Features Of NPC 128 Epoxy Resin

  1. Highly reactive bisphenol-A based liquid epoxy resin with low viscosity for excellent processability.

  2. Superior adhesion to metals, composites, and cured thermosets without mandatory surface priming.

  3. Excellent chemical resistance to dilute acids, alkalis, and polar solvents after full cure.

  4. Low volatile organic compound (VOC) content, compliant with industrial environmental safety standards.

  5. Consistent batch-to-batch performance ensured by strict in-process quality control and ISO-certified manufacturing.

Typical Applications Of NPC 128 Epoxy Resin

  1. Structural adhesive formulations for aerospace composite bonding and metal-to-composite joints.

  2. Matrix resin in filament-wound pressure vessels and high-pressure composite tanks.

  3. Electrical encapsulation and potting of high-voltage transformers and power electronics modules.

  4. Coating binder for corrosion-resistant linings in chemical storage tanks and piping systems.

  5. Base resin in advanced carbon fiber prepregs for automotive lightweight structural components.
