Airblast Glass Granules is an iron free angular abrasive made of high quality glass, which is used on surfaces like (stainless) steel, non- ferrous metals and woods. This environmental friendly abrasive is also often used in facade- and concrete cleaning.
The angular shape of glass granules has a more abrasive effect on the surface being blasted than glass beads, but it is not as aggressive as corundum due to the lower hardness.
