Levasil CA421 PNH
Product Line Levasil colloidal silica
Levasil® CA421 PNH is an alkaline, aqueous dispersion of colloidal silica that is approximately 40% solids by weight. The silica dispersion is ammonia stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a slightly uneven, 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 with the recognizable smell of ammonia. Levasil® CA421 PNH is produced for world-wide distribution.
