Levasil PA45 is an alkaline, aqueous dispersion of colloidal silica that is approximately 45% solids by weight. The silica dispersion is sodium 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 wide particle size distribution. The physical appearance of the dispersion is a white liquid, slightly more viscous than water. Levasil PA45 is produced primarily for the European market. CAS number: 7631-86-9 Applications: Levasil PA45 is a specialty product designed primarily for use as an anti-skid and a frictionizer. The product is modified with an organic additive to reduce its adhesion to metals as well as to provide freeze stabilization. Information provided by Nouryon |
