Patent ID: 8178630

Claim:
A preparation, comprising: at least one oligomeric siloxane component, and at least one polymer component, wherein the oligomeric siloxane component is obtained by controlled hydrolysis and condensation, in the presence of boric acid, of at least one epoxy-functional silane of the general formula I R 1 —SiR′ m (OR) 3-m (I) in which R 1 is a group and the groups R, R′ and R″ are the same or different and are each a hydrogen (H) or a linear, branched or cyclic, optionally substituted alkyl group having 1 to 6C atoms, groups A and A′ are the same or different and are each a divalent alkyl group having 1 to 10C atoms, and m is 0 or 1, and wherein the polymer component is a hydroxyl-containing polymer selected from the group consisting of polyesters and polycarbonate polyols.
