ABSTRACT:
The surfaces of articles of manufacture fabricated from aluminum and other material which are not permanently water wettable are rendered permanently water wettable by coating the surface with a continuous film of the free acid form of an acidic film forming polymer which forms water soluble salts, said film containing a curing agent for the polymer; contacting the polymer film under aqueous conditions with colloidal alumina or a polyvalent metal salt; curing the polymer to water insolubility; and, when required to render the cured film water wettable, hydrolyzing the surface portion only of the cured polymer.
