Abrasives · Quartz-free
AYT Pro Blast Grit is a high-performance, non-silica mineral abrasive produced from processed metallurgical slag. It is engineered for abrasive blast cleaning of steel, concrete and industrial surfaces — efficiently removing rust, mill scale, old coatings and contaminants while creating an appropriate surface profile for coating adhesion.
The material contains no detectable crystalline quartz by XRD analysis, making it a safer, environmentally preferable alternative to traditional silica sand abrasives.
