Features Of KUKDO KD-420 Epoxy Resin

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

  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 via casting, impregnation, and filament winding.

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

  5. Good chemical resistance to dilute acids, alkalis, and aliphatic solvents after full cure.

Typical Applications Of KUKDO KD-420 Epoxy Resin

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

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

  3. Matrix resin for glass-fiber and carbon-fiber reinforced laminates in aerospace tooling.

  4. High-performance potting and casting of industrial sensors and power electronics modules.

  5. Insulating coatings for busbars, generator stators, and medium-voltage switchgear.
