Features Of GESR902 Epoxy Resin

  1. High purity bisphenol-A based liquid epoxy resin with consistent molecular weight distribution.

  2. Excellent adhesion to metals, composites, and cured polymer substrates.

  3. Low viscosity (12,000–14,000 cP at 25°C) enabling easy processing and impregnation.

  4. Superior thermal stability with glass transition temperature (Tg) of cured system ≥125°C.

  5. Low chloride content (<500 ppm), ensuring high electrical insulation performance.

Typical Applications Of GESR902 Epoxy Resin

  1. Electrical encapsulation and potting compounds for power electronics and transformers.

  2. Structural adhesive formulations for aerospace composite bonding.

  3. High-performance laminating resins for printed circuit board (PCB) prepregs.

  4. Wind turbine blade matrix resin in carbon fiber reinforced systems.

  5. High-voltage insulators and bushing casting applications.
