Balotina
BALOTINA
Glass beads used in fine surface pretreatment, especially in blasting boxes. It is mainly used for blasting non-ferrous metals and stainless steel surfaces. It does not contain any free Fe which could cause corrosion on non-ferrous surfaces. It does not create an anchoring profile and is therefore also suitable for polishing surfaces.
Use
- Cleaning and polishing of aluminium and other non-ferrous metals
- Gentle surface blasting
- Final surface finishing
- Blasting of stainless steel surfaces
- Surface unification
