Köstrosol® WA 1520 is an opalescent aqueous dispersion of amorphous silicon dioxide nanoparticles. This middle-size colloidal silica is pre-final coated and stabilized by aluminum oxide. Afterward, the PH is adjusted by a strongly acidic ion exchange. Köstrosol® WA 1520 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.
