PATRIOT BLAST

Coal slag is an inert material and environmentally safe. ERI coal slag products do not exhibit any hazardous waste characteristics and pass all tests concerning heavy metals analysis, TCLP testing, SSPC AB-1, and is approved by the United States Navy for blasting at our nation’s major warship and submarine bases. Because Coal Slag is vitrified, the chemical attributes within the amorphous glass-like structure are encapsulated even when the granules are shattered at high speeds during blasting.  Because Coal slag products are recycled, their production don’t impact our environment like mined sources of competing products like garnet or sand.  Coal Slag products are Low- Free Silica in nature and are THE safer alternative to silica sand and other crystalline silica-rich materials.  Learn more about Coal Slag abrasives in the Learning Center.
