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 this product is water glass. Sodium meta silicate pentahydrate is generally immediately available in most volume. High purity, sub-micron and nano powder forms may be considered.
It is extensively used in the manufacturing of detergents, Silica Gel, card-board, paper, textiles, paints, pottery, adhesives, Sanitaryware, 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 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.
American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
