Features Of Domestic DMDC MACM Diamine Curing Agent

  1. High reactivity with epoxy resins, enabling rapid cure at ambient or moderate elevated temperatures.

  2. Excellent thermal stability and glass transition temperature (Tg) enhancement in cured systems.

  3. Low volatility and reduced amine odor compared to conventional aliphatic diamines.

  4. Superior chemical resistance—particularly to solvents, alkalis, and mild acids—after full cure.

  5. Consistent batch-to-batch quality and purity, meeting stringent domestic pharmaceutical-grade manufacturing controls.

Typical Applications Of Domestic DMDC MACM Diamine Curing Agent

  1. High-performance structural adhesives for aerospace composite bonding.

  2. Electrical encapsulants and potting compounds requiring low dielectric loss and high insulation resistance.

  3. Wind turbine blade matrix resins demanding extended pot life and reliable mechanical performance.

  4. Coating systems for offshore oil & gas infrastructure exposed to humid, saline environments.

  5. 3D printing (SLA/DLP) build platform adhesives requiring precise debonding control and residue-free release.
