Colloidal silica is an essential component in the making of sol silicate paint. Colloidal silica is used in combination with potassium silicate as the main binder in manufacturing sol silicate paint. The chemical is also available in low biocide or biocide-free solutions. Colloidal silica helps improve the weather resistance of paint, lower solubility and pH of the binder, and reduce alkalinity. Additionally, it helps improve film properties and adhesion and minimize internal stress, a significant problem in inorganic coatings.
