Glass beads

Glass beads can remove impurities and metallic oxides due to its hardness and ball shape, without damaging the treated surfaces themselves. Since glass does not react chemically with other minerals, the micro balls and concomitantly no foreign deposits do not cause any corrosion on the treated surfaces. Also available in a silane-treated quality.

Range of applications

Abrasive grinding | surface finishing | Wear resistance | UV-colours and lacquers | Road paint | Melamin resin applications |
