Applications of LF-PV11 Phenyl Vinyl Silicone Fluid


  • LED Encapsulation Formulations

    Vinyl-functional ingredients for phenyl silicone formulation development. LF-PV11-53 can be evaluated where a higher-refractive-index vinyl ingredient is sought; LF-PV11-43 provides a higher-viscosity, lower-refractive-index option.

  • Electrical Insulation Formulations

    Vinyl-functional ingredients for compatible addition-cure silicone insulation systems.

  • Reactive Silicone Resin Modification

    Reactive ingredients for compatible Si-H-functional silicone resin systems.


Package & Storage of LF-PV11 Phenyl Vinyl Silicone Fluid


  • Packed in 25 kg and 200 kg drums.

  • Store in a cool, dry, well-ventilated place away from direct sunlight and fire sources. In unopened containers, shelf life is 12 months from the date of production. Storage beyond this period does not necessarily make the product unusable; verify the properties required for the intended use before use.
