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