Abstract:
A method for corrosion-proofing a metal substrate, comprising:applying a bond coating to the substrate, the bond coating consisting essentially of at least one organic adhesion-conferring polymer, said organic adhesion-conferring polymer consisting essentially of at least one polybismaleimide selected from the group consisting of: (i) a homopolymer comprising a bismaleimide, (ii) a homopolymer comprising a maleimide-terminated oligomer, (iii) a homopolymer comprising a maleimide-terminated polymer, (iv) a copolymer comprising a bismaleimide, (v) a copolymer comprising a maleimide-terminated oligomer, and (vi) a copolymer comprising a maleimide-terminated polymer wherein the coating is applied from an aqueous solution, an organic solvent solution, a dispersion or an emulsion; and subsequently stabilizing the bond coating on the substrate surface.
