Nouryon-諾力昂 Levasil GB3000 Colloidal silica水性納米二氧化矽分散液

2021-03-07 10:30

Levasil GB3000 is an alkaline, aqueous dispersion of colloidal silica that is approximately 15% solids by weight. The silica dispersion is sodium stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are structured to enhance the activity of the dispersion. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water. Levasil GB3000 is produced primarily for the Asian and European markets.
