Levasil FX401

Product Line Levasil colloidal silica

Levasil® FX401 is aqueous dispersion of modified colloidal silica. The silica dispersion is sterically stabilized, and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a narrow particle size distribution. The physical appearance of the dispersion is a translucent liquid, slightly more viscous than water. Levasil® FX401 is produced for world-wide distribution.

  • Applications

    Levasil® FX401 is a unique colloidal silica binder targeted for refractory systems containing MgO. It presents good workability in basic systems as well as prevents the MgO from hydroxylation. Additionally, at high temperatures, this innovative colloidal silica also helps the generation of high refractoriness phases, contributing to high performance refractories.
