Levasil CA316 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 CA316 PNL is a specialty product primarily used for the catalyst market. Information provided by Nouryon |
