Nouryon-諾力昂 Levasil GB5000 Colloidal silica水(shui)性納米二氧(yǎng)化矽分散液(yè)

Levasil GB5000 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 negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a semi-wide particle size distribution. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water. Levasil GB5000 is produced for worldwide distribution.
