Features Of NPC NPES-904 Solid Epoxy Resin

  1. High epoxy equivalent weight (EEW) for controlled crosslink density and reduced exotherm during curing.

  2. Excellent thermal stability and long-term dimensional stability in cured matrix systems.

  3. Low volatile organic compound (VOC) content, supporting eco-friendly formulation requirements.

  4. Superior compatibility with standard amine and anhydride hardeners for versatile processing.

  5. Consistent batch-to-batch performance due to stringent polymerization control and purification.

Typical Applications Of NPC NPES-904 Solid Epoxy Resin

  1. Electrical insulation materials for high-voltage switchgear and transformer components.

  2. Structural adhesives requiring elevated heat resistance and low shrinkage.

  3. Prepregs and filament-wound composites in aerospace and wind energy applications.

  4. Encapsulants and potting compounds for power electronics and LED modules.

  5. High-performance coatings for corrosion protection in industrial and marine environments.
