Sodium Meta Silicate

Shreenath marketing produce different grades of Sodium Metasilicate suitable for many industries. Mainly we produce SODIUM METASILICATE PENTAHYDRATE ( 5H2O), SODIUM METASILICATE NONAHYDRATE (9 H2O).

Sodium Metasilicate is formed by the high temperature fusion of sodium carbonate and silicon dioxide. Sodium Metasilicate 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 it is water glass. It is extensively used in the manufacturing of Detergents, Silica Gel, Card-board, Paper, Textiles, Paints, Adhesives, Pottery, Sanitaryware, Refractories, Foundry and Wood Processing Industries because of its 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. It is considered to be safer to use than sodium hydroxide (caustic soda) and does not attack metals including aluminium as aggressively as caustic. It moderates the tendency of the alkali to corrode and dissolve metals. Sodium silicate reacts with metal oxides to form a protective film on metal surfaces. This film is maintained as long as small amounts of soluble silica remain in the presence of water. When used in conjunction with surfactants / detergents sodium metasilicate aids 1. The neutralization of acidic soil 2. The emulsification of oily and greasy soil 3. The deflocculation of particulate soil 4. The suspension of removed soil and prevention of it’s redeposition. Sodium metasilicate disperses grease and dirt deposits into small suspended particles that rinse away without redepositing on freshly washed surfaces


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 environment 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 stabilise hydrogen peroxide; as a clay deflocculant in the cermics industry, and as a boiler compound. Combined with other salts such as sodium bicarbonate, it can be applied to aluminum as a paint stripper. Sodium Metasilicate use in metal treatment chemical industries, ceramic industries, powder & liquid detergent industries, cleaning powder in metal industries, Speciality chemicals industries.
