ABSTRACT:
A plastisol composition comprising polyvinyl chloride as a main component, a plasticizer and a blocked compound of diisocyanate polymer with styrenated phenol as an adhesion-improver, and optionally a powdery curing agent having a melting point of 50.degree. to 150.degree. C. which is surface-treated, said composition having improved adhesion properties when gelated under low temperature conditions such as at 110.degree. to 130.degree. C. for 15 to 30 minutes and being useful as an adhesive, a sealant, or a coating agent, particularly as a sealant for the body of automobiles, and a novel blocked polyisocyanurate compound useful as an adhesion-improver for the above plastisol composition and also as an adhesive, a coating agent, a sealant, and an crosslinking agent for an active hydrogen-containing high molecular weight compound.
