Copper Slag / Iron Silicate Copper Slag / Iron Silicate is ideal when a quick and efficient paint-stripping process is required. It produces a heavy to medium etch depending on the grade and leaves the surface to be primed and painted. This is a high-performance material trusted for heavy-duty blasting jobs across industries where you need to strip paint, rust, or scale fast. Copper Slag is a consumable, silica-free premium alternative to silica sand. Used in everything from bridges to barges, iron silicate abrasive blasting delivers a deep etch and clean finish that’s ready for coatings. It has minimal dust and is strong enough to take on stubborn surface contaminants with ease. Benefits Silica Free (less than 0.1%) Fast and efficient surface cleaning Very low dust Meets SSPC-AB1 and MIL-A-22262B (SH) Clean Surface Finish Surface profile from 2.0 to 5.0 Efficient Blasting and Less Grit Used Applications Rust, paint, and scale removal Bridge stripping and maintenance Barge and ship blasting Military vehicle and boat stripping Water tower stripping Surface preparation on new metal High-pressure water blast systems Whether you call it copper slag or iron silicate abrasive, this media is all about performance without compromise. It cuts through buildup fast, leaves a clean profile, and doesn’t flood your workspace with dust. And because it’s a consumable abrasive, it’s ideal for one-time or high-turnover blasting projects.
