一、Application description
LED has HT-601A/B-1 epoxy resin, HT-601A-1 of host and HT-601B-1 of curing agent. The epoxy resin has low viscosity under common temperature and can be used for long-term, mesotherm, fast-speed to solidity in high temperature, good mechanical strength of condensate, behavior of electricity, thermal endurance, transparency, small percentage of contraction, excellent TG value, thermostability that is applied for sealing LED
