IOTA 6208 is a methyl phenyl vinyl silicone resin synthesized from phenyl monomers through a special post-treatment process. With excellent Si-Vi reactivity, it is a reliable resin for manufacturing high-temperature liquid addition-cure silicone rubber and high-refractive-index phenyl LED encapsulation silicones.
✅ High reactivity – contains active Si-Vi bonds, participates in various chemical reactions with excellent film-forming properties
✅ Platinum-catalyzed addition – readily reacts with hydrogen-containing compounds in the presence of platinum complexes
✅ Mild reaction conditions – low addition reaction temperature, low catalyst dosage, complete reaction, colorless and odorless
✅ High refractive index – up to 1.54, suitable for high-refractive-index LED encapsulation systems
✅ High-temperature resistance – suitable for high-temperature liquid addition-cure silicone rubber
