Applications of LF-PH11 Phenyl Hydrogen Silicone Oil


  • LED Encapsulation Formulations

    Si-H-functional ingredients for phenyl silicone formulation development. LF-PH11-50 can be evaluated where a higher-refractive-index Si-H ingredient is sought; LF-PH11-43 provides a lower-refractive-index option.

  • Electrical Insulation Formulations

    Si-H-functional ingredients for compatible vinyl-functional silicone insulation systems.

  • Reactive Silicone Resin Modification

    Reactive ingredients for compatible vinyl-functional silicone resin systems.


Package & Storage of LF-PH11 Phenyl Hydrogen Silicone Oil


  • 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.
