Adding Levasil® colloidal silica into your silicate paint formulation allows you to improve durability, weather resistance and anti-soiling properties
Potassium silicate in combination with colloidal silica is the main binder in sol silicate paint. With Levasil® products we offer biocide-free or low biocide solutions. Colloidal silica reduces alkalinity, lowering the pH and solubility of the binder, hence improving the weather resistance of the paint. Furthermore, it helps minimize internal stress, 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.
