Dimethicone- ▸ Polish active ingredient: high-gloss automotive, furniture, metal and specialty polishes with easy rub-out and buffing
- ▸ Damping medium and hydraulic stabilizer — high compressibility and damping action
- ▸ Electrical insulating / dielectric fluid
- ▸ Antifoam / foam control for petroleum production and refinery operations
- ▸ Elastomer / plastics lubricant, mold release and leather/textile finishing — durable, tenacious film
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 12,500 cSt is promoted from polish additive to polish ACTIVE: its high viscosity builds a durable, high-gloss film with depth of gloss, and it is the heavy partner in the classic 100:12,500 polish blend. It is also a recognized damping / hydraulic-stabilizer grade, a dielectric fluid and a foam-control fluid.
Frequently Asked Questions
What is 12,500 cSt silicone fluid used for?
12,500 cSt silicone fluid (dimethicone / PDMS) is a polish ACTIVE for high-gloss automotive, furniture and metal polishes (the heavy partner in the 100:12,500 blend), plus a damping / hydraulic-stabilizer fluid, a dielectric and foam-control fluid, and a durable elastomer/plastics lubricant and mold release.
Is 12,500 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); 12,500 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 12,500 cSt silicone oil flammable?
No. At a flash point of ≥ 315 °C (open cup) the 12,500 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.
