Levasil CT13 PNM 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 smooth, spherical shape, and are present in a narrow particle size distribution. The physical appearance of the dispersion is an opalescent liquid, slightly more viscous than water with the recognizable smell of ammonia. Levasil CT13 PNM is produced for world-wide distribution. CAS number: 7631-86-9 Applications: Levasil CT13 PNM is an optimized product with a proven performance within the coating and surface treatment area. Information provided by Nouryon |
