Additional features and advantages will be set forth in the detailed description which follows, and, in part, will be readily apparent to those skilled in the art from the description or recognized by practicing the embodiments as described in the written description and claims thereof, as well as the appended drawings. It is to be understood that both the foregoing general description and the following detailed description are exemplary.
The accompanying drawings are included to provide further understanding and are incorporated in and constitute part of the specification. The drawings illustrate one or more embodiments, and together with the description serve to explain the principles and operation of various embodiments.
Alternative exemplary embodiments relate to other features and combinations of features as may be generally recited in the claims.
This application will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements in which:
Referring generally to the figures, various embodiments of a permanent color-matched paint tape are shown. Embodiments of the tape discussed herein include an innovative layer composition design to provide for a variety of desired characteristics, including long-term adhesion to various surfaces, color matching to painted portions of a base surface, and texture matching to painted portions of a base surface. Traditionally, prior to painting a base surface, painter's tape is applied near an adjoining surface (trim, light switches, etc.) to protect the adjoining surface from being painted when painting near the interface of the base surface and adjoining surface. Typically, traditional painter's tape is removed after initially painting the base surface. Removal of traditional painter's tape can result in damaging paint underneath the painter's tape or require further touch-up painting near the edge of the tape covered surface. Applicant has found it beneficial to provide a paint tape that remains in place on the wall after painting the base surface and is configured to match the color and/or texture of the paint being applied to the base surface. This allows user to avoid unintentionally painting an adjoining surface by applying the paint tape to the base surface up to the interface of the base surface and adjoining surface, thereby only needing to paint the base surface up to the edge of the paint tape rather than up to the interface with the adjoining surface.

Throughout this document, peel adhesion strength is measured in accordance with the Pressure Sensitive Tape Council (PSTC) 101 International Standard for Peel Adhesion of Pressure Sensitive Tape Test Method A as applied to a glass surface. Peel adhesion strength is measured as the force in ounces per inch of width of the tape required to peel a tape away from a glass surface at a 180-degree angle and a rate of 5 mm/sec. Peel adhesion strength is measured after the tape has been applied to the glass surface for a 24-hour dwell period at 70 degrees Fahrenheit and 50% humidity.
In some embodiments, the first adhesive 10 provides the paint tape 2 with a peel adhesion strength that is at least 40 oz/in. The first adhesive 10 can provide the paint tape 2 with a peel adhesion strength of between 43 oz/in and 53 oz/in. In a specific embodiment, the first adhesive 10 provides the paint tape 2 with a peel adhesion strength that is at least 48 oz/in. In another embodiment, the first adhesive 10 provides the paint tape 2 with a peel adhesion strength of between 12 oz/in and 40 oz/in.
As shown in
The first adhesive 10 adheres the paint tape 2 to removable coversheet 16 such that less force is required to peel paint tape 2 away from removable coversheet 16 than the peel adhesion strength of paint tape 2. In various embodiments, the force required to peel paint tape 2 away from removable coversheet 16 when measured under PSTC 101 Test Method A as applied to removable coversheet 16 (“the coversheet peel strength”) is less than 40 ounces of force per inch width of paint tape 2. In a specific embodiment, the coversheet peel strength of paint tape 2 is less than 30 ounces of force per inch width of paint tape 2. In another embodiment, the coversheet peel strength of paint tape 2 is less than 12 ounces of force per inch width of paint tape 2.

Coating 14 is configured to provide at least a portion of the second side 8 of paint tape 2 with a tape color that is the same color as a paint color of the paint 20. A portion of the second side 8 of paint tape 2 has a surface area of at least one square inch. Throughout this document, color is measured as CIELAB coordinates. CIELAB coordinates include a lightness value, L*, measured on a scale from 0-100, wherein 0 represents black and 100 represents white, a green-red value, a*, wherein negative values indicate green color and positive values indicate red color, and a blue-yellow value, b*, wherein negative values indicate blue color and positive values indicate yellow color. A first color is the same as a second color if the ΔE (“Delta E”) value between the CIELAB coordinates of the first color and the second color is less than or equal to 10. The ΔE value is defined by the following equation, commonly referred to as the CIE76 color difference formula:
wherein (L1*, a1*, b2*) represents the CIELAB coordinates representing the first color and (L2*, a2*, b2*) represents the CIELAB coordinates of the second color.
According to an exemplary embodiment, the ΔE value between the tape color of the paint tape 2 and the paint color of the paint 20 is less than or equal to 20. Additionally, the ΔE value between the tape color of the paint tape 2 and the paint color of the paint 20 can be less than or equal to 10, such that the tape color and the paint color are the same color. In a specific embodiment, the ΔE value between the tape color of the paint tape 2 and the paint color of the paint 20 is less than or equal to 5. In another embodiment, the ΔE value between the tape color of the paint tape 2 and the paint color of the paint 20 is less than or equal to 2.
Throughout this document, texture is measured as arithmetic average roughness (Ra) of a surface. An Ra value is a mean of the absolute deviation from a mean line of the profile of a surface as measured over a 0.01-inch length of the profile. The mean line of a profile of a surface is a line corresponding to the average location of the profile with respect to deviations of the profile in a direction perpendicular to the surface. A first surface has the same texture as a second surface if an average Ra value of the first surface is within a 10 percent range above or below an average Ra value of the second surface. An average Ra value of a surface is the mean of Ra values of adjacent segments of a profile of the surface that span the entire profile.
Coating 14 is configured to provide at least a portion of the second side 8 of paint tape 2 with a tape texture that is the same texture as a paint texture of the paint 20, once the paint 20 has dried on the base surface 1. According to an exemplary embodiment, an average Ra value of the paint tape 2 is within 20 percent of an average Ra value of dried paint 20 on base surface 1. Additionally, an average Ra value of paint tape 2 can be within 10 percent of an average Ra value of dried paint 20 on base surface 1 such that paint tape 2 has a same texture as paint 20. In a specific embodiment, an average Ra value of the paint tape 2 is within 5 percent of an average Ra value of dried paint 20 on base surface 1. In another embodiment, an average Ra value of the paint tape 2 is within 2 percent of an average Ra value of dried paint 20 on base surface 1.
Coating 14 can also be configured to provide at least a portion of the second side 8 of paint tape 2 with a tape surface having the same coefficient of static friction as a paint surface of the paint 20, once the paint 20 has dried on the base surface 1. According to an exemplary embodiment, a coefficient of static friction of the paint tape 2 is within 20 percent of a coefficient of static friction of dried paint 20 on base surface 1. Additionally, a coefficient of static friction of paint tape 2 can be within 10 percent of a coefficient of static friction of dried paint 20 on base surface 1. In a specific embodiment, a coefficient of static friction of the paint tape 2 is within 5 percent of a coefficient of static friction of dried paint 20 on base surface 1. In another embodiment, a coefficient of static friction of the paint tape 2 is within 2 percent of a coefficient of static friction of dried paint 20 on base surface 1.

A paint tape 2 is generated for applying to a building surface prior to painting with an architectural paint having a paint color and a paint texture and for remaining in place after completion of the painting by first selecting a coating 14. The coating 14 is applied to a casting web. The casting web is a substrate used to generate the paint tape 2 on, from which the paint tape 2 can later be removed. The casting web can include a release-coated fabric, plastics, paper, silicone, or any other material suitable for generating paint tape 2 on and later removing paint tape 2 from. The coating 14 is cured. The coating 14 can be cured by air-drying, convection with heated air, infrared heating, UV radiation exposure, or electron-beam processing.
The cured coating 14 is compared to the architectural paint to determine if the cured coating has the same color as the paint color. If the color of coating 14 is not the same color as the paint color, then the process of selecting a coating 14, applying the coating to the casting web, and comparing the color of the coating to the paint color is repeated until the color of the coating 14 and the paint color are the same. If the color of coating 14 and the paint color are the same, then the coating 14 is combined with a transfer adhesive and the combination of the coating 14 and the transfer adhesive is removed from the casting web.
In an exemplary embodiment, the cured coating 14 is also compared to the paint to determine if the cured coating 14 has a coating texture that is the same texture as the paint texture. If the coating texture is not the same texture as the paint texture, then the process of selecting a coating 14, applying the coating to the casting web, and comparing the texture of the coating to the texture of the paint is repeated until the texture of the coating 14 and the paint texture are the same. If the texture and color of coating 14 are the same as the paint texture and the paint color, then the coating 14 is combined with the transfer adhesive and the combination of the coating 14 and the transfer adhesive is removed from the casting web.
The transfer adhesive includes substrate sheet 4 having first side 6 and second side 8. The transfer adhesive also includes first adhesive 10 on first side 6 of substrate sheet 4 and removable coversheet 16 applied to first adhesive 10. Transfer adhesive also includes interface adhesive 12 on second side 8. In a specific embodiment, interface adhesive 12 adheres coating 14 to the transfer adhesive. Coating 14 can include the paint having the paint color compared to the color of the coating 14. The paint can be paint 20.
The combination of the transfer adhesive and the coating 14 can be transported or shipped to a location that is distinct from the location where the transfer adhesive and coating 14 were combined. In an exemplary embodiment, the transfer adhesive and coating 14 is combined at a factory or manufacturing facility and shipped to a retail store, wholesaler, warehouse, other factory or manufacturing facility, or third-party place of business or residence.
