    • A crosslinker (i.e., a curing agent) for polymerizing a film-forming material. The crosslinker is an organic compound including at least two functional groups reactive with a film-forming material and at least one pendent group comprising a —Si(OR)3 group, wherein each R is independently an alkyl group including from 1 to about 12 carbon atoms or an aryl group including substituted and unsubstituted phenyl and benzyl groups. Functional groups reactive with a film-forming materials include isocyanate, blocked isocyanate, uretdione, epoxide, hydroxyl, carboxyl, ester, ether, carbamate, aminoalkanol, aminoalkylether, amide, or amine groups. Embodiments include derivatives of the various crosslinkers as disclosed elsewhere herein, where the crosslinker has at least two functional groups reactive with a film-forming material and at least one pendent group comprising a —Si(OR)3 group.
