Overview of Polydimethylsiloxane Vinyl Terminated
Vinyl terminated Polydimethylsiloxane (Vi-PDMS and 68083-19-2, CAS) is a silicone reactive fluid that contains vinyl groups on the chain's ends. This allows hydrosilylation crosslinking to make high-strength silicon Elastomers. Polydimethylsiloxane
vinyl terminated structure features repeating [-Si(CH3)2O-] units capped with -CH=CH2, offering viscosities from 100-100,000 cSt, low volatiles, and excellent weather/chemical resistance. Polydimethylsiloxane vinyl terminated uses include base polymer for addition-cure RTV silicones, LSR, gels, and modifiers for coatings/adhesives.
Applications of Polydimethylsiloxane Vinyl Terminated
Silicone Rubber & Elastomers
Serves as base for platinum-cure liquid silicone rubber (LSR), HTV silicone, and RTV sealants/gels, improving tear strength, hardness, and electrical insulation in gaskets, molds, electronics. Use with Zinc Stearate for processing.
Coatings, Adhesives & Composites
Modifies polyurethanes, acrylics, epoxies for UV/weather resistance, low modulus, and toughness; in composites for reinforcement. Enhance resins with Cobalt Octoate or 1,4-Butanediol.
Other Industrial Uses
In lubricants, defoamers, medical devices, aerospace seals; check categories, applications, homepage.
Safety & Handling Guidelines
- Store cool, dry, sealed away from strong acids/bases, metals, oxidizers; stable under inert conditions.
- Wear gloves, goggles; avoid prolonged skin/eye contact or vapors—may irritate; low toxicity.
- Combustible; dispose per regulations.
