Coating compositions, hydrophilic films, and hydrophilic film-coated articles
Abstract
A coating composition which is comprised of an emulsion of a silicone resin, typically a water-insoluble, silanol group-bearing silicone resin dispersed in water, and contains photocatalyst particles, typically titanium oxide forms a hydrophilic film having a water-drop contact angle of no more than 60° when irradiated with UV-containing light. The composition eliminates the use of organic solvents and has excellent dispersion and storage stability. Films obtained by applying this coating composition to the surface of substrates have excellent weathering resistance and antifouling properties due to a self-cleaning effect arising from the photocatalytic action of the particles.
