Abstract:
In an improved method for electrolytically debonding a paint coating from a metal member wherein the paint coating is bonded to a surface of the metal member, the improvement comprising:(a) providing an electrode blanket on said paint coating, said electrode blanket comprised of:(i) a first blanket in contact with said paint coating;(ii) a second blanket covering said first blanket; and(iii) an electrode mesh positioned between said first blanket and said second blanket;(b) applying an aqueous based electrolyte solution to said electrode blanket, said second blanket maintaining a substantially uniform presence of electrolyte in said first blanket; and(c) passing an electric current through said electrode blanket to said metal member, making said electrode blanket anodic and said metal member cathodic, and passing said current for a time sufficient to cause said paint coating to debond from the surface of said metal member without substantially chemically altering said paint coating.
