Classification: C09D

Abstract:
An anti-corrosive coating which comprises:a water-borne polymeric complex comprising a strand of a -conjugated polymer selected from the group consisting of polyaniline, polypyrrole, polythiophene, poly(phenylene sulfide), poly(p-phenylene), poly(phenylene vinylene), poly(furylene vinylene), poly(carbazole), poly(thienylene vinylene), polyacetylene, and poly(isothianaphthene); a polymer strand selected from the group consisting of poly(acrylic acid), poly(methacrylic acid), poly(vinylmethylether-co-maleic acid), poly(methylmethacrylate-co-acrylic acid), poly(ethylmethacrylate-co-acrylic acid) and poly(acrylamide-co-acrylic acid), the polymer strand being non-covalently bonded to the -conjugated polymer strand; and a a non-conductive polymer, the non-conductive polymer being complexed with the water-borne polymeric complex, the water-borne polymeric complex having hydrophilic/hydrophobic regions configured to allow the coating to be water soluble prior to application of the coating onto a surface and water insoluble after the coating has been applied to the surface.
