Levasil® CT17 PDL is an acidic, aqueous dispersion of colloidal silica that is approximately 30% solids by weight. The silica dispersion is stabilized by absence of electrolytes and the amorphous silica particles carry a non charged surface. 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 an opalescent liquid, slightly more viscous than water. Levasil® CT17 PDL is available for world-wide distribution.
