ABSTRACT:
A self-cleaning coating film is formed using a self-cleaning coating composition including an oxidation, catalyst mixed within a composition including silicone synthetic resin and an organic solvent. The oxidation catalyst includes at least one element selected from a metal such as a noble metal and a metal oxide such as manganese dioxide, copper oxide, iron oxide, nickel oxide, chrome oxide, and the like. The metal is blended with a powder made of alumina, or the like, in the range of about 0.1 to 1.0 weight %. The diameter of the particles of the powder is on the order of about 40 to 300.mu.. The powder is mixed with the composition in the range of about 5 to 100 weight %. The metal oxide is present in the composition at about 50 weight %. The self-cleaning coating film is formed at about 40 to 300.mu. thickness. The thus formed self-cleaning coating film is exposed to an elevated temperature of about 300.degree. to 400.degree. Centigrade for about 5 to 10 minutes, whereby the silicone synthetic resin is carbonized to form a film of SiO.sub.2.
