MEJORAS EN UN METODO PARA DEPOSITAR POR ELECTRODEPOSICION CATODICA UNA COMPOSICION DE RESINA

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.
