3. Properties and Uses：
It is colorless transparent or light yellow transparent liquid. Compared with methyl silicone oil, it has the better resistance in the high and low temperature (-70 ~ 300 ℃), and the properties of lubricity, mold unloading and electrical insulation. It is small in temperature viscosity coefficient and volatility. Compression rate and the surface tension is high. It is well in miscibility with other organic resin . The UV-resistant properties is unique. So it does for high temperature lubrication, damping, stripping, skin, soft handle, heat carrier, etc..

4. Packing, Storage, and Handling：
Packed in clean dry 200kg iron drums or 25 and 50kg plastic barrels. It prevents from moisture and mixing of impurities such as acid-base. Stored in a shade and dry place, and the temperature should be controlled at 0℃-40℃ to prevent freezing. Handing according to non-hazardous substance
