                              • Ammonium Colloidal silica

                                This type use ammonium ion as stabilizer, compared with the colloidal silica use sodium ion as stabilizer, It has better toughness and air permeability, so it is more suitable for making fiber soft products in refractories, and electronic polishing, coating, flocking, wool spinning and other industries.
