SILISIL Silicone Oil 3 cSt — Ultra-low-viscosity PDMS silicone oil
SILISIL Silicone Oil 3 cSt is a nearly water-clear, ultra-low-viscosity, low-molecular-weight polydimethylsiloxane (PDMS). It is characterized by high spreadability, very low surface energy, and controlled volatility—making it ideal as a carrier fluid for formulations designed to leave a dry, non-greasy film after application.
Key features
| Viscosity at 25 °C | 3 cSt (3 mPa·s) |
| Density at 25 °C | 0.898 g/cm³ |
| Flash point (open cup) | 85 °C |
| pour point | -80 °C |
| surface tension | 19.3 mN/m |
| Polymer type | Polydimethylsiloxane (PDMS), linear |
All other properties (refractive index, thermal conductivity, dielectric properties, etc.) are listed as structured product attributes on this page and can be filtered in the shop. Please refer to the technical data sheet (TDS) in the documents section for the official values.
product benefits
- Easy application on virtually all substrates
- Very low surface tension — ideal for ultra-fine dispersion
- Lightweight formula — leaves a thin, non-greasy film
- Chemically inert and odorless
- Excellent wetting of metals, glass, and plastics
- Electrically insulating and non-conductive
Typical Applications by Industry
- Cosmetics and Pharmaceuticals: Carrier fluid in skin care emulsions, antiperspirants, and volatile care formulations
- Precision Engineering: Lubrication of Watch Movements, Measuring Instruments, and Precision Bearings
- Silicone Industry: Thinners and Viscosity Modifiers for 2-Component RTV Systems
- Surface finish: Dry release agent on polymer and elastomer components
- Hydraulics: Working fluid for low-temperature applications with high fluidity
Processing and Compatibility
- Compatible with most organic solvents (aromatic and aliphatic hydrocarbons, ethers, esters)
- Emulsifiable using standard emulsifiers and techniques (rotor-stator, high-pressure homogenization)
- Typical dosage as a surface additive: 0.1–1%
- In formulated or cosmetic products: 1–10%, depending on the formulation
- Inmiscible with water and highly polar solvents (methanol, glycerin)
Storage, Handling, and Shelf Life
- Store in original containers, in a dry place, protected from direct sunlight, at temperatures below 60 °C
- Unopened products typically remain stable for years—the exact shelf life is specified in the TDS
- Close tightly after opening to prevent moisture from entering
- Avoid eye contact — mandatory information in the safety data sheet (SDS)
Available sizes

Frequently Asked Questions About SILISIL Silicone Oil 3 cSt
The most important answers regarding applications, features, and availability.
SILISIL Silicone Oil 3 cSt is an ultra-low-viscosity polydimethylsiloxane and is particularly suitable as a carrier fluid in cosmetic and skincare formulations, for precision lubrication of precision mechanical parts, and as a diluent for RTV silicone systems.
The unique feature of SILISIL Silicone Oil 3 cSt is its combination of very low surface tension, low viscosity, and controlled volatility. The product spreads on virtually all substrates, leaves a non-greasy film, and evaporates in a thin layer with minimal residue. The exact specifications—in particular viscosity (3 cSt), density (0.898 g/cm³), flash point (85 °C), and pour point (-80 °C)—are also listed as product attributes and can be filtered in the shop.
Yes. SILISIL Silicone Oil 3 cSt is an excellent electrical insulator with a breakdown strength of approximately 14 kV/mm, a dielectric constant of about 2.6, and a specific volume resistivity in the order of 10¹⁵ Ω·cm. This makes the product particularly suitable for dielectric and electronic impregnation applications.
SILISIL Silicone Oil 3 cSt is typically available from our Swiss warehouse in 1 kg, 5 kg, 25 kg, 200 kg, and 1000 kg sizes. Other sizes and packaging options are available upon request to meet customer specifications—we provide a free sample for preliminary testing.
