Abstract:
1. A method to control corrosion of a metal substrate, the method comprising: applying a radiation-curable formulation to the metal substrate to obtain a coated substrate; and curing the coating on the substrate; wherein the radiation-curable formulation comprises: a radiation-curable resin; and at least 2% by weight of an oligomeric siloxane component which comprises a —Si—O—B— bond, based on the total formulation; wherein the oligomeric siloxane component is obtained by controlled hydrolysis and condensation of a silane monomer in the presence of boric acid, the silane monomer comprises an epoxy-functional silane of formula (I): wherein R R, R′ and R″ are independently, a hydrogen (H) or a linear, branched or cyclic, unsubstituted or substituted alkyl group having 1 to 6 C atoms, A and A′ are independently, a divalent alkyl group having 1 to 10 C atoms, and m is 0 or 1, and wherein the radiation-curable resin comprises at least one selected from the group consisting of an epoxy acrylate, a polyester acrylate, a polyether acrylate, a polyacrylate acrylate, and a urethane acrylate.
