Features Of Sanmu SM-019 Bisphenol A Epoxy Resin

  1. High epoxy equivalent weight (EEW) of 480–520 g/eq, ensuring excellent reactivity control and balanced crosslink density.

  2. Low viscosity at 25°C (12,000–15,000 cP), enabling easy handling, mixing, and processing in solvent-free or low-solvent systems.

  3. Superior thermal stability with glass transition temperature (Tg) of cured resin exceeding 125°C after post-cure.

  4. Consistent batch-to-batch reproducibility, meeting ISO 9001-certified manufacturing standards.

  5. Low chloride content (< 750 ppm), minimizing corrosion risk in metal-coating and electronic encapsulation applications.

Typical Applications Of Sanmu SM-019 Bisphenol A Epoxy Resin

  1. Electrical insulation coatings for transformers, reactors, and busbars.

  2. Structural adhesives in aerospace and automotive composite bonding.

  3. Prepreg matrices for high-performance carbon fiber laminates.

  4. Encapsulation resins for power electronics and LED modules.

  5. High-durability flooring and protective linings for chemical storage tanks.
