| Levasil FO2040 is an alkaline, aqueous dispersion of colloidal silica that is approximately 40% 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 slightly rough, spherical shape, and are present in a narrow particle size distribution. The physical appearance of the dispersion is an opalescent liquid, slightly more viscous than water. Levasil FO2040 is produced for world-wide distribution. CAS number: 7631-86-9 Applications: Levasil FO2040 is an excellent binder with very high binding power for a broad variety of inorganic materials as refractories. Information provided by Nouryon |
