Nouryon Levasil CA316 PNL Colloidal silica
Categories: Other Engineering Material

Material Notes: 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.
