Features Of HDX-65E Curing Agent

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

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

  3. Low viscosity (200–300 mPa·s at 25°C) ensures easy handling, precise metering, and superior wetting of fillers and substrates.

  4. Low volatility and non-crystallizing nature provide extended pot life and consistent processing stability.

  5. Produces tough, flexible cured films with high impact resistance and low exotherm in thick-section applications.

Typical Applications Of HDX-65E Curing Agent

  1. High-performance epoxy flooring and industrial coatings for warehouses and cleanrooms.

  2. Structural adhesives for automotive composites and metal-to-composite bonding.

  3. Electrical encapsulants and potting compounds requiring thermal cycling stability.

  4. Repair mortars and grouts for concrete rehabilitation in infrastructure projects.

  5. Wind turbine blade bonding and lightning protection system primers.
