Detergent and Cleaning Products: Sodium silicate is used in the manufacturing of laundry detergents and dishwashing detergents as a builder or anti-corrosion agent. It helps improve the cleaning efficiency of these products.

Paper and Pulp Industry: Sodium silicate is used as a binding and sizing agent for paper and cardboard production. It enhances the paper's strength and reduces the penetration of ink into the paper fibers.

Water Treatment: Sodium silicate is used in water treatment processes to coagulate and flocculate suspended particles and reduce water hardness.

Foundry and Metal Casting: Sodium silicate can be used as a binder in foundry sand molds. When mixed with sand, it creates a rigid, heat-resistant structure for casting metal.

Construction and Cement: In construction, sodium silicate is used in various applications, including as a concrete and cement admixture to enhance workability, durability, and fire resistance.

Adhesives and Sealants: Sodium silicate is used in the formulation of adhesives and sealants, particularly in applications where a durable and heat-resistant bond is required.

Fireproofing: It is used as a fire-resistant coating for wood and other materials due to its ability to harden and withstand high temperatures.

Textile and Fabrics: Sodium silicate is used as a flame retardant and finisher for fabrics and textiles.

Chemical Manufacturing: It serves as a raw material for the production of various chemicals, including precipitated silica, zeolites, and silica gel.

Egg Preservation: Sodium silicate is used to preserve eggs by sealing the pores of the eggshell, which extends their shelf life.
