ABSTRACT:
An improved aqueous cathodic electrocoating composition having a binder of an epoxy-amine adduct and a polyisocyanate crosslinking agent; wherein the improvement is the use of a polyisocyanate crosslinking agent having at least one crosslinkable morpholine dione group per molecule. Electrodeposited finishes are formed that have reduced volatile emissions and film weight loss when heated to cure.
