ABSHOT/H is an additive for cleaning metallic blasting media and for the improvement of blast results in blasting systems. Contamination due to grease, oils, etc from the production process is effectively and tgoroughly removed from blasting media, the blasting system and blasting material during basting. The cleaned blasting media can then accomplish its tasks more effectively, more regularly and more consistenle, e.g. material abrasion or cold work hardening. By adding ABSHOT/H the the blasting media additive, metal surfaces can be blasted practically without the usual pre-cleaning (washing) and be directly coated with suitable coating systems even without cleaning afterwards.
