The researchers used alicyclic epoxy resins to react with diphenyldihydroxy and triphenylhydroxy groups to produce high refractive index (1.58), thermally stable, and UV-resistant silicone epoxy modified materials. Huang Yunxin and others first synthesized oligomeric silsesquioxanes with different molecular weights, and modified the bisphenol A epoxy resin with synthetic polyorganosiloxanes. The results showed that all three polysiloxanes can improve the epoxy resin. Product toughness and flexural strength. Yang Xin et al. Prepared a polyfunctional silicone epoxy resin through the hydrolysis and condensation reaction of 2- (3,4-epoxycyclohexyl) ethylmethyldiethoxysilane, using methylhexahydrophthalic anhydride as a curing agent The obtained product has greatly improved light transmittance and heat aging resistance, and is expected to be popularized and applied in the field of LED packaging materials. Crivello. J et al. Used double bond-containing epoxy monomers such as allyl glycidyl ether and 4-vinyl epoxycyclohexane to perform hydrosilylation reaction with hydrogen-containing polysiloxane to synthesize silicone Epoxy resin with good transparency and heat resistance.

Silicone epoxy resin has been widely used recently because it can embody the advantages of epoxy resin and silicone resin. It has demonstrated mechanical properties, adhesion, aging resistance, ultraviolet resistance, and refractive index. With excellent performance, it is the research direction of LED packaging materials in the future, and significant progress will be made.
