CATHODIC ELECTROCOATING COMPOSITIONS CONTAINING HYDROXYL-CARBONATE BLOCKED POLYISOCYANATE CROSSLINKING AGENT
摘要:
An improved aqueous cathodic electrocoating composition having a binder of an epoxy-amine adduct and a blocked polyisocyanate crosslinking agent; wherein the improvement is the use of a hydoxyl-carbonate blocked polyisocyanate crosslinking agent. Electrodeposited finishes are formed that have reduced weight loss when heated to cure.
