Köstrosol® 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+). Köstrosol® 1530 is a pure colloidal silica without any organic additives.

Köstrosol® 730 is a weak opalescent aqueous dispersion of amorphous silicon dioxide nanoparticles. This small-size colloidal silica has a negatively charged surface (anionic) which is stabilized by Alkaline (Na+). Köstrosol® 0730 is a pure colloidal silica without any organic additives.

Köstrosol® AD 1530 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 weakly acidic ion exchange.

Köstrosol® AD 2035 is a whitish turbid 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 weakly acidic ion exchange.
