ABRASIVE GRAINS

Chemours Starblast^® Products

Staurolite® is a name for a variety of loose mineral abrasive grains that the Chemours Co. domestically manufactures. These Staurolite Products are used for various applications, the most popular of course being surface preparation for a coating on steel. There are approximately 5-6 products that are available in the Chemours Staurolite Products group.

The most widely used abrasive grain is Starblast® which provides a 1.8-2.2 mil profile on either new or lightly coated or rusty steel. Starblast is very popular with painting contractors because of the product’s low dust and fast cutting qualities. Starblast is also 95% free of silica.

The coarsest product in the Staurolite Products group is appropriately called Coarse Staurolite®. Coarse Staurolite is the most aggressive product in the Staurolite Products group.

Starblast® Ultra, a fairly new product from duPont, is a mixture of Starblast and Coarse Staurolite. Starblast Ultra is an aggressive, extremely efficient and more readily available abrasive grain.

Yet another product from duPont, Starblast®XL, contains less than 1% free silica and it is approved for dry-blasting at U.S. Naval shipyards.

Finally, Biasill®, the finest abrasive grain in the Staurolite Products group, is excellent where low mil profiles are needed and has also been used in wet-blasting applications on surfaces such as brick and aluminum.
