Features Of HDX-75M Curing Agent

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

  2. Low viscosity (200–300 mPa·s at 25°C) ensures excellent mixability and air-release in formulated resins.

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

  4. Low volatility and reduced amine odor compared to conventional DETA-type hardeners, enhancing workplace safety.

  5. Enables high glass transition temperature (Tg > 85°C) and excellent mechanical strength in cured epoxy networks.

Typical Applications Of HDX-75M Curing Agent

  1. Structural adhesives for aerospace and automotive bonding applications.

  2. High-performance protective coatings for concrete flooring and industrial steel substrates.

  3. Electrical encapsulants and potting compounds requiring thermal stability and dielectric integrity.

  4. Composite matrix resins in wind turbine blade and marine component manufacturing.

  5. Repair mortars and grouts where rapid strength development and low shrinkage are critical.
