<p>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) R x M(OR') 3-x (I) wherein M is Al or B x is 0, 1, or 2, R is C1-C6-alkyl, C6-C12-aryl, or (O)1/2, with the proviso that if R is (O)1/2, 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, and each 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.</p> |
