Levasil CB25

Levasil colloidal silica

Levasil CB25 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 slightly rough, 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 CB25 is produced for world-wide distribution.
