Product Features

The acidic silica sol is a colloidal solution of amorphous silica particles of varying sizes in water having a pH in the range of 2 to 4. It has large specific surface area and adsorption, good adhesion and good high temperature resistance, water resistance and slip resistance.

In the acidic system, the pH is better in the range of 2 to 4, and in the range of 4 to 7, the gelation process of the silica sol is intensified.

Product application field

Product application: Acidic silica sol is mainly used in textile, coating, non-stick coating and other industries.
