Levasil® CC503 is an alkaline, aqueous dispersion of colloidal silica that is approximately 50% solids by weight. The amorphous silica particles are surface modified and carry a negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a wide particle size distribution. The particles have been surface modified with silanes for optimized performance as emulsion stabilizer. The physical appearance of the dispersion is a white liquid, slightly more viscous than water. Levasil® CC503 is produced for world-wide distribution.
