Nalco Water supports the Refractory industry with colloidal silicas designed to improve the thermal and mechanical performance of a range of refractory products, from light weight, vacuum-formed shapes to denser castable refractories. Our colloidal silicas offer consistent flocculation properties as well as high strength for rigidizing and inorganic applications. In addition to these offerings, we have a selection of low sodium colloidal silicas to meet the needs of extreme high temperature applications.
