jER™ Epoxy YX7110

jER™ YX7110 is a tough and flexible liquid-type epoxy resin. It can be used as an impact modifier for brittle materials, as an additive to increase impact resistance, and for stress relaxation to avoid cracking and warpage. jER™ YX7110 is an adduct formed from the reaction of epichlorohydrin and an aliphatic and aromatic polyol. Features Adduct formed from the reaction of epichlorohydrin and an aliphatic and aromatic polyol Crack and impact resistance Excellent flexibility and elasticity High viscosity Low warpage Maintains flexibility even after full-curing Applications Coatings Adhesives Composites Potting and encapsulation materials Base film/sheet for wearable devices *jER™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.
