Embodiment 1

[0131] Example 1 - Spraying

[0132] Aluminum alloy substrates were sprayed with PPGEasyCoat and cured. The paint is iridescent. exist Figures 8a-8b A photo of the iridescent paint is illustrated in .

Embodiment 2

[0133] Example 2 - Brushrolled Substrate

[0134] Produces three cream-coloured painted aluminum alloy substrates. The first substrate was used as a control. A second substrate was coated with PPGEasyClean by brush roller and cured (passive coating). The second substrate was coated with PPGEasyClean by roller brush and cured (passive coating), followed by TOTOTHPC090402WC-A + THPC090402WC-B by roller brush and cured. Three substrates were tested for color and gloss change by exposure to a QUVA lamp for a period of 1000 hours. Such as Figures 9a-9b As shown, the gloss of the underlying color is only slightly reduced for the one-coat self-cleaning coating and the two-coat self-cleaning coating, while the difference in color change is negligible.

Embodiment 3

[0135] Example 3 - Roller Coating - Polyurethane Roller

[0136] Roll coating of various painted aluminum alloy substrates by means of guided roll coating lines. Systems for roller coating with Figure 5 Similar to that shown. Barrier coatings are applied over pigmented aluminum sheet products with a predetermined color and sheen. This barrier coating is converted into a barrier layer. A self-cleaning coating is then applied to the barrier layer, which is then converted into a self-cleaning layer. The roll coating conditions and wetting results are provided in further detail below. The produced colored self-cleaning substrate maintained the predetermined color and gloss of the aluminum alloy sheet product. Such as Figures 10a-10b As shown, the pigmented self-cleaning substrate is non-iridescent. Such as Figures 10a-10b As shown, the colored self-cleaning substrate has a uniform self-cleaning layer. In other words, the aluminum alloy substrate achieves a non-iridesce...

Abstract

Provided are methods, apparatus and compositions for producing pigmented self-cleaning substrates by roll coating. Roll-coated pigmented self-cleaning substrates retain the predetermined color and predetermined gloss of the pigmented paint, thereby facilitating its use in architectural applications. Roll-coated pigmented self-cleaning substrates may be non-iridescent.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 230953, filed August 3, 2009, entitled "SELF- CLEANING SUBSTRATESAND METHODS FORMAKING THESAME," which is incorporated by reference in its entirety. Background technique [0003] Titanium dioxide (TiO 2 ) can promote photocatalysis under suitable environmental conditions. However, will contain TiO 2 The application of coatings to substrates such as those used in building products without detrimentally affecting the aesthetic characteristics of such substrates has proven difficult and cost ineffective. Contents of the invention [0004] The present disclosure relates to methods of producing pigmented, self-cleaning substrates by roll coating. Roller coating, also known as coil coating, is a high-speed method for applying coatings to substrates. These newly pigmented, self-cleaning substrates retain the target color and / or gloss of the origi...
