Overview
jER™ YX7110 is a liquid-type epoxy resin formed from reacting epichlorohydrin and an aliphatic and aromatic polyol that can be used as an impact modifier for brittle materials and stress relaxation to avoid cracking and warpage. It contributes flexibility, insulation, heat resistance, chemical resistance, and excellent wear and abrasion resistance when used in a variety of applications, including coatings, adhesives, composites, potting and encapsulation materials, base films/sheets for wearable devices, impact modifiers, and stress-relaxer additives.
