LK-SIL 100T (10 cSt - 2,000,000 cSt) Silicone Fluids

Versatile Industrial-Grade Polydimethylsiloxane (PDMS) Fluids

LK-SIL 100T is a high-performance industrial-grade silicone fluid composed of polydimethylsiloxane (PDMS). Offered in a wide viscosity range from 10 cSt to 2,000,000 cSt this product line delivers exceptional thermal, oxidative, and shear stability, making it ideal for demanding industrial applications.
These fluids are clear, have a low characteristic odor, and are soluble in a wide range of organic solvents. The unique silicon-oxygen backbone of LK-SIL 100T provides performance advantages that surpass those of petroleum-based fluids.

Key features:

  • Low Viscosity/Temperature Coefficient – Ensures minimal viscosity change over a wide temperature range.
  • Thermal Stability – Operates efficiently between -52°C to 200°C (short-term use possible beyond this).
  • Oxidation Stability – Performs consistently up to 200°C without sludge formation.
  • Chemical Inertness – Inert to most chemicals, making it suitable for sensitive systems.
  • Low Flammability – Flash point: 250–300°C, Autoignition: 438–460°C.
  • Low Surface Tension – Promotes excellent spreading and wetting properties.
  • Shear Stability – Up to 20x more shear-resistant than petroleum-based oils.
  • Non-Corrosive – No acid-forming constituents; safe for metals and sensitive surfaces.
  • High Compressibility – Suitable for hydraulic systems requiring shock absorption and pressure control.
