Abrasive Garnet is intended for Private Blasting for both confined and open-air environments.
It is free of free silica, so it does not cause any harm to humans or the environment and has great physical properties. It may be an alternative to Sandblasting as it is prohibited by law.
It is also used in some medium grain size for waterjet cutting.
