GTX Blasting Abrasives

The economy you want. Safety you can trust.

Barton introduces a new blasting abrasive offering exceptional economy, uniform surface finish and environmental safety compared to coal slag and silica sand abrasives.

Unique Mineral Blend.

Barton GTX is a unique, homogenous blend of natural minerals, including hornblende and feldspar. A hard, dense, low free-silica abrasive containing no heavy metals, GTX brings economy, safety and consistent performance to a wide range of blasting applications.

Environmentally Safe.

Mined and milled in the Adirondack Mountains of New York, Barton GTX contains less than 1% free-silica, and has no heavy metals, making it an economical, effective, and safe alternative to coal slag or silica sand when health and environmental safety are of concern.

Uniform Surface Finish.

Barton GTX is carefully graded and produces a consistent, uniformly clean, white metal surface finish without embedments, black residues and rogue peaks.
