Levasil CB50 is an alkaline, aqueous dispersion of colloidal silica that is approximately 15% solids by weight. The silica dispersion is sodium stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are structured to enhance the activity of the dispersion. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water. Levasil CB50 is produced for world-wide distribution. CAS number: 7631-86-9 Applications: Levasil CB50 is a specialty product used primarily in concrete to control stability, segregation and water loss. Information provided by Nouryon |
