jER™ YX7105
jER™ YX7105 is a liquid-type epoxy resin with toughness, flexibility, and high stretchability.
It is used as an impact modifier for printed electronics and wearable devices to avoid bending and warpage.
YX7105 also has strong resistant to thermal decomposition and strong adhesion property, so it is an ideal material for adhesives and coating in semiconductor and printed electronics application.
Application of YX7105
・Coating and Paints
- ・Giving toughness and impact strength
