Features Of Modified Cycloaliphatic Amine Curing Agent WK-6610

  1. Enhanced thermal stability for high-performance epoxy systems operating up to 180 °C.

  2. Low viscosity (250–400 mPa·s at 25 °C) enabling excellent processability and filler wetting.

  3. Reduced exotherm peak temperature during cure, improving safety in thick-section casting.

  4. Good compatibility with standard bisphenol-A and novolac epoxy resins.

  5. Improved humidity resistance compared to conventional aliphatic amines, supporting outdoor applications.

Typical Applications Of Modified Cycloaliphatic Amine Curing Agent WK-6610

  1. High-voltage electrical encapsulants and potting compounds.

  2. Structural adhesives for aerospace and automotive composites.

  3. Thick-section castings for industrial tooling and dielectric components.

  4. UV-resistant protective coatings for wind turbine blades and marine structures.

  5. Electronics underfill and conformal coating formulations requiring low stress and high Tg.
