Acidic Colloidal Silica For Casting

With a sole aim in delivering quality products, we are the prominent Exporter & Manufacturer of Acidic Colloidal Silica For Casting in Wuhan, Hubei, China.
1.Silicon sol have larger adsorption capacity: silicon sol countless network structure, under certain conditions, have certain adsorption of inorganic and organic matter.
2.Silica sol has bigger specific surface area, usually is: 150-300 m2 / g.
3.Colloidal silica has a good bonding performance: because the micelle size uniform, in 10 to 20 m/u, its drying to produce specific bond strength, but strength is very small, if the silicon sol to join fiber or granular materials, and then drying curing can be a solid gel structure.Will have larger bonding performance.(an average of 46.7 kg/cm2)
4.Silica sol has good heat resistance, resistance to high temperature about 1600 a .
5.Silica sol has good hydrophilicity and intense hate oily: any concentration can be diluted with distilled water or deionized water and the increase of the degree of dilution stability enhancement, added to the organic substances and all kinds of metal ions, and can produce hate oily.
6.In addition, silicon sol is highly fragmented, with good abrasion resistance and good pervious to light quality, so you can do good dispersing agent, preservative, flocculant, coolant, etc.
