A. Hydroxy silicone oil
Hydroxy silicone oil is a colorless and transparent liquid, with excellent electrical insulation and high and low temperature resistance, high flash point, low freezing point, can be used for a long time under the conditions of -50ºC~+250ºC, low viscosity-temperature coefficient, high compression rate and low surface tension , Good water-repellent and moisture-proof, chemically inert and physiologically inert.
Uses: It can be mixed with cross-linking agent and catalyst and can be cured at room temperature. It is the main component of leather slip agent. It can also be used as leather brightener, release agent, etc.
B. Hydrogen-containing silicone oil
Hydrogen-containing silicone oil, under the action of a metal catalyst, can be cross-linked at an appropriate temperature to form a waterproof film on the surface of various substrates. It is widely used as fabric, fire extinguishing agent (dry powder), paper, metal, leather, wood, glass, cement , Ceramics, marble waterproofing agent, anti-sticking agent or anti-corrosion agent, etc.

C. Methyl silicone oil
Methyl silicone oil is colorless, odorless and not volatile; it is insoluble in water, methanol, glycol, and can be miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene. It has a small vapor pressure and a high flash Point and burn point. Methyl silicone oil has excellent heat resistance, electrical insulation, weather resistance, hydrophobicity, physiological inertness and small surface tension. It also has a low viscosity-temperature coefficient and high compression resistance.
use:
1. Used as insulation, lubrication, shockproof, dustproof oil, dielectric fluid and heat carrier.
2. Used as an additive for defoaming, film release, paint and daily cosmetics.
3. It is used for the treatment of sewing thread to increase lubrication, and it can be used in high-speed sewing machine without thread.
4. Used for the soft finishing of fabrics, increase the lubricity of the fabrics, and increase the smoothness, fullness and elasticity of the fabrics.
Methyl silicone oil is widely used in electronic appliances, building materials, motor manufacturing, transportation, petrochemicals, textiles, printing and dyeing, thread making, various polyester and polyester cotton, polyester rayon textiles to improve the smoothness and elasticity of the finishing and medicine and health , Aviation research and military technology.
