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 silicone oil 12500 cSt used for?
Silicone Oil 12,500 cSt is a high-viscosity PDMS (dimethicone) fluid used in damping, heavy lubrication, release, and specialty formulation where a thick, slow-flowing silicone with substantial film body is required. Match the viscosity grade to your specific application.
What is silicone fluid 12500 cSt?
It is dimethicone (PDMS, CAS 9006-65-9) supplied at a nominal kinematic viscosity of 12,500 centistokes, a high-viscosity grade. The 12,500 cSt figure is the viscosity specification; confirm the exact value and reference temperature on the lot CoA.
What does cSt mean in silicone oil?
cSt is centistokes, the unit of kinematic viscosity. For silicone oil (PDMS, CAS 9006-65-9) it indicates fluid thickness; 12,500 cSt is a high-viscosity grade, much thicker than common 100-1,000 cSt fluids.
What is the CAS number for silicone oil 12500 cSt?
Silicone oil (dimethicone, PDMS) carries CAS 9006-65-9 with repeating-unit formula (C2H6OSi)n. The 12,500 cSt label is the viscosity grade, not a distinct CAS; all dimethicone viscosity grades share this number.
Can silicone oil 12500 cSt be supplied in bulk?
Yes. RawSource supplies 12,500 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.
