SM-ER-39 Resin
Fluorine-containing bisphenol-A epoxy with good dielectric properties.
Product Description：
SM-ER-39 is a fluorine-containing bisphenol-A epoxy resin designed for advanced electronics. The introduction of fluorine atoms imparts exceptional heat resistance, excellent anti-corrosion properties, and remarkably low dielectric loss.
Classic Applications:
Low-dielectric composites for high-frequency telecommunications.
Excellent thermal stability and moisture resistance.
High wear and corrosion resistance.
Specialty electronic encapsulants and IC packaging
