Name | SILICONE RESIN |
Synonyms | SILICONE RESIN SYLGARD(R) 184 SILICONE ELASTOMER KIT |
EINECS | 946-216-7 |
Physical and Chemical Properties | Chemical properties are colorless to light gray transparent or translucent viscous liquid or paste, and those containing trace powdered silica are white to translucent. Odorless, almost odorless, neutral, non-volatile, non-burning, stable to heat, and in a larger temperature range, the viscosity changes very little. Very poor conductivity. It doesn't work for most chemicals. The defoaming power is strong. The viscosity of general commodities is (100~1100)× 10-6m2/s. Soluble in benzene, toluene, carbon tetrachloride, chloroform and ether, slightly soluble in acetone, ethanol, insoluble in methanol, propylene glycol, liquid paraffin, glycerin, vegetable oil and water. |
Use | Use 1, defoaming agent. Mainly used in monosodium glutamate, wine, soy sauce and other fermentation industry. When adding an appropriate amount of lactic acid, it can be applied to the inner wall of the fermentation tank and the impeller, and it can also be diluted with 5 to 10 times of water and then added to the foamed liquid surface. 2, used for the preparation of medical pressure sensitive adhesive, drug transdermal absorbent, drug controlled release preparation, Beauty cosmetics, etc |
Dimethylsilicon dichloride and trimethylsilicon chloride are obtained by the reaction of silicon and methyl chloride, which are decomposed by adding water to obtain trimethylsilicon hydroxide, and then polymerized in the presence of a catalyst.
It is made by mixing 5% ~ 15% anhydrous silicic acid fine powder in silicone oil.
