SILISIL ·

SILISIL Silicone Oil 3 cSt is a low-viscosity PDMS for cosmetics, lubrication, and electrical insulation.

SILISIL Silicone Oils are high-purity linear polydimethylsiloxane (PDMS) liquids with a purity of 100%. Their viscosity of 3 cSt defines their application range—from lubrication and release agents to hydraulic functions and specialized care and industrial applications.

Very low surface tension

3 cSt combines low viscosity with good lubricity — ideal for applications requiring spreading and lubrication simultaneously, e.g., elastomer-on-metal lubrication in accelerometers and micromechanics.

What distinguishes SILISIL Silicone Oil 3 cSt

Excellent spread
Low surface tension ensures a uniform, thin layer on any surface.
Lubricating effect
Lubricates lightweight plastic/elastomer compounds with minimal application.
Dielectric insulation
High resistance and dielectric strength for electronic applications.
Low volatility
Evaporates more slowly than 0.65 or 2 cSt — longer duration of action.
Low-temperature resistance
Remains liquid even at -65 °C — suitable for refrigeration and deep-freezing technology.
Chemically inert and non-toxic
Safe for use in consumer goods applications, near food products and cosmetics.

What is SILISIL Silicone Oil 3 cSt used for?

Cosmetics & Personal Care
Skincare products with a silky, non-greasy feel — hand, face and body lotion.
Micromechanical lubrication
Accelerometers, microswitches and precision mechanics with small friction pairs.
Dielectric impregnation
Capacitor winding impregnation with low loss factor and high dielectric strength.
Low-temperature hydraulics
Hydraulics in cooling and deep-freeze systems with operating temperatures below 0 °C.
Release agent with moderate service life
The release film lasts slightly longer than with very low-viscosity variants.
Elastomer lubrication
Rubber-on-metal friction partners in sensors, actuators and control units.

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.

Frequently asked questions about SILISIL Silicone Oil 3 cSt

Practical application and design questions — answered by SILITECH.

SILISIL Silicone Oil 3 cSt: Low-viscosity PDMS for cosmetics, lubrication, and electrical insulation. Main applications include cosmetics and personal care, micromechanical lubrication, and dielectric impregnation.

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.

The viscosity determines the application. 3 cSt is optimal for cosmetics & personal care 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.
