Copper Slag / Iron Silicate
Copper Slag also know as Iron Silicate is silica free, consumable abrasive blast media. It offers superior cutting and striping action leaving surface profiles ready to prime and paint. Ideal for large projects in shipyards, water tower blasting, pipe cleaning, and other heavy industrial paint striping applications.
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

Frequently Asked Questions (FAQs)
Q1. What is iron silicate abrasive?
Iron silicate abrasive, also known as copper slag, is a by-product of copper smelting. It is a tough, angular blasting media used for cleaning, surface preparation, and removal of rust, paint, and scale from metal and concrete surfaces.
Q2. What are the key uses of iron silicate abrasive?
- Surface preparation for coatings or painting
- Rust, scale, and old coating removal
- Cleaning ship hulls, steel structures, tanks, and pipelines
- Concrete surface cleaning and profiling
Q3. What are the advantages of using iron silicate over other abrasives?
- High density for faster cutting action
- Low dust generation
- Non-hazardous and environmentally safer than silica sand
- Angular shape provides an excellent surface profile
Q4. Is iron silicate abrasive environmentally safe?
Yes. It is a by-product material that is non-toxic, free from crystalline silica, and safe to use in most industrial and marine environments. Always follow local disposal regulations.
Q5. Is iron silicate reusable?
A: While iron silicate is more durable than sand, it is generally used in single-pass applications. It can be reused a limited number of times depending on the system and contamination level.
