Abstract:
Liquid compositions are disclosed that include a photocatalytic material and a hydrophilic binder that includes an essentially completely hydrolyzed organosilicate. Also disclosed are methods of making such compositions, methods of coating a substrate with a hydrophilic composition, and substrates coated with such compositions. The compositions may, for example, be embodied as stable one-pack compositions.
Abstract:
A method for modifying the appearance of a substrate is disclosed. The method includes providing a substrate having first and second opposing surfaces and depositing a reflectance modifying coating on at least a portion of the first surface of the substrate, wherein the second surface has a visible light reflectance (R1) ranging from 5 to 20 percent.
Abstract:
Multi-layer coatings are disclosed that include (a) a first layer deposited from at least one composition that includes a polymeric composition, and (b) a second layer applied over at least a portion of the first layer in which the second layer is deposited from at least one liquid composition that includes (i) a photocatalytic material, and (ii) a binder that is hydrophilic and comprises an essentially completely hydrolyzed organosilicate. Also disclosed are substrates coated with such multi-layer coatings, methods of applying such multi-layer coatings to a substrate and methods of making a painted surface easy-to-clean.
Abstract:
A method is provided for simulating and/or demonstrating and/or enhancing photoactive properties, such as hydrophilicity, of a surface, such as a photoactive surface. One embodiment includes providing a photoactive surface and applying a peroxide-containing material, such as an aqueous hydrogen peroxide solution, over at least a portion of the surface. An optional resinous layer, such as an at least partly hydrolyzed polymethoxysiloxane layer, can be applied over the surface. A kit to practice the method and an article made using the method are also provided.
