Adding Colloidal Silica into your silicate paint formulation allows you to improve durability, weather resistance, coloring and anti-soiling properties as a binder. Potassium silicate in combination with colloidal silica is the main binder in sol silicate paint, industrial & decorative coatings as well as elastomeric cool roof coatings. Formulating with colloidal silicas helps minimize internal stress, enhance abrasion resistance, improve film properties and adhesion, otherwise a potential problem in inorganic coatings. The anti-soiling properties of the sol-silicate paints are a result of colloidal silica making it very hard for dirt to adhere to the painted stone or masonry. All this gives your inorganic coatings qualities that secure longer lasting protection and color, decorative paint, and silicate paints. We offer COLLOIDAL-SIL™ in a variety of grades ranging in nano-particle size, solids, pH and biocide-free or low biocide solutions. Grades: (NS6)15% , (NS6)15% (NS7)15%, (NS7)15% C, (NS8)20%, (NS8)20%, (NS20)40%, (NS20)40%
