Features Of KUKDO KD-438 Epoxy Resin

  1. High reactivity with standard amine and anhydride curing agents for rapid gelation and short cycle times.

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

  3. Low viscosity (11,000–13,000 cP at 25°C) enabling easy handling, impregnation, and air-release in casting and laminating processes.

  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 with DDS hardener.

Typical Applications Of KUKDO KD-438 Epoxy Resin

  1. Electrical encapsulation of transformers, reactors, and high-voltage insulators.

  2. Structural bonding in wind turbine blade assembly and aerospace composite components.

  3. Castings for precision tooling, jigs, and industrial molds requiring dimensional stability.

  4. Laminating resin for high-performance fiberglass and carbon fiber prepregs.

  5. Underfill and glob-top encapsulation in power electronics modules.
