jER™ YX8000D
jER™ YX8000D is a hydrogenated bisphenol A type liquid epoxy resin with significantly lower chlorine impurity levels than other commercially available products.
Its excellent transparency and better adhesiveness are suitable for wide variety of optical adhesives and encapsulants.
This grade has higher photocure reaction rate, contributing your photocuring process to be more efficient compared to conventional cycloaliphatic epoxy resins.
Application of YX8000D
- ・LED/OLED encapsulant, LED reflector
- ・Achieve high transparency formulation
- ・Achieve high transparency formulation
- ・Adhesives for optical devices (electro-optic assemblies, and laser components)
- ・Improving UV resistant
