<p>A process for coating an object especially sanitary ware at least partially with metallic, e.g. copper or precious metals, where optionally at least one pretreatment step is applied to activate the metal surface, an organosilane is applied to the metal surface by the so-called sol-gel process, and the coating obtained is converted to a polysiloxane coating is new. Independent claims are included for: (1) an object, preferably sanitary ware, obtainable as above; (2) a composition for coating of objects comprising an organosilane mixture of at lest one especially modified fluorosilanes, preferably from 1H, 1H, 2H, 2H-perfluorooctyl-triethoxysilane or from 1H,1H,2H, 2H-perfluorodecyl-triethoxysilane, and a (poly)-alkoxysilane, preferably 1,2-bis-triethoxysilylethane.</p> |
