Identification & Functionality

jER™ YX7105 Features & Benefits

Product Highlights
  • Liquid type (easy to handle)
  • Flexibility, stretchability
  • Tough, High resistant to mechanical pressure (thermal decomposition, bending/warpage)
  • Strong adhesion

Applications & Uses

Usage & Application
  • Coating
  • Adhesives
  • Additives (Stress relaxer, Impact modifier)
  • Base film and sheet for wearable devices,
  • Printed Electronics (Resist Ink, Build-up wire board, Flexible printed wire board, Metal core printed circuit board)
  • Semiconductor (liquid mold compound, underfill, sidefill, diebonding, ACF, NCF, ACP, NCP)

jERTM YX7105 is a liquid-type epoxy resin with flexible properties that increases the impact resistance of e.g. coatings, adhesives, composites and potting & encapsulation materials.
