Sodium silicate

Liquid, viscous, colorless, odorless, soluble, alkaline.

Viscous, clear liquid adhesive/binder with high pH. Soluble in water. Versatile use in pharmaceuticals, ceramics, detergents, and more. Sodium silicate is a widely utilized compound with diverse applications in various industries.

Energy Sector

Sodium silicate, a versatile compound, finds application in the energy sector as a key ingredient in drilling fluids for oil and gas exploration. It serves as a stabilizer and flocculant, preventing clay and shale from swelling and caving in during drilling operations. Additionally, sodium silicate is used in geothermal drilling for its ability to reduce water seepage, stabilize wellbores, and control fluid loss. Its unique properties make it an essential additive in the energy industry for improving drilling efficiency and ensuring wellbore stability in challenging drilling conditions.


Sodium silicate is used in construction as a concrete admixture, improving strength, durability, and chemical resistance. It acts as a binding agent, densifier, and sealer for concrete surfaces, protecting against moisture and chemical attack. It finds applications in grouts, mortars, and coatings for repair and rehabilitation of concrete structures, enhancing their performance and longevity.

Water Treatment

Sodium silicate is used in water treatment as a coagulant aid, flocculant, and pH stabilizer. It promotes coagulation and flocculation for effective removal of impurities from water. It also helps control pH, prevents corrosion and scaling, and is used as a binder in water treatment pellets. Sodium silicate finds applications in drinking water treatment, wastewater treatment, and industrial process water treatment.
