Vinyl Silicone Oil CAS 68083-19-2
Vinyl Silicone Oil (CAS 68083-19-2) is a vinyl terminated polydimethylsiloxane, a clear liquid with vinyl groups at the chain ends. Vinyl groups add to hydrogen silicone under a catalyst, curing into a flexible network without byproducts. Rubber plants use it as the base for addition cure liquid silicone rubber, gels and potting. It also serves LED encapsulation, release coatings, ink additives and polymer modification. UATChem supplies grades in plastic drums, steel drums and IBCs, with COA, TDS and SDS on request.

What Vinyl Silicone Oil Is
Vinyl Silicone Oil, or Vi-PDMS, is PDMS with vinyl at both ends, CAS 68083-19-2, sold as clear liquid. The backbone gives heat and cold resistance and low tension, while terminal vinyl groups give a clean cure site. In addition cure vinyl groups react with hydrogen silicone under platinum catalyst, linking into an elastomer. It is the base polymer for liquid silicone rubber and potting. UATChem supplies it, with viscosity and vinyl on COA, TDS.
Silicone Rubber, Potting, Release and Coating Uses
- Addition cure rubber. It is the base polymer for liquid silicone rubber, gels and soft elastomers.
- Electronic and LED. It serves potting compounds and LED encapsulation with electrical stability.
- Release coatings. It forms release and anti stick surfaces on paper and film.
- Ink, paint and modification. It adds slip and durability to ink and coatings and modifies polymers.

FAQ
Q: What is vinyl silicone oil used for?
A: It is the base polymer for addition cure silicone rubber, gels and potting, and serves LED encapsulation and release coatings.
Q: How does vinyl silicone oil cure?
A: The vinyl groups react with hydrogen silicone under a platinum catalyst, linking chains into an elastomer without byproducts.
Q: How is vinyl silicone oil packed?
A: UATChem supplies the fluid in plastic drums, steel drums and IBC totes, sealed away from moisture, with COA, TDS and SDS.
Q: Is vinyl silicone oil the same as dimethyl silicone oil?
A: It adds vinyl groups to PDMS, so it addition cures, while dimethyl silicone oil stays nonreactive, with data on COA and TDS.
