Dimethicone- ▸ Personal-care barrier / de-soaping film: a uniform protective film in hand creams and lotions at as little as 0.1%
- ▸ Polish glide fraction: the low-viscosity lubricant in a polish blend that eases application and rub-out
- ▸ Release agent / mold release with a coherent, low-migration film
- ▸ Heat-resistant industrial lubricant and hydraulic-fluid component (flash point >275 °C)
- ▸ Multi-function additive: antifoam, water-repellent, liquid dielectric and heat-transfer oil
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 100 cSt is the balanced grade: mid viscosity gives a coherent, more uniform film than the thin grades without the drag of the heavy ones. It is marketed directly into personal-care barrier films and into polish blends as the low-viscosity glide fraction, and serves as a release agent, heat-resistant lubricant and multi-function additive.
Frequently Asked Questions
What is 100 cSt silicone fluid used for?
100 cSt silicone fluid (dimethicone / PDMS) is the balanced mid grade: a personal-care barrier film, the glide fraction in polish blends, a release agent, a heat-resistant lubricant for polymer parts, and a multi-function antifoam / dielectric / water-repellent additive. Its mid viscosity gives a coherent, uniform film.
Is 100 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); 100 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 100 cSt silicone oil flammable?
No. At a flash point of ≥ 315 °C (open cup) the 100 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.
