Levasil CC401 is a neutral, aqueous dispersion of colloidal silica that is approximately 37% solids by weight. The silica dispersion is sterically 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 particles have also been surface modified with an epoxy silane. “Hydroxyl number” for 2- pack systems; 0.45 mole OH/kg product.” The physical appearance of the dispersion is a translucent liquid, slightly more viscous than water. Levasil CC401 is produced for world-wide distribution. CAS number: 1239225-81-0 Applications: Levasil CC401 is an optimized product with a proven performance within the coating and surface treatment area. Information provided by Nouryon |
