Levasil® OF50 P is an alkaline, aqueous dispersion of colloidal silica that is approximately 15% solids by weight. The silica dispersion is sodium stabilized, biocide free 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® OF50 P is produced for world-wide distribution.
