ABSTRACT:
Amine curable polymers or prepolymers such as urethanes are cured by the use of a methylene dianiline complex or a racemic 2,3-di(4-aminophenyl) butane complex in the presence of a high dielectric constant catalytic compound which is relatively non-reactive with amines and isocyanates and exclusive of halogen containing foaming agents, halogen containing acids, and halogen containing flame retardants, so that increased cure rates, decreased cure temperatures or both are readily obtained.
