General description

4,4′-Methylenebis(2-methylcyclohexylamine) is an alicyclic diamine.

Application

4,4′-Methylenebis(2-methylcyclohexylamine) (MMCA) may be used:
  • in the synthesis of fully aliphatic polyimides
  • in the synthesis of fully aliphatic polyimide-siloxanes (APISiO)
  • to prepare epoxy resin with trimethylolpropane triglycidyl ether, used for the characterization of the structural organization in dragline silk by transmission X-ray microscopy (STXM).
