Glass Beads with the advantage of their hardness and spherical shapes easily cleans impurities and metal oxides without damaging the applied surface. Glass do not reacts with other materials so glass beads don't cause corrosion and prevents accumulation of impurities on the surface. Do not contains free silica or carcinogenic substances.
