ABSTRACT:
A polyurethane sealant composition is made from a polyurethane prepolymer having blocked isocyanate groups. A bicyclic amidine catalyst is utilized in association with an amine curing agent having at least two primary amine groups to achieve a relatively fast cure time. In the first embodiment, the catalyst is 1,8-diazobicyclo (5:4:0) undecene-7 (DBU), whereas in a second embodiment the catalyst is 1,5-diazobicyclo (4:3:0) non-5-ene (DBN).
