Features Of KUKDO KD-407A 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 treated plastics without requiring primers.

  3. Low viscosity (12,000–15,000 cP at 25°C) enabling easy processing, impregnation, and air release.

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

  5. Good thermal stability with glass transition temperature (Tg) of approximately 125–135°C after full cure.

Typical Applications Of KUKDO KD-407A Epoxy Resin

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

  2. Structural adhesive formulations for aerospace composite bonding and automotive metal-to-composite joints.

  3. Prepreg matrix resin for carbon fiber and fiberglass laminates in wind turbine blades and sporting goods.

  4. Castable insulation systems for medium-voltage switchgear and busbar supports.

  5. Coating and potting compound base for LED modules and power electronics requiring thermal management.
