Hydrophobic fumed silica is generally a post processed product. You can use different types of gas phase or precipitated silica as raw material, by the reaction of silicon alkyl groups with suitable compounds; this product is due to hydrophobic surface hydrolysis of methyl groups not connected.
Unlike the original hydrophilic silica, hydrophobic fumed silica cannot be wetted by water. Although the density of hydrophobic fumed silica is greater than that of water, they can float on water. After hydrophobic, the amount of water absorbed will be significantly lower than that of the original hydrophilic silicon.
The surface treatment of fumed silica was adopted, and its technical performance can be optimized in some specific applications, which can effectively improve the rheological properties of many liquid polymer systems, especially in the epoxy resin system
