Dimethicone is a transparent, colorless, tasteless, odorless and non-toxic oily liquid. According to the supply of dimethyl silicone oil, it has the characteristics of high flash point, low freezing point, good thermal stability, and high and low temperature resistance. It can be used for a long time at -50℃~+180℃. If it is isolated from air or in an inert gas, the temperature can reach 200℃. The surface silicon tension of the oil is very small, the compressibility is large, the shear resistance is good, the viscosity-temperature coefficient is small, and the dielectric loss is small; it is resistant to arcs, corona, and is not flammable; it is hydrophobic and moisture-proof, and it also has good physiological inertness. Dimethicone is non-toxic to the human body and is not decomposed by body fluids, so it is also widely used in medical and health care.
Dimethicone can be used as an additive for paints and inks:
If it can be used as a gloss enhancer for paint, add a small amount of silicone oil to the paint to make the paint It does not float or wrinkle and improves the brightness of the paint film;
Add a small amount of silicone oil to the ink to improve the printing quality;
Add a small amount of silicone oil to the polishing oil (such as automotive Glazing oil), which can increase brightness, protect the paint film, and has excellent waterproof effect.
Methyl silicone oil can be used as a lubricant:
Dimethyl silicone oil is suitable as a lubricant for rubber, plastic bearings and gears. It can also be used as a lubricant for rolling friction between steel and steel at high temperatures, or for friction between steel and other metals. However, since the lubricating properties of methyl silicone oil are not particularly good at room temperature, it is not recommended as a lubricant at room temperature. Lubricant between metals
