Synthesized Ketimine--A Replacement Curing Agent for MOCA.

Abstract

MOCA (4-4'-methylene-bis-(2 chloroaniline)), manufactured by E. I. du Pont de Nemours and Co., Inc., and used as the curing agent in the AML P-7 rain erosion coating, has been classified by the Occupational Safety and Health Administration (OSHA) as a carcinogen. A ketimine (blocked diamine), synthesized by reacting methylene dianiline with a short chain carbonyl compound, has been found to be an excellent replacement for the carcinogenic MOCA. The physical properties of the ketimine cured AML P-7 elastomeric rain erosion coating are superior to the cured elastomer using MOCA as the cross-linking agent. (Author)
