4,4-Methylenebiscyclohexylamine
4,4′-Methylenebis(cyclohexylamine),also known as PACM (para-diaminodicyclohexylmethane), is an organic amine compoundcharacterized by the presence of two amine groups attached to adicyclohexylmethane backbone. It is primarily used as a hardener in epoxy resinformulations, where it plays a crucial role in cross-linking reactions,enhancing the mechanical properties and thermal resistance of the resultingmaterials. It has potential applications in the biomedical field, particularlyin the development of polymeric biomaterials. Its properties as a hardener inepoxy resin formulations allow for the creation of biocompatible materials thatcan be used in medical devices, implants, and tissue engineering scaffolds.
