Silico MF2010-20 cSt Silicone Fluid
Introduction
Silico® MF2010-20 cSt Silicone Fluid is a high-purity, linear polydimethylsiloxane (PDMS) silicone oil with a nominal viscosity of 20 centistokes (cSt) at 25 °C. It is a transparent, colorless, chemically inert fluid developed for industrial lubrication, electrical insulation, heat transfer, surface wetting, and precision applications where consistent rheology and thermal stability are critical.
This product combines the advantages of silicone chemistry — including low surface tension, low temperature fluidity, and wide operating temperature range — with industrial-grade manufacturing controls to ensure performance and reliability.
