Sodium silicate (water glass) is a versatile alkaline silicate used as a detergent builder, corrosion inhibitor, adhesive, cement and water treatment chemical.
Inquire About This ProductSodium Silicate (water glass) is an inorganic silica-based compound available in liquid and solid (powder) forms with varying SiO₂:Na₂O ratios. It is an effective alkaline builder, sequestrant and anti-corrosion agent with excellent detergency-boosting properties.
Our technical grade sodium silicate is used primarily in detergent manufacturing as an alkaline builder and enzyme stabiliser. It also functions as a binder, adhesive and sealant in construction materials, and as a corrosion inhibitor and scale inhibitor in water treatment systems.
