Due to its large specific surface area and strong adhesion, silica sol can be well fused with coating substrates and fillers, and with the evaporation of moisture in the silica sol, silica particles can form between them. A strong Si-OC bond gives it a strong film forming property. Because the organic matter of the oily coating is harmful, the water-based environmentally friendly coating does not contain an organic volatile solvent, and the silica sol is used as an aqueous solution of silica. The addition of the silica sol is a substrate in the aqueous coating, which can improve the hardness and reduction of the coating. Sex, and greatly improve the paint's resistance to water white, weathering, scrubbing, stain resistance and other properties. Silica sol has good penetration to concrete and cement mortar, and at the same time, the particles expand after penetration to firmly bond the paint to the wall.

SJ-alkaline, SZ-neutral series, HS-ammonia series and other coating-specific silica sol products, greatly improve the compatibility with various architectural emulsions and coatings, and can be universally applied to various water-based coatings, real stones. Paint, lotion, etc.

The Huihe S-small particle size series, due to the sharp increase in the number of gel particles and contact points in an equal amount of silica sol, increases the coating strength and coating properties, and can be applied to high-end coatings and special coatings.
