ABSTRACT:
An aliphatic, isocyanate-base, polyurethane polymer and a process for preparing the polymer. The process comprises reacting, such as by spraying onto a substrate or an open mold, a caprolactone polyol with an aliphatic polyisocyanate in the presence of a catalytic amount of a metallo catalyst, and also in the presence of a fast-curing amount of a curing agent comprising an amine, particularly an aromatic diamine, such as diethyl toluene diamine, to provide a fast-reaction aliphatic polyurethane polymer.
