Feature of Silanol Terminated Vinyl Silicone Oil LC-208

  • Advantages of dual functional group modification: The synergistic reaction between hydroxyl and vinyl groups can participate in various cross linking systems such as addition and condensation, and is suitable for different curing processes (such as platinum catalyzed addition and organotin catalyzed condensation). The flexibility of modification far exceeds that of single functional group silicone oil

  • Strong processing adaptability: low viscosity specifications with excellent fluidity, easy to mix and disperse with fillers and cross linking agents; Medium to high viscosity specifications can enhance the mechanical strength of the substrate, while balancing processing convenience and finished product performance

  • Performance design ability: By adjusting the vinyl content and molecular weight, the hardness, elasticity, and tear strength of the finished product can be customized to meet the performance requirements of different scenarios

  • Weather resistance and stability: Retain the aging and chemical resistance properties of silicone oil, and the cross-linked product will not yellow or become brittle after long-term use, meeting high-end industrial application standards.


Applications of Silanol Terminated Vinyl Silicone Oil LC-208

  • Used as constitution controller of silicone rubber and anti-sticking of make paper.

  • Added vinyl chain link (side chain position) in the hydroxy silicone molecule. Adding this product can play a dual role: the hydroxy group in the molecule and the active group of silica should act as a structure control agent.

  • It can be used alone or in combination with hydroxy silicone oil.
