Features Of DX-75A Curing Agent

  1. Fast-reacting aliphatic amine-based curing agent for room-temperature and elevated-temperature epoxy systems.

  2. Excellent chemical resistance to acids, alkalis, and solvents after full cure.

  3. Low viscosity (200–300 mPa·s at 25°C) enabling easy metering, mixing, and deep-section penetration.

  4. Low volatility and negligible odor — supports safer handling and improved workplace compliance.

  5. Provides high glass transition temperature (Tg > 100°C) and superior mechanical strength in cured epoxy networks.

Typical Applications Of DX-75A Curing Agent

  1. Structural adhesives for aerospace composite bonding and metal-to-composite joining.

  2. High-performance protective coatings for industrial flooring and chemical containment linings.

  3. Electrical encapsulants and potting compounds for power electronics and EV battery modules.

  4. Wind turbine blade adhesive systems requiring rapid fixture and long-term environmental stability.

  5. Tooling resins and casting compounds for precision molds and prototype manufacturing.
