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 is 10 cSt silicone fluid used for?
10 cSt silicone fluid (dimethicone / PDMS) is the broadest low-viscosity grade: a cosmetic spreading vehicle, a dielectric and bath fluid, a defoamer in plastics and latex, a mold-release and resin slip additive, and a paint flow aid. It keeps low-viscosity spreading but forms a more persistent film than 5 cSt.
Is 10 cSt silicone fluid the same as dimethicone or silicone oil?
Yes — silicone fluid, silicone oil, dimethicone and PDMS all refer to the same linear polydimethylsiloxane (CAS 9006-65-9); 10 cSt is the viscosity grade. Because it is a polymer rather than a single molecule, properties are reported per grade rather than as one fixed molecular weight.
Is 10 cSt silicone oil flammable?
No. At a flash point of 163 °C (open cup) the 10 cSt grade is not classified as flammable, and mid- to high-viscosity PDMS is not otherwise GHS-classified. Only the volatile sub-5 cSt grades (and discrete volatiles like MM) are flammable. A grade-specific SDS ships with every order.
