physical properties (rheology and viscosity) while still curing at temperatures below the freezing point of water (0° C./32° F.).
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe an wide temperature water borne sealant that allows a water-based latex sealant that can be applied at low temperatures to replace the use of solvent based sealants.
Therefore, a need exists for a new and novel wide temperature water borne sealant that can be used for a water-based latex sealant that can be applied at low temperatures to replace the use of solvent based sealants. In this regard, the present technology substantially fulfills this need. In this respect, the wide temperature water borne sealant according to the present technology substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an composition primarily developed for the purpose of a water-based latex sealant that can be applied at low temperatures to replace the use of solvent based sealants.
In view of the foregoing disadvantages inherent in the known types of solvent based sealants now present in the prior art, the present technology provides a novel wide temperature water borne sealant composition, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present technology, which will be described subsequently in greater detail, is to provide a new and novel wide temperature water borne sealant and method which has all the advantages of the prior art mentioned heretofore and many novel features that result in an wide temperature water borne sealant which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
According to one aspect of the present technology, the latex sealant composition essentially includes at least one latex polymer, at least one freeze thaw stabilizer, and at least one peptone or at least one additive derived from a peptone.
According to another aspect of the present technology, the latex sealant composition essentially includes at least one defoamer, at least one latex polymer, at least one biocide, at least one surfactant, at least one freeze thaw stabilizer, at least one dispersing aid, at least one enzymatic hydrolysate peptone or at least one additive derived from an enzymatic hydrolysate peptone, at least one pigment, at least one filler, and at least one thickener.
According to yet another aspect of the present technology, the latex sealant composition essentially includes at least one water-based and non-silicone antifoam agent, at least one acrylic latex polymer with a Glass Transition Temperature (Tg) of 0° C. or less, Mergal® 758, Polyphase® 678, octylphenol ethoxylate, propylene glycol, tripolyphosphate or tetrapotassium pyrophosphate, collagen peptide, at least one pigment, ground marble, and a polyacrylate thickener.
According to yet another aspect of the present technology, the latex sealant composition essentially includes HL-52, Rhoplex™ 4400, Mergal® 758, Polyphase® 678, Triton™ x405, propylene glycol, potassium tripolyphosphate (KTPP) or Tetrapotassium pyrophosphate (TKPP), gelatine hydrolysate enzymatic, W-7016 Black, Tamol™ 851, Drikalite®, and Paragum® 500.
There has thus been outlined, rather broadly, features of the present technology in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
Numerous objects, features and advantages of the present technology will be readily apparent to those of ordinary skill in the art upon a reading of the following detailed description of the present technology, but nonetheless illustrative, embodiments of the present technology when taken in conjunction with the accompanying drawings.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present technology. It is, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present technology.
It is therefore an object of the present technology to provide a new and novel wide temperature water borne sealant that has all of the advantages of the prior art solvent based sealants and none of the disadvantages.
It is another object of the present technology to provide a new and novel wide temperature water borne sealant that may be easily and efficiently manufactured and marketed.
An even further object of the present technology is to provide a new and novel wide temperature water borne sealant that has a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such wide temperature water borne sealant economically available to the buying public.
Still another object of the present technology is to provide a new wide temperature water borne sealant that provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Even still another object of the present technology is to provide an wide temperature water borne sealant for a water-based sealant that can be applied at low temperatures to replace the use of solvent based sealants. This allows for a water-based latex sealant that can be applied at low temperatures. The sealant not only remains pliable at low temperatures making it ideal for applications that require flexibility at low temperatures its' rheology and viscosity are such that it can be applied at temperatures below 0° C.
These together with other objects of the present technology, along with the various features of novelty that characterize the present technology, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the present technology, its operating advantages and the specific objects attained by its uses, reference should be made to the accompanying drawings and descriptive matter in which there are illustrated embodiments of the present technology.
The present technology relates to embodiments of an wide temperature water borne sealant composition formulated with a latex emulsion that has a Glass Transition Temperature (Tg) less than or equal to 0° C., preferably less than or equal to −20° C., and an additive derived from an enzymatic hydrolysate peptone.
The present disclosure describes a water-based latex sealant that can be applied at low temperatures. The sealant can remain pliable at low temperatures making it ideal for applications that require flexibility at low temperatures its' rheology and viscosity are such that it can be applied at temperatures below 0° C.
The present technology composition is formulated with a latex emulsion that has a Tg less than or equal to 0° C., preferably less than or equal to −20° C., and an additive derived from an enzymatic hydrolysate peptone. The low Tg latex assures that the sealant will remain permanently flexible and non-tacky when cured, and the peptone provides the sealant with the means to prevent the water from freezing down to approximately −20° C.
The present technology composition can include at least one defoamer, a low Tg Latex Polymer, a biocide, a surfactant, a freeze thaw stabilizer, a dispersing aid, an enzymatic hydrolysate peptone, a pigment, a dispersing agent, a filler and a thickener.
1. Defoamers
In one embodiment of the present technology, the composition can include at least one defoamer or anti-foaming agent. Defoamers or anti-foaming agents are chemical additives that reduce and hinder the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer can be used interchangeably. Commonly used defoaming agents are insoluble oils, polydimethylsiloxanes and other silicones, certain alcohols, stearates and glycols. The defoamer is used to prevent formation of foam or is added to break foam already formed.
In industrial processes, foams pose serious problems. They cause defects on surface coatings and prevent the efficient filling of containers. A variety of chemical formulae is available to prevent formation of foams.
An example of a water based defoamer that can be utilized in the present technology composition is antifoam HL-52 by Hangzhou Harmony Chemical Co., Ltd., which is a 100% mineral water-based non-silicone antifoam agent. Antifoam HL-52 is a non-silicone 100% active defoamer designed to be as effective as silicone-based defoamers.
Optional examples of defoamers that can be utilized in the present technology include, but not limited to, Alkyl poly acrylates, Castor Oil, Fatty Acids, Fatty Acids Esters, Fatty Acids Sulfate, Fatty Alcohol, Fatty Alcohol Esters, Fatty Alcohol Sulfate, Foot Olive Oil, Mono & Di Glyceride, Paraffin Oil, Paraffin Wax, Poly Propylene Glycol, Silicones Oil, Vegetable & Animal Fats, Vegetable & Animal Fats Sulfate, Vegetable & Animal Oil, Vegetable & Animal Oil Sulfate, Vegetable & Animal Wax, Vegetable & Animal Wax Sulfate, AWABREAK G-109, AWABREAK PO-20, Alginates, salts of alginic acid, Andifoam DF 210FGK AB, Andifoam DF 220FGK AB, Andifoam DF 230FGK AB, Andifoam DFA 100M FGK AB, Andisil® EM 350 FGK AB, Andisil® EM 350C FGK AB, Blandol® White Mineral Oil, Carnation® White Mineral Oil, DOWSIL™ AFE-1520, DREWMULSE GMO (Glyceryl Monooleate), Durem™ 300, GLORIA® White Mineral Oil, GRINDSTED® Acetem 90-50, HopAid® Antifoam, I-MUL 300, I-MUL GMO, I-MUL GMO 40, I-MUL GMO K, I-MUL GMO—F, I-MUL PGE 32, I-MUL PGO 1010, I-MUL PGO 104, I-MUL PGO 31, KAYDOL® White Mineral Oil, KLEAROL® White Mineral Oil, Nu-FLOW®, Pinnacle™ 170 Petrolatum, Pinnacle™ 190 Petrolatum, Pinnacle™ 225 Petrolatum, Pinnacle™ LC 170 Petrolatum, Pinnacle™ LC 190 Petrolatum, Pinnacle™ LC 225 Petrolatum, Pinnacle™ WF 170 Petrolatum, Pinnacle™ WF 190 Petrolatum, Pinnacle™ WF 225 Petrolatum, Polyethylene Glycol 1000 NF, Polyethylene Glycol 200, Polyethylene Glycol 300, Polyethylene Glycol 3350 NF, Polyethylene Glycol 400 USP/NF/FCC, Polyethylene Glycol 4500 NF, Polyethylene Glycol 600 USP/NF/FCC, SILFAR® 1000, SILFAR® 350, SILFAR® 500, SILFAR® S 184, SILFAR® SE 4, SILRES® HK 46, XFO-100S, XFO-10S, XFO-20S, XFO-30S, XIAMETER™ ACP-1500, XIAMETER™ ACP-1920, XIAMETER™ AFE-0100, XIAMETER™ AFE-0300, XIAMETER™ AFE-1510, XIAMETER™ AFE-1520, oil based defoamers, powder defoamers, water based defoamers, silicone based defoamers, EO/PO based defoamers, alkyl polyacrylates, combinations thereof, and the like.
Oil based defoamers have an oil carrier. The oil might be mineral oil, vegetable oil, white oil or any other oil that is insoluble in the foaming medium, except silicone oil. An oil based defoamer also contains a wax and/or hydrophobic silica to boost the performance. Typical waxes are ethylene bis stearamide (EBS), paraffin waxes, ester waxes and fatty alcohol waxes. These products might also have surfactants to improve emulsification and spreading in the foaming medium.
Powder defoamers are in principle oil based defoamers on a particulate carrier like silica.
Water based defoamers are different types of oils and waxes dispersed in a water base. The oils are often mineral oil or vegetable oils and the waxes are long chain fatty alcohol, fatty acid soaps or esters.
Silicone-based defoamers are polymers with silicon backbones. These might be delivered as an oil or a water based emulsion. The silicone compound consists of an hydrophobic silica dispersed in a silicone oil. Emulsifiers are added to ensure that the silicone spreads fast and well in the foaming medium. The silicone compound might also contain silicone glycols and other modified silicone fluids.
Polydimethylsiloxane is a widely used antifoaming agent.
EO/PO based defoamers contain polyethylene glycol and polypropylene glycol copolymers. They are delivered as oils, water solutions, or water based emulsions.
Alkyl polyacrylates are suitable for use as defoamers in non-aqueous systems where air release is more important than the breakdown of surface foam. These defoamers are often delivered in a solvent carrier like petroleum distillates.
2. Low Glass Transition Temperature (Tg) Latex Polymers
In one embodiment of the present technology, the composition can include at least one latex or acrylic polymer/binder, preferably a low Tg polymer/binder. Polymers are composed of long, randomly entangled, chains of molecules. At low temperatures these chains are locked together and unable to move. The polymer feels hard and is relatively brittle. The addition of heat alters these molecular chains to become more mobile. Continuous application of heat makes the polymer more mobile, softer and more pliable. The temperature at which this happens is the “Glass Transition Temperature” or “Tg”. This transition is not at a specific temperature, but a range. The Tg is signified by a change in heat capacity. In other words, it absorbs heat but rather than getting hotter the material goes through this change of state.
The low Tg latex polymer utilizing in the present technology is sufficient to allow that the sealant will remain permanently flexible and non-tacky when cured. An example of a low Tg latex polymer that can be utilized in the present technology is Rhoplex™ 4400 or Rhoplex™ 2620 emulsions by Dow, which are 100% acrylic latex polymers designed to provide wide formulation latitude for caulks and sealants.
Typical Properties of Rhoplex™ 4400 Include:
Typical Properties of Rhoplex™ 2620 Include:
Optional examples of low Tg polymers that can be utilized in the present technology include, but not limited to, Rhoplex™ 2620 by The Dow Chemical Company (Dow), Polyvinylidene fluoride (PVDF), Polypropylene (PP atactic), Polyvinyl fluoride (PVF), Polypropylene (PP isotactic), Poly-3-hydroxybutyrate (PHB), styrene-butadiene copolymer, Nipol SB lattices, latex of acrylonitrile butadiene copolymer, acrylate latex, carboxylated styrene butadiene, non-carboxylated styrene butadiene, Styrene Acrylic Polymers, Rovene®, BarrierPro®, Tylac® and combinations thereof.
3. Biocide
In one embodiment of the present technology, the composition can include at least one biocide and/or preservative. Biocides can be a substance or additive that destroys or inhibits the growth or activity of living organisms, and as such can be used as preservative.
An example of biocides that can be utilized in the present technology are Mergal® 758 and/or Polyphase® 678 both by the Troy Corporation. Mergal® 758 is a formaldehyde-free, VOC-free, broad-spectrum preservative for waterborne systems. Polyphase® 678 is a zero VOC, water dispersed fungistat for aqueous based material. It can be appreciated that other and/or additional biocides can be utilized in place of the above described, and biocides used in the present technology may be an in-can preservative or suitable replacement.

5. Freeze Thaw Stabilizer
In one embodiment of the present technology, the composition can include at least one freeze thaw stabilizer/agent to depress the freezing point of the composition. Freeze-thaw agents depress the freezing point of a liquid by increasing the resistance to freezing. On thawing, the various volatile components reach maximum solubility at different times. The protective colloid will re-dissolve in the melting ice at different rates. If the cold flow occurs to the polymer particles before the protective agents become effective again, the system will remain in a flocculated or coagulated condition. The effective means of promoting freeze-thaw resistance also decreases the composition's over-all water resistance. Depressing the freezing point of the composition does increase the resistance to freezing by the discriminate use of the freeze thaw agent.
An example of surfactant that can be utilized in the present technology is propylene glycol (C3H8O2). Other names of propylene glycol can include propane-1,2-diol, α-Propylene glycol, 1,2-Propanediol, 1,2-Dihydroxypropane, Methyl ethyl glycol (MEG), and Methylethylene glycol. Propylene glycol is a synthetic organic compound, and chemically it is classed as a diol and is miscible with a broad range of solvents, including water, acetone, and chloroform.
