Bisphenol A Epoxy Resins

Liquid Epoxy Resin

Product Features

The liquid bisphenol A epoxy resin product series is a class of liquid resins produced by the polymerization of bisphenol A and epichlorohydrin. This resin family offers stable specifications and consistent performance for a range of downstream applications. Hebang mainly classifies these products by epoxy equivalent, viscosity, and hydrolyzable chlorine content, while focusing on color, processing flowability, bubble release, and dielectric performance so relevant indicators can be controlled and adjusted for different downstream applications.
