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.

Abstract: A reactive diluent for use in an amine-containing epoxy resin composition. The reactive diluent comprises a soft, blocked isocyanate crosslinking agent. This reactive diluent is incorporated into the resin in addition to the primary crosslinking agent. The use of the reactive diluent eliminates or substantially reduces the need for volatile organic coalescent solvents and produces smooth, durable corrosion resistant coatings.
