    Product Description

    Vinyl Silicone Oil CAS 68083-19-2 is a vinyl-functional polydimethylsiloxane fluid with EINECS 614-275-5.

    Synonyms: Vinyl-terminated polydimethylsiloxane; Vinyl terminated PDMS; Vinyl silicone oil.

    CAS: 68083-19-2.

    It is supplied as a colorless to transparent liquid in different viscosity grades.

    It is also known as vinyl-terminated PDMS or ViPDMS.

    It is mainly used as a base polymer or reactive component in addition-cure silicone rubber and liquid silicone rubber systems.

    Typical applications include two-part RTV silicone, LSR, specialty silicone coatings, encapsulants, sealants, and industrial formulations requiring vinyl reactivity.

    Vinyl Silicone Oil is a polymer family rather than a single fixed molecule.

    Viscosity affects processing and final elastomer properties, while vinyl content controls reactive group availability for addition-cure or modification systems.

    The two parameters should be selected together according to the cure chemistry and target formulation.

    Hydrogen Silicone Oil provides Si-H groups that react with vinyl groups during hydrosilylation; the two are complementary, not interchangeable.

    Confirm viscosity grade, vinyl content, appearance, and offered grade before ordering.

    Store in tightly closed, clean containers in a cool, dry, well-ventilated area away from moisture, contamination, direct sunlight, excessive heat, and incompatible curing agents.

    Maintain package integrity during storage and transport.

    Use appropriate handling practices for a liquid silicone fluid, confirm packaging and transport requirements, and follow the current SDS.

    Every batch is checked for appearance, viscosity, vinyl content, volatile content, and relevant trace impurities, with COA/TDS/SDS supplied per grade.

    Confirm viscosity, vinyl content, appearance, packaging, and grade as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Vinyl Silicone Oil CAS 68083-19-2?

      A: Vinyl Silicone Oil is a vinyl-functional polydimethylsiloxane fluid, also known as vinyl-terminated PDMS or ViPDMS, with CAS 68083-19-2 and EC 614-275-5. It is supplied as a colorless to transparent liquid in different viscosity grades and is used as a reactive silicone raw material.
    • Q:

      Where is Vinyl Silicone Oil mainly used?

      A: It is mainly used as a base polymer or reactive component in addition-cure silicone rubber and liquid silicone rubber systems. Typical applications include two-part RTV silicone, LSR, specialty silicone coatings, encapsulants, sealants, and industrial formulations requiring vinyl reactivity.
    • Q:

      Why do viscosity and vinyl content matter?

      A: Vinyl Silicone Oil is a polymer family rather than a single fixed molecule. Viscosity affects processing and final elastomer properties, while vinyl content controls reactive group availability for addition-cure or modification systems. The two parameters should be selected together according to the cure chemistry and target formulation.
    • Q:

      How does Vinyl Silicone Oil differ from Hydrogen Silicone Oil?

      A: Vinyl Silicone Oil provides vinyl groups and is used as the base polymer or vinyl-functional component. Hydrogen Silicone Oil provides Si-H groups that react with vinyl groups during hydrosilylation. They are complementary silicone fluids in addition-cure systems, not interchangeable materials.
    • Q:

      How should Vinyl Silicone Oil be stored and handled?

      A: Store it in tightly closed, clean containers in a cool, dry, well-ventilated area away from moisture, contamination, direct sunlight, excessive heat, and incompatible curing agents. Maintain package integrity during storage and transport, and use appropriate handling practices for a liquid silicone fluid.
