Features Of GEKR379 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 under ambient and elevated temperature conditions.

  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 (>18 kV/mm) and volume resistivity (>1 × 10¹³ Ω·cm).

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

Typical Applications Of GEKR379 Epoxy Resin

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

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

  3. Matrix resin for filament-wound pressure vessels and carbon fiber reinforced components.

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

  5. Underfill and glob-top materials in power electronics packaging requiring thermal and mechanical reliability.
