Features Of KUKDO SM604RF Epoxy Resin

  1. High reactivity with amine and anhydride hardeners for rapid cure at ambient or elevated temperatures.

  2. Excellent adhesion to metals, composites, and cured epoxy substrates without surface priming.

  3. Low viscosity (12,000–15,000 cP at 25°C) enabling easy processing, impregnation, and void-free casting.

  4. Superior electrical insulation properties with high dielectric strength and volume resistivity.

  5. Good thermal stability with glass transition temperature (Tg) up to 125°C after full cure.

Typical Applications Of KUKDO SM604RF Epoxy Resin

  1. Electrical encapsulation of power modules, IGBTs, and high-voltage sensors.

  2. Structural adhesive formulations for aerospace composite bonding and repair.

  3. Underfill and glob-top protection for fine-pitch semiconductor packaging.

  4. High-performance potting compounds for outdoor LED drivers and renewable energy inverters.

  5. Matrix resin for carbon fiber reinforced laminates requiring low exotherm and dimensional stability.
