GRITTAL GM is used in all applications where ferrous residue is a disadvantage or undesired.
GRITTAL GM has a lower hardness than GRITTAL GH, thereby resulting in its sharp angular edges rounding off in operation. However, the angular form of the grain is mostly retained.
GRITTAL GM is suitable for use in centrifugal wheel blast machines as well as air pressure systems and finds use in
cleaning, roughening, paint removal, deburring, and descaling, Primary application sectors are:
- Corrosion protection application (powder coating/paint)
- Rubber-metal bonding
- Simple descaling
If stubborn layers or stains must be removed when blast cleaning, GRITTAL GM can offer performance advantages when compared with CHRONITAL. GRITTAL GM is better able to break up and remove surface layers due to its higher hardness and angular grain shape. In addition, GRITTAL GM offers users the possibility to distinctly increase blasting performance given otherwise the same parameters.
