Silicone fluids are generally colorless transparent liquids. They exhibit excellent resistance to heat, cold, and moisture. There is also little viscosity change in silicone fluids over a wide temperature range, and they have outstanding electrical properties. In addition, they are notable for their characteristics of mold-releasability, water repellency, lubricity, and defoaming properties.
Silicone fluids have outstanding stability against thermal oxidation.
Silicone fluids withstand low temperatures well. Methylphenyl silicone fluid, formulated for low temperature applications, maintains flowability even at -65°C.
There is little change in viscosity over a wide temperature range.
Silicone fluids are almost totally chemically inactive. At room temperature, they show almost no effects from alkali solutions (up to 10%) or acidic solutions (up to 30%).
Silicone fluids have almost no adverse effects on metals and many other materials.
Silicone fluids have much lower surface tension than water and other common synthetic oils.
