Sodium Silcates – Water glass

Sodium silicate solution (Water glass) consist of oxides of silicon and sodium which are dissolved in water. The production of water glass is carried out by a hydrothermal process, and accordingly these solutions can be synthesized with a SiO₂/Na₂O ratio of 1.6 to 2.5 with an active component content of 38 to 44%. The solutions are colourless, with increased  viscosity and pH values.

These solutions were primarily developed as a raw material for the synthesis of various types of silicates and aluminosilicates, and are also used in the detergent industry, construction industry, cement production, foundry, production of refractory materials and paper industry. Water glass is used in metal, wood, textile processing processes. A significant application can also be in the treatment of waste water. Special formulations of sodium silicate solutions with the addition of additives have increased binding properties, which expands the area of
​​application to the production of adhesives.
