ABSTRACT:
Alcohol catalysts are utilized to effect ambient temperature cure of urethane prepolymers or polymers with a methylenedianiline (MDA) salt complex. The alcohol catalysts are generally quasi polar such as a polyester polyol, a polyether polyol, an aliphatic polyol, or an aliphatic or an aryloxypoly(oxyalkylene) alcohol.
