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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
