ABSTRACT:
A sealant or coating composition admixture contains a blocked isocyanate-terminated prepolymer in which generally all of the NCO groups are blocked, a curing agent such as a polyamine or a polyimine, and a functional silane or siloxane nonreactive with blocked isocyanates. The sealants or coating compositions when cured have improved properties such as adhesion.
