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.
Features
Heat resistance
Silicone fluids have outstanding stability against thermal oxidation.
Cold resistance
Silicone fluids withstand low temperatures well. Methylphenyl silicone fluid, formulated for low temperature applications, maintains flowability even at -65°C.
Viscosity stability
There is little change in viscosity over a wide temperature range.
Chemical stability
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%).
Non-corrosive and little effect on other materials
Silicone fluids have almost no adverse effects on metals and many other materials.
Low surface tension
Silicone fluids have much lower surface tension than water and other common synthetic oils.
