It can be widely used in skin and hand cream, skin cleaner, sunscreen products, shaving cream,deodorant, bath foam and hair conditioner, also can be made into polish and defoamer. It has excellent consistency with all kind of ingredient of cosmetics and dissolving capacity to vitamin, hormone, bactericide and anti-inflammatory drugs. With its hydrophobicity, it can form a lamina on the skin surface so as to keep vitamin and drugs stay on the skin surface for a long time. It has stable effect of nutrition and can make hair soft and smooth, adding gloss as well. With its excellent adaptability to extreme weather, translucency, electrical property, moisture resistance and chemical stability, it also can be made release agent of plastic or rubber materials. Viscosity: 350
At room temperature, it can react with crosslinking agents in the presence of catalysts, to form a reaction product, which has many excellent properties such as keeping good elasticity from -60â?? to 20 excellent electrical property chemical stability and good resistance to water, odor, weather. Therefore, it can be widely used in many industries, such as electronics, semiconductors, autos, mechanicals, fabric, plastic, printing, construction, etc. Viscosity 25,mPa : 2 000/5 000/20 000/50 000/80 000
With the action of metal salt catalyst, it can form a durable waterproof membrane with good hydrophobic and high contact angle. It can be widely used as release agent in rubber and plastic industry, antirust agent for metal and anti-adhesive agent for paper and packing material. It can increase the performance of tear strength, abrasion resistance, crease-resist, anti-fouling, waterproof, ironing resistance and sewability without influencing the original breathability of the fabric. The optical glass coated with it will have high light transmittance, excellent mildew and moisture resistance.
It widely used in cosmetics and body care products, Such as skin care, sunscreen, makeup, hair conditioning products,good compatibility with most of the alcohol and other cosmetic solvents. Be directly used as the carrier, the main raw material, also can be used as an additive; and be used in aqueous systems by the method of emulsification.
It is colorless, inflammable, and can not dissolve in water, but dissolve in organic solvents such as benzene, etc. It can be used to synthesize organic silicon polymer by acid or alkali catalysis to manufacture silicone oil, silicone rubber, etc. It can also be used directly as treating agent for rubber stuffing and the raw material for cosmetic.
