Abstract

The invention relates to a process for producing functional coatings with organofunctional silanes, a metal compound and difficultly volatile oxides, in whicha) a hydrolytic condensation is performed, optionally in the presence of a condensation catalyst and/or additives, of the following components1. at least one crosslinkable organofunctional silane,2. at least one metal compound,3. optionally at least one non-crosslinkable organofunctional silane and4. optionally one or more difficultly volatile oxides soluble in the reaction medium;b) that to said hydrolytic condensate is added an organic, crosslinkable prepolymer; andc) the thus obtained coating solution is applied to a substrate and subsequently cured.
