Phenyl methyl hydrogen silicone resin IOTA207 Taking hydrogen ring body D4H, imported D4, phenyl monomer as raw materials, with a special post-treatment process synthetic hydrogen methyl phenyl silicone resin, it has excellent Si-H activity and is crosslinker of the manufacture of high temperature liquid molding silicone rubber, reliable high refractive phenyl LED package silicone. Technical Specifications: 1. Appearance: colorless transparent liquid. 2. Viscosity :( 25 ℃ mm2 / s) 200 ~ 3000 3. Refractive index (25 ℃): 1.49 ~ 1.53 The hydrogen content (%, m / m) ≥: 0.3-0.5 5. Volatile (150 ℃, 4h): <1% Performance: 1. Because Phenyl methyl hydrogen silicone resin contains the active Si-H bonds, it can participate in a variety of chemical reactions, has good film-forming properties; 2. In the presence of a base or Lewis acids etc. under, it can react with R-OH or HO role and release H2; 3, It is can easily react with vinyl compounds in the presence of platinum complex; 4, in the addition reaction, the reaction temperature is low, the catalyst was less, the reaction was complete, colorless and tasteless.
