FORMULATIONS
MOCA-HR is usually used to cure prepolymers that are produced from TDI reacted with polyether or polyester polyol. The prepolymer normally contains NCO of 4.2 - 4.3 %. Pot life is usually 8 - 10 minutes.
MOCA-HR will show a significant reduction in properties if heated for long periods of time at temperatures in excess of 121.
TOXICITY
LD50 (Rats) 5000mg/kg.
OSHA PEL 0.02ppm (8-hour TWA), ACGIH TLV 0.01ppm.
MOCA has been classified as a carcinogen since 1973, based upon test results with laboratory animals. In 1992, ACGIH, after reviewing existing information, continued the classification of MBOCA as a "Suspect Human Carcinogen".
STORAGE
MOCA-HR should be stored in a dry location.
PACKAGING
Net 50-kg carton drum with polyethylene liner.
