MineralTech-SL Application Chart

MineralTech-SL is a general purpose abrasive typically used when light to moderate coating removal is needed. The fine grain size and hardness will achieve a uniformed profile at great cleaning speeds, while remaining low in dusting during production. The sub angular grains allow for a cleaner more refined finish with less embedment, usually resulting in a near white to white blast finish. This product can be recycled and is used frequently in blast rooms, and blast cabinets.
