HMDA (also known as PACM) is a bifunctional primary amine compound with an alicyclic structure. Its molecule contains two active amino groups linked by a cyclohexane backbone, frequently used as a reactive amine raw material in epoxy resins, polyurethanes, and related polymer systems. Its alicyclic structure helps improve the material's performance in weather resistance and appearance stability.
Due to its molecular structure possessing both a degree of rigidity and excellent reaction controllability, HMDA can form stable cross-linked structures within resin reaction systems. It assists formulations in achieving a balance between processability, structural stability, and long-term service reliability, making it suitable for industrial applications with high requirements for material quality and durability.
