1. Introduction of Hydrophilic SiO2 Silicon Dioxide
Hydrophilic fumed silica is manufactured by hydrolysing volatile chlorosilanes in an oxyhydrogen flame. The loose white powder consists of highly pure amorphous silicon dioxide. Hydrophilic silica is wetted by water and can be dispersed in water. Hydrophobic silica is produced by the chemical reaction of hydrophilic silica with reactive silanes. It has water-repellent properties and is no longer dispersible in water.
Aerosil 300 Fumed Silica (SiO2): A white and colloidal micro-paricle with its primary micro-particle from 5-40 nm and has obvious properties such as thixotropy, reinforcing, thickening and filling etc, and is insoluble in all inkds of solvents and ilquids except hydrofluoric acid and concentrated bases.
