Colloidal Silica

Colloidal silica, is hydroxylated on the surface, is a stable suspension of spherical and ultrafine amorphous silica particles in a liquid. These particles generally range in size from 1 to 100 nanometers, which allows them to remain suspended in the liquid phase without sedimenting. The stability and uniformity of these particles give colloidal silica its unique and valuable properties.

It provides thermal stability to the final product with its high alkaline content, especially in precision casting applications, during temperature changes and preserves product viscosity.

Applications

• As a binding agent in the production of ceramic molds in which the casting is carried out in precision casting applications and in the production of ceramic and refractory,
• In the paper industry, as a coating agent to increase printability and reduce ink absorption,
• In the construction industry, as a strength-increasing additive in mortar, concrete and plastics and in the densification of concrete, cement and other materials,
• As a thickening agent in the formulation of paints and coatings and to increase the durability of the final product,
