Köstrosol® A 1530

1 of 11 products in this brand
Köstrosol® A 1530 is an opalescent aqueous dispersion of amorphous silicon dioxide nanoparticles. This middle-size colloidal silica has a negatively charged surface (anionic) which is stabilized by Alkaline (Na+) and coated by aluminum oxide. Köstrosol® A 1530 with the tested specification values receives an documented addition of sodium hypochlorite in order to obtain a residual chlorine content of between 1 - 3 mg/L (as Cl2) at the time of delivery.
