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
