The invention relates to a process for producing functional coatings with organofunctional silanes, a metal compound and difficultly volatile oxides, in which n a) a hydrolytic condensation is performed, optionally in the presence of a condensation catalyst and/or additives, of the following components n 1. at least one crosslinkable organofunctional silane, n 2. at least one metal compound, n 3. optionally at least one non-crosslinkable organofunctional silane and n 4. optionally one or more difficultly volatile oxides soluble in the reaction medium; n b) that to said hydrolytic condensate is added an organic, crosslinkable prepolymer; and n c) the thus obtained coating solution is applied to a substrate and subsequently cured. |
