Levasil CT16 PNL is an alkaline, aqueous dispersion of colloidal silica that is approximately 30% 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 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 ammonia. CAS number: 7631-86-9 Applications: Levasil CT16 PNL is an optimized product with a proven performance within the coating and surface treatment area. Information provided by Nouryon |
