Levasil CX4 is an alkaline non-aluminate modified, aqueous dispersion of colloidal silica that is approximately 50% 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 narrow particle size distribution. The physical appearance of the dispersion is a white product, slightly more viscous than water. Levasil CX4 is produced for word-wide distribution CAS number: 7631-86-9 Applications: Levasil CX4 is a specialty large particle product used for the interlayer formation of fire resistant glass elements.
