METSO® sodium metasilicate and BRITESIL® hydrous polysilicate product families have been specially developed for modern detergents. From heavyduty industrial and institutional cleaning agents to consumer dishwasher and laundry detergents, METSO and BRITESIL enhance nearly every type of cleaning compound. In water treatment soluble sodium silicates serve to inhibit corrosion of various metals — iron, lead, copper, and zinc, among others and so reduce their concentrations in the treated water.
