ABSTRACT:
A pressure sensitive structural adhesive or sealant composition comprises a) a polymer system containing from 95 to 15 percent by weight of a telechelic polymer such as a polyhydroxylated diene block polymer and from 5 to 85 percent by weight of a heterotelechelic polymer such as an epoxidized monohydroxylated diene block polymer, and b) a dual curing system wherein one element such as a polyisocyanate cures the telechelic polymer at ambient temperature, and the other element such as an amino resin cures the heterotelechelic polymer.
