Inorganic polymer building coating is a new type of architectural coating developed in recent years. Widely used in buildings are alkali silicate and silica sol two.
Organic polymer building coatings are generally resistant to aging, poor performance, poor heat resistance, and small surface hardness. Just paint inorganic molecules in these aspects of good performance, aging resistance, high temperature resistance, corrosion resistance, durability and good performance, film hardness and good abrasion resistance, if the material is reasonable, good water resistance, and wide source of raw materials, the price is cheap, so in recent years attracted widespread attention at home and abroad, the rapid development of. Here is a description of silica sol coatings. Silica sol exterior paint with colloidal silica (silica sol) as main film-forming material, organic polymer emulsion film-forming material for auxiliary, pigments, fillers and additives, stirring, grinding, modulation and water dispersion paint, coatings is excellent performance in recent years the development of new good,
Main performance characteristics: (1) water as a dispersing medium, non-toxic, odorless, no pollution of the environment. (2) the construction performance is good, suitable for brushing, spraying, roll coating and coating, and the tools can be cleaned with water. (3) the coating has strong penetration to the base and good adhesion. (4) the covering power is strong, and the brushing area is large. (5) the coating is fine, the color is even and bright, and the decoration effect is good. The film is compact, hard and abrasion resistant. It can be polished and polished with water sanding paper. (6) the film does not produce static electricity, it is difficult to absorb dust, and it has good pollution resistance. (7) film with silica sol as the main film-forming material, with acid, alkali, boiling water resistance, high temperature resistance and other properties, and not easy to aging, good durability. (8) raw materials are rich in resources and low in price.
