Sodium Metasilicate pentahydrate is formed by the high-temperature fusion of sodium carbonate and silicon dioxide. it forms highly alkaline solutions when dissolved in water. It is commonly used as a component of cleaners such as dishwasher detergent and laundry detergent.
The industrial name of this product is water glass. Sodium metasilicate pentahydrate is generally immediately available in most volume. High purity, submicron and nanopowder forms may be considered.
It is extensively used in the manufacturing of detergents, Silica Gel, cardboard, paper, textiles, paints, pottery, adhesives, Sanitary ware, Refractories, Foundry, and Wood Processing Industries because of it’s very good binding, adhesive, bleaching and sizing properties respectively. It is also used as electrolyte in keeping fine particles in suspension (of water) without allowing them to settle down.

Applications of Sodium metasilicate pentahydrate
A major use is as a builder (a material that enhances or maintains the cleaning efficiency of the surfactant, principally by inactivating water hardness) in soaps and detergents. Mainly used in making high-efficiency detergents and metal cleaners. As a substitute for STPP, it can increase cleaning efficiency and reduce environmental pollution, it provides excellent alkaline buffering, corrosion prevention for metal (i.e. Zinc, Aluminum), and aids in the of softening water. Used to improve washing detergents and metal cleaners.
It is also used extensively as an anti-corrosion agent in boiler-water feed.
Sodium metasilicate is used in fireproofing mixtures; in laundry, dairy, metal, and floor cleaning; in deinking paper; in washing carbonated drink bottles; in insecticides, fungicides, and antimicrobial compounds; as a chemical intermediate for silica gel catalysts; as an ingredient in adhesives; as a bleaching aid to stabilize hydrogen peroxide; as a clay deflocculant in the ceramics industry, and as a boiler compound. Combined with other salts such as sodium bicarbonate, it can be applied to aluminum as a paint stripper.
