SILISIL ·

SILISIL Silicone Oil 300'000 cSt is an ultra-viscous PDMS for high-end antifoam and premium conditioner.

SILISIL Silicone Oils are high-purity linear polydimethylsiloxane (PDMS) liquids with a purity of 100%. Their viscosity of 300,000 cSt defines their range of applications — from lubrication and release agents to hydraulic functions and specialized care and industrial applications.

Special Premium Class

300,000 cSt is the intermediate class for applications with the highest service life requirements — a very effective antifoam and high-end conditioner base.

Important instructions

Storage & Handling
Store in the unopened original container in a dry, cool place (ideally below 60°C). Avoid contact with eyes. Consult the SDS before opening.
Solvent compatibility
Soluble in aromatic, aliphatic, and chlorinated solvents. Immiscible with water and alcohols.
Release agent effect before painting
Standard PDMS prevents paint adhesion to subsequent coatings. For paintable applications, choose SILISIL Silicone Oil – Paintable Grade.
Application advice
SILITECH can advise you on the optimal viscosity choice for your application — contact us for a consultation.

Frequently asked questions about SILISIL Silicone Oil 300,000 cSt

Practical application and design questions — answered by SILITECH.

SILISIL Silicone Oil 300,000 cSt: Ultra-viscous PDMS for high-end antifoam and premium conditioner. Main applications include antifoam in the petroleum and petrochemical industries, high-end conditioner, and premium care products.

PDMS (polydimethylsiloxane) is a linear silicone fluid that combines high thermal stability, low surface tension, very good dielectric properties, and a wide temperature range. The viscosity (measured in centistokes, cSt) determines the application range—low viscosities are suitable for volatile applications and lubrication, high viscosities for damping and conditioning.

SILISIL silicone oils are soluble in aromatic, aliphatic, and chlorinated solvents (e.g., toluene, xylene, hexane, diesel). They are immiscible with water and alcohols. For anti-foaming applications, highly viscous PDMS are diluted in hydrocarbon solvents and applied using a metering pump.

Store in the unopened original container at room temperature (ideally below 60°C). Avoid contact with eyes. SILISIL Silicone Oils are generally non-toxic, odorless, and tasteless; however, consult the Safety Data Sheet (SDS), which is available in the "Documents" tab.

Viscosity determines the application. 300,000 cSt is optimal for: antifoam, petroleum & petrochemicals, and similar application profiles. For other application characteristics, you will find related viscosities in the comparison table above — if you are unsure, we will be happy to advise you on your specific application.
