Modified Potassium colloidal silcia
It is a product developed to solve the weakness of sodium ions in collidal silica which will bring adverse effects on catalyst and other application industries. It is same as the modified sodium type,which has the advantages of compact, regular shape, smooth surface, clear shell, uniform size and so on,but it is suitable for all walks of life applications that do not like sodium ions.
