Sodium Silicate 42% solution (Waterglass) is a clear, colourless liquid that is utilised in a number of applications such as water treatment, detergent manufacture, mining and construction, and foundry.

Sodium Silicate is used as coagulant/ de flocculant agent in wastewater treatment plants. It binds to colloidal molecules, creating larger aggregates that sink to the bottom of the water column. It also acts to inhibit corrosion of metal surfaces where industrial water is being stored.
