nouryon-諾力(lì)昂(áng) levasil gb5000 colloidal silica水性納(nà)米二(èr)氧化(huà)矽分散液

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.
