Levasil CT16 APL is an alkaline, aqueous dispersion of colloidal silica that is approximately 30% solids by weight. The silica dispersion is sodium stabilized and the amorphous silica particles carry a highly negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a semiwide particle size distribution. The particles have also been surface modified with aluminum. The physical appearance of the dispersion is an opalescent liquid, slightly more viscous than water. CAS number: 7631-86-9 Applications: Levasil CT16 APL is an optimized product with a proven performance within the coating and surface treatment area. Information provided by Nouryon |
