Features of Cycloaliphatic Epoxy in LED Packaging Materials
Thermosetting epoxy resin, featuring good mechanical properties, low curing volume shrinkage, excellent adhesion force to substrates, and strong controllability of its operating processes, is one of the major packaging options for LEDs at present.Among them,cycloaliphatic epoxy resins, especially 3,4-epoxycyclohexyl-3,4-epoxycyclohexyl ester (TTA21), are preferably and widely applied in LED and optical device encapsulants for their excellent processability, high Tg point and good weather resistance.
