Features Of KUKDO SM-660A Epoxy Resin

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

  2. Excellent adhesion to metals, composites, and treated plastics under demanding thermal and mechanical conditions.

  3. Low viscosity (12,000–15,000 cP at 25°C) enabling easy processing, impregnation, and air-release without solvent addition.

  4. Superior electrical insulation properties with high dielectric strength (>18 kV/mm) and volume resistivity (>1 × 10¹³ Ω·cm).

  5. Good chemical resistance to alkalis, diluted acids, and common solvents after full cure.

Typical Applications Of KUKDO SM-660A Epoxy Resin

  1. Electrical encapsulation and potting of transformers, inductors, and high-voltage sensors.

  2. Structural adhesive formulation for aerospace composite bonding and automotive powertrain components.

  3. Matrix resin for filament-wound pressure vessels and fiber-reinforced piping systems.

  4. Insulating varnish and coating for motor windings and generator stators.

  5. Base resin in high-performance composite tooling and mold-making applications.
