Features Of ADEKA EP-4080E Bisphenol A Epoxy Resin

  1. High epoxy equivalent weight (EEW) for controlled crosslink density and reduced exotherm in thick-section casting.

  2. Excellent hydrolytic stability, enhancing long-term performance in humid or outdoor environments.

  3. Low ionic chloride content (< 500 ppm), minimizing corrosion risk in metal-reinforced composites and electronic encapsulants.

  4. Optimized viscosity (12,000–16,000 mPa·s at 25°C) for improved filler loading and processability in high-solids formulations.

  5. Consistent batch-to-batch reproducibility, meeting stringent quality requirements for aerospace and industrial coatings.

Typical Applications Of ADEKA EP-4080E Bisphenol A Epoxy Resin

  1. High-performance electrical potting and encapsulation compounds for power electronics and EV components.

  2. Structural adhesives requiring thermal stability and low shrinkage during cure.

  3. Heavy-duty protective coatings for offshore platforms and chemical processing equipment.

  4. Reinforced polymer composites in wind turbine blade root joints and mining equipment parts.

  5. High-gloss, UV-resistant industrial floor coatings with enhanced abrasion resistance.
