Sanmu Epoxy Resin

The Sanmu epoxy resin series characterized by exceptional reactivity (epoxy value: 0.48–0.54 eq/mg), these resins enable robust cross-linking with diverse curing agents, forming thermally stable networks ideal for high-stress environments. Their low viscosity profile (20–45 Pa·s at 25°C) ensures effortless processing and deep substrate penetration, while high purity minimizes side reactions for consistent curing outcomes.

Optically transparent formulations and light coloration make the series suitable for aesthetic-sensitive applications, including protective coatings and adhesives requiring clarity or color retention. Enhanced electrical insulation properties, driven by ultra-low chlorine content, meet stringent requirements for electronic encapsulation, transformer components, and high-voltage insulation systems.
