Sodium silicate is an aqueous solution of sodium silicates (salts of silicic acid). It is widely used in the construction and building materials industry, including as an additive in concrete and mortar to strengthen surfaces and improve chemical resistance, for impregnating porous building materials such as concrete and brick, and in the manufacture of fireproof coatings. In addition, sodium water glass is used as an adhesive and stabilizer in paper and cardboard production, in the foundry industry, in corrosion protection, and in cleaning and washing agents.
Due to its strong alkalinity, fast reaction and curing properties, and comparatively low cost, sodium water glass is particularly suitable for industrial applications with high economic and technical requirements.
