ABSTRACT:
A low temperature cure electrodepositable cathodic resin is disclosed. The resin is the reaction product of a polyepoxide amine adduct and a novel blocked crosslinking agent. The crosslinking agent of our invention is tetramethylxylene diisocyanate blocked with any suitable blocking agent. The resulting resin can be cured at relatively low temperatures (250.degree.-275.degree. F.), which potentially allows the use of the resin with articles containing plastics.
