ELECTRODEPOSITABLE CATHODIC RESIN COMPOSITION, RESET COMPOSITION METHOD BY CATHODIC ELECTRODEPOSITION, WATER BATH OF ELECTRODEPOSITABLE CATHODIC COATING AND ARTICLE COATED WITH ELECTRODEPOSPOSABLE COATING COMPOSITION

摘要

Oxime blocked polyisocyanate cross-linking agents for use with amine epoxy resin adducts in cathodic electrodeposition processes. The oxime blocking agents are the reaction products of acyclic aliphatic carbonyl-containing compounds having at least 7 carbon atoms and hydroxylamine. The oxime blocked polyisocyanates produce cathodic electrodeposited coatings which are smoother than coatings produced by oxime blocked polyisocyanates known in the art.
