Features Of GESR901H Epoxy Resin

  1. High reactivity with amine and anhydride hardeners for rapid gelation and reduced cycle times.

  2. Excellent adhesion to metals, composites, and treated plastics under ambient and elevated cure conditions.

  3. Low viscosity (8,000–12,000 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 chemical resistance to weak acids, alkalis, and solvents after full cure.

Typical Applications Of GESR901H Epoxy Resin

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

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

  3. Matrix resin for filament-wound pressure vessels and fiber-reinforced polymer (FRP) tanks.

  4. Underfill and glob-top protection for power electronics and IGBT modules.

  5. Castings and potting compounds for industrial sensors and control system housings.
