nouryon 諾力(lì)昂 levasil cb301 colloidal silica水性(xìng)納(nà)米二氧化(huà)矽分(fèn)散液

levasil cb301 is a neutral, aqueous dispersion of colloidal silica that is approximately 28% solids by weight. the silica dispersion is sterically 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 particles have also been surface modified with an epoxy silane. the physical appearance of the dispersion is a clear liquid, slightly more viscous than water. levasil cb301 is produced for world-wide distribution.
