Levasil CB301 is a neutral, aqueous dispersion of colloidal silica that is approximately 28% solids by weight. The silica dispersion is sterically stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a narrow particle size distribution. The particles have also been surface modified with an epoxy silane. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water. Levasil CB301 is produced for world-wide distribution.
