}}4,4-Diaminodicyclohexylmethane is the name for organic compounds with the formula CH2(C6H10NH2)2. It is classified as a diamine. In the epoxy industry it is often referred to as PACM or Para Amino diCyclohexyl Methane hence the PACM name. It is used as a curing agent for epoxy resins[1] and to produce diisocyanates, which are precursors to polyurethane. The mixture is a colorless solid, but typical samples are yellowish and oily. The compound is produced as a mixture of three isomers by the hydrogenation of methylenedianiline.[2] These isomers are, in decreasing order of their yield from the hydrogenation, trans-trans, cis-trans, and a small amount of cis-cis.[3]

Safety

It is an alkaline skin irritant. At 300 – 1000 mg/kg (oral, rats), the {{LD50}} is low. It does not exhibit mutagenic properties.
