Levasil® FX200 C is a cationic acidic, aqueous dispersion of colloidal silica that is approximately 31% solids by weight. The silica dispersion is chloride stabilized and the amorphous silica particles carry a positive surface charge. 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 with the recognizable smell of acetic acid. Levasil® FX200 C is produced for world-wide distribution.
