Understanding the CAS Number of Vinyl Terminated Silicone Fluid

Vinyl terminated silicone fluid, a cornerstone in industrial and commercial applications, is identified by its unique chemical structure and reactive properties. For professionals seeking precise technical data or procurement guidance, understanding its CAS number and functional characteristics is critical. This article explores the CAS identifier, applications, and performance advantages of vinyl terminated silicone fluids, with insights into how brands like ​Biyuan​ deliver high-performance solutions tailored to diverse needs.


CAS Number Identification

The CAS (Chemical Abstracts Service) number for vinyl terminated silicone fluid is ​68083-19-2. This identifier corresponds to a class of polydimethylsiloxane polymers terminated with reactive vinyl groups (-CH=CH₂), enabling crosslinking reactions essential for applications in elastomers, sealants, and coatings .


Chemical Properties & Functional Advantages

  1. Reactive Vinyl Groups
    The terminal vinyl groups allow addition-curing reactions with hydrogen-containing crosslinkers (e.g., hydrosilanes) and platinum catalysts. This enables precise control over curing conditions (ambient or elevated temperatures) and enhances material durability .
  2. Viscosity Customization
    Available in a broad viscosity range (100–100,000 cSt), these fluids cater to applications demanding flexibility in processing. For instance:
    • Low-viscosity grades (100–500 cSt) serve as diluents in silicone rubber formulations.
    • High-viscosity grades (10,000–100,000 cSt) are ideal for mold-making and structural adhesives .
  3. Thermal & Chemical Stability
    Resistant to extreme temperatures (-50°C to 300°C) and inert to most chemicals, vinyl terminated silicone fluids maintain performance in harsh environments, making them suitable for automotive, aerospace, and electronics sectors .

Key Applications

  1. Silicone Elastomers & Rubbers
    As a base polymer for RTV-2 (room-temperature vulcanizing) and LSR (liquid silicone rubber), these fluids form the backbone of products like medical tubing, electrical insulators, and automotive seals .
  2. Coatings & Release Agents
    Their low surface tension and hydrophobic properties make them ideal for anti-stick coatings, protective films, and mold-release agents in food packaging and industrial machinery .
  3. Electronics Encapsulation
    Used in potting compounds for circuit boards, vinyl terminated silicone fluids provide moisture resistance and thermal management, critical for durability in humid or high-temperature settings .
