Description
Sodium metasilicate is used as a starting material for zeolites and silica catalysts. It acts as an adhesive and binder, corrosion inhibitor, penetrating sealant, coagulant in waste water treatment, fixative for hand dyeing with reactive dye and detergent auxiliaries. It is also used in boiler compounds, cleaners, bleaches, aluminum paint strippers and washing carbonated drinking bottles. It finds application in cements, drilling fluids, fireproofing wood, refractories and automobiles. Further, it serves as a surfactant, emulsifier, wetting agent, suspending agent, dispersing agent and anti-corrosive agent in boiler water.
