Nouryon 諾力昂 Levasil GB1000 Colloidal silica水性(xìng)納米二氧化矽分(fen)散液

　　Levasil GB1000 is an alkaline, aqueous dispersion of colloidal silica that is approximately 30% solids by weight. The product is sodium stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a slightly rough, spherical shape, and are present in a narrow particle size distribution. The physical appearance of the dispersion is a translucent liquid, slightly more viscous than water. Levasil GB1000 is produced for world-wide distribution.
