Application of methyl long chain alkyl silicone oil

Methyl long-chain alkyl silicone oil is mainly used in the preparation of greases and ointments, mold release agents, coating additives, cosmetics and resin modification.

1. Application of grease and grease

The methyl long chain alkyl silicone oil has good lubricity and wear resistance. It can be used for a long time in the range of -50 °C - 150 °C. Aluminum is a metal that is difficult to lubricate with petroleum lubricants. It is usually added with vinyl stearate as a boundary lubrication additive to form a special aluminum lubricant.

2, the application of liquid transmission fluid

Methyl long-chain alkyl silicone oil is mixed with α-olefin oligomer to form a liquid transmission liquid with a wide temperature range and high flash point temperature, which is used in aircraft, military vehicles and mechanical equipment for cold belt use. Such as methyl long-chain alkyl silicone oil and α-pinene trimer mixed with the same amount of transmission fluid, its flash point 215 ° C, ignition point 213 ° C, 25 ° C viscosity 18cs.

3. Release agent for plastic and rubber products

Methyl long-chain alkyl silicon is used as a release agent for plastics and rubber products. It is generally diluted to 2-10% in toluene, industrial gasoline, etc., or used as an aerosol or emulsion. The plastic and rubber products after demolding can be printed, vapor-deposited, hot pressed and painted on the surface. However, the products of the general dimethyl silicone oil release agent are difficult to print, vapor, heat and paint on the surface.

4, the raw materials of cosmetics

The use of long-chain alkyl-modified silicone oil to prepare skin care products has the effect of keeping the skin moist, can relieve the symptoms of dry skin and maintain the softness of the skin.

5, plastic modification and coating additives

Methyl long-chain alkyl silicone oil has good compatibility with synthetic resin, and it can improve the boundary lubrication property of plastic products as an additive for various plastics. Additives for coatings improve pigment dispersion, leveling and abrasion resistance.
