Abstract

The present invention relates to mixtures prepared from(A) at least one linear, branched, or cyclic monomeric organosilane having at least two silicon atoms with hydrolyzable and/or condensation-crosslinking groups in which the silicon atoms are bonded to one another through at least one carbon atom in a linking unit, and(B) at least one boron- and/or aluminum-containing compound having the formula (I)RxM(OR′)3−x  (I) whereinM is Al or B,x is 0, 1, or 2,R is C1-C6-alkyl, C6-C12-aryl, or (O)½, with the proviso that if R is (O)½, then the compound of the formula (I) is a chain when x is 1 and a cyclic or cage-form compound when x is 2, andeach R′ is independently H, C1-C10-alkyl, or C6-C12-aryl. The invention further relates to hybrid materials prepared from such mixtures and to coatings produced therefrom.
