Dimethicone- ▸ Cosmetic vehicle / spreading agent: high spreadability and subtle skin lubricity with a longer-lasting film than 5 cSt
- ▸ Electrical insulating / dielectric & coolant fluid for transformers, condensers and breaker insulation
- ▸ Antifoam / defoamer in plastics and latex manufacture
- ▸ Mold release and resin slip additive — adds lubricity to synthetic resins
- ▸ Paint flow aid: low surface tension improves flow and reduces orange-peel
Mid- and high-viscosity polydimethylsiloxane fluids (>= 5 cSt) are reported as not meeting GHS hazard-classification criteria. The grade-specific SDS governs. A full SDS is supplied with every shipment and on request; hazard status is confirmed against the grade-specific SDS.
Silicone Oil 10 cSt is the broadest low-viscosity workhorse. It keeps the fast spreading and low surface tension of the thin grades but is less volatile and forms a more persistent film, so it carries the widest low-end application set: a cosmetic spreading vehicle, a dielectric and bath fluid, a defoamer, a mold-release and resin slip additive, and a paint flow aid.
Frequently Asked Questions
What does cSt mean in silicone oil?
cSt stands for centistokes, the unit of kinematic viscosity. For silicone oil (PDMS, CAS 9006-65-9) it indicates how thin or thick the fluid is at a reference temperature; 10 cSt is a low-viscosity, free-flowing grade, while higher cSt numbers are progressively thicker.
What is the viscosity of silicone oil 10 cSt?
Silicone Oil 10 cSt has a nominal kinematic viscosity of 10 centistokes, a relatively low-viscosity, free-flowing dimethicone fluid. Confirm the exact value and reference temperature on the lot CoA when ordering.
What is silicone oil 10 cSt used for?
Low-viscosity PDMS grades like 10 cSt are used where a thin, spreadable silicone fluid is needed, such as in release, lubrication, and personal-care formulation. Suitability depends on your application, so match the grade to your formulation requirements.
What is the CAS number for silicone oil 10 cSt?
Silicone oil (dimethicone, PDMS) carries CAS 9006-65-9 with the repeating-unit formula (C2H6OSi)n. The 10 cSt designation refers to the viscosity grade, not a separate CAS number; all dimethicone viscosity grades share this CAS.
Can silicone oil 10 cSt be supplied in bulk?
Yes. RawSource supplies 10 cSt silicone oil in drum, tote, and IBC quantities to manufacturers. Request a bulk quote with your target volume and packaging; CoA and SDS are available on request.
