DMDC (also known as MACM) is a bifunctional amine compound with an alicyclic structure. Its molecule contains two active amino groups and a cyclohexane backbone, frequently used as a reactive amine raw material in epoxy resin and polyurethane-related systems. Compared to aromatic amine materials, the alicyclic structure helps improve the material's performance in weather resistance and appearance stability.
Due to its molecular structure featuring moderate rigidity and steric hindrance design, DMDC provides excellent cross-linked structures within reaction systems. It balances processing operability with the overall performance of the cured material, making it suitable for industrial-grade formulations that require stable reaction behavior and long-term service reliability.
