ABSTRACT:
A process of retaining or enhancing corrosion resistance of autodeposited coatings on metallic surfaces by contacting the uncured coating on the metallic surface with a rinse solution containing hydrofluorozirconic acid or a salt thereof, such as nickel or cobalt salt. The metallic surface may be cold rolled steel or galvanized steel. The resinous autodeposited coatings are poly{vinylidene chloride} polymers. Copolymers containing at least 50% by weight poly{vinylidene chloride} are suitable. Because the protective properties of the autodeposited coatings are improved on both types of steel, both may be processed simultaneously, providing practical and economic advantages.
