jER™ YX7105
jER™ YX7105 is a flexible thermosetting epoxy resin with excellent heat, chemical, and water resistance. It is recommended for use in printed electronics, semiconductor manufacturing, coatings, adhesives, and base films and sheets for wearable devices.
jER™ YX7105 is a liquid-type epoxy resin formed from reacting epichlorohydrin and an aliphatic and aromatic polyol. It has excellent adhesiveness, flexibility, impact resistance, and stretchability. It is compatible with a variety of substrates, including glass, fibers, fabrics, metals, plastics, steel, aluminum, ceramic, concrete, and masonry. It contributes excellent insulation, heat, chemical, water, and impact resistance to these materials when used in semiconductors, printed electronics, and wearable devices to avoid bending and warpage.
