WL-700A/B is heat-cured encapsulating epoxy resin. They consist of main agent, curing agent and DF-090 light diffusing agent. The main compositions are electronic class low viscosity epoxy resin, additive, acid anhydride, and light diffusing filler. Following are their main features:
1. Low mixing viscosity, good degassing characteristics.
2. long pot life at room temperature, rapidly curing at medium temperature.
3. Outstanding mechanical, physical properties and low shrinkage rate after curing.
4. Good transparency after curing.
