What is Sodium Meta Silicate?
Sodium Meta Silicate (Na₂SiO₃) is an inorganic compound commonly known as water glass or soluble glass in its liquid form. It is available as a white granular powder (anhydrous or pentahydrate) and is highly alkaline with excellent cleaning, binding, and sealing properties. It is one of the most widely used industrial silicates globally.
Polychem Industries supplies Sodium Meta Silicate in industrial grade, available in both anhydrous and pentahydrate forms. It is a key raw material in detergent manufacturing, industrial cleaning products, construction chemicals, and surface treatment applications. Its strong alkalinity and emulsifying properties make it indispensable in heavy-duty cleaning and industrial processes.
Available Grades
| Grade | Form | Purity | Standard | Applications |
|---|---|---|---|---|
| Anhydrous Grade | White Granular Powder | 95%+ | Industrial | Detergents, heavy-duty cleaners, construction |
| Pentahydrate Grade | White Crystalline Powder | 95%+ | Industrial | Dishwasher detergents, industrial cleaning, surface treatment |
Applications & Uses
Detergent Manufacturing
A key builder and alkalinity source in powder detergents, automatic dishwashing compounds, and industrial cleaning formulations. It boosts cleaning performance and prevents soil redeposition.
Industrial Cleaning
Used in heavy-duty industrial cleaners for degreasing metal parts, cleaning machinery, and removing grease, oil, and protein-based soils from industrial surfaces.
Construction & Waterproofing
Used as a waterproofing agent for concrete and masonry surfaces, as a soil stabiliser, and as a component in fire-resistant coatings and construction boards.
Metal Surface Treatment
Used in metal cleaning, pickling, and surface preparation processes before painting or coating. It removes oxides and prepares surfaces for adhesion.
Ceramics & Refractories
Used as a binder in the manufacture of ceramics, foundry moulds, and refractory materials. It provides excellent bonding strength at elevated temperatures.
Paper & Pulp Industry
Used as a bleaching auxiliary and hydrogen peroxide stabiliser in the paper and pulp industry, improving whiteness and preventing metal-catalysed peroxide decomposition.
