jER™ YX7105
- Chemical Family
- Epoxy & Epoxy Derivatives
jER™ YX7105 is a liquid-type epoxy resin with toughness, flexibility, and high stretchability. It is used as an impact modifier for semiconductor, printed electronics and wearable devices to avoid bending and warpage. jER™ YX7105 is an adduct formed from the reaction of epichlorohydrin and an aliphatic and aromatic polyol.FeaturesExcellent adhesionGood toughnessGood mechanical, impact and crack resistanceExcellent elasticity and flexibilityApplicationsPrinted electronics (resist ink, build-up wire board, flexible printed wire board, metal core printed circuit board)Semiconductor manufacturing (liquid mold compound, underfill, sidefill, diebonding, ACF, NCF, ACP, NCP)Base film and sheet for wearable devicesCoatingsAdhesives *jER™ is provided by Mitsubishi Chemical Corporation, a member of the Mitsubishi Chemical Group.
