Methyl Phenyl Silicone Resin : Guide
Methyl phenyl silicone resin is commonly used as the base resin for high-temperature resistant coatings, specialized coatings, and general high and low-temperature resistant insulating varnishes. It is also ideal for masking varnishes (including varnishes, paints, magnetic varnishes), moisture-proof capacitor impregnation, H-class electrical insulating materials, and special paper treatments.
This resin, a phenyl methyl hydrogen silicone resin, is synthesized using hydrogen cyclic D4H, imported D4, and phenyl monomers as raw materials. Through a specialized post-processing method, hydroxymethyl phenyl silicone resin is produced, which boasts excellent Si-H activity. It serves as a reliable crosslinking agent for high-temperature liquid molded silicone rubber and is also used in the production of high-refractive index phenyl LED encapsulation silicone gels.
