Levasil FX300 is an alkaline, aqueous dispersion of colloidal silica that is approximately 30% solids by weight. The silica dispersion is sodium 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 semi-wide particle size distribution. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water. CAS number: 7631-86-9 Applications: Levasil FX300 is an excellent binder for very high concentrated slurries of inorganic materials as refractories. Information provided by Nouryon |
