摘要： An improved process for applying a lead-free coating by electrodeposition to an untreated ferrous metal substrate is provided. The substrate need not be phosphated prior to treatment. The process includes the following steps: a) contacting the substrate surface with a group IIIB or IVB metal compound in a medium that is essentially free of accelerators needed to form phosphate conversion coatings; followed by b) electrocoating the substrate with a substantially lead-free, curable electrodepositable composition; and c) curing the electrodepositable composition. The group IIIB or IVB metal compound is preferably a zirconium compound and is typically in an aqueous medium. The process may further include initial steps of cleaning the substrate with an alkaline cleaner and rinsing with an acidic rinse. Substrates treated by the process of the present invention demonstrate excellent corrosion resistance.

摘要： A cationic resin containing blocked isocyanate groups which is suitable for use in electrodeposition is disclosed. The cationic resin is derived from an epoxy resin and contains in the resin molecule cationic salt groups, active hydrogen groups and blocked isocyanate groups. The blocked isocyanate groups are incorporated into the resin molecule by reacting the epoxy resin with a compound selected from the class consisting of mercapto compounds and acid group-containing compounds where the compounds also contain blocked isocyanate groups. The resin can be formulated into an electrocoating composition which is free of lead and yet provides outstanding corrosion resistance when electrodeposited over steel substrates. The outstanding corrosion resistance can be attained when the substrate has not been given a chrome rinse which is conventional in pretreating the steel substrate before electrodeposition.
