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. Package: 1. 5kg Polyethylene plastic barrel 2 the product should be stored in clean, closed containers, avoid contact with acid, alkali and mixed with other impurities, do not touch the fire. 3. the product should be stored in a cool dry place, avoid direct sunlight, the storage period of six months, can still be used after passing inspection expired.
