STAUROLITE®/STARBLAST® BLASTING ABRASIVES

We offer the full range of DuPont™ Staurolite® and Starblast® blasting abrasives that can be used in a wide variety of applications. Most notably, to remove shell material from parts and molds along with the removal of paint, rust, mill scale and weathered coatings. These quality materials are also used in etching marble and granite.

These materials are separated and washed at the mine site to give a high uniform grade while reducing dirt, dust and ultrafines.
Advantages of Staurolite® and Starblast® include:

• Reduction of dust generation which increases visability of blasting surface

• A cleaner, faster, more efficient cleaning which lowers labor costs

• Rounded to subangular grains result in less abrasive embedment

• Electrically nonconductive

In using these blasting abrasives it is always important to use appropriate PPE (personal protective equipment) in a sufficiently ventilated work area. Please click here to view an MSDS for complete safety information.
