Heavy Industrial Blasting Abrasive

Engineered for maximum kinetic cutting efficiency, low dust generation, high recyclability, and non-hazardous operator safety across shipyards, petrochemical refineries, and structural steel fabricators.

GRADE: CS-ABRASIVE // ISO 11126-3 SYNTHETIC MINERAL SLAG

Copper Slag Blasting Abrasive (Iron Silicate)

Produced from granulated iron silicate generated during metallurgical copper extraction. The molten slag is rapidly water-quenched, producing vitreous, diamond-hard, faceted angular black particles with a bulk density of 1.70–1.90 g/cc and Mohs hardness of 7.0. Because it contains less than 0.1% free crystalline silica, it completely eliminates the dangerous silicosis health hazards associated with ordinary river sand, while achieving up to 3x faster cutting speeds and generating an ideal anchor profile for high-build marine epoxy coatings.

Core Product Features:
High Hardness: 6.5 – 7.0 Mohs
Free Crystalline Silica: < 0.1%
Conductivity < 25 mS/m (Chloride-Safe)
3x Faster Cleaning vs. Sand
Key Industrial Applications:
  • Marine Shipyards & Dry Docks: Ship hull blast cleaning, ballast tank relining, and marine antifouling recoating.
  • Oil, Gas & Offshore Platforms: Offshore drilling rigs, storage tank farm exteriors, subsea pipelines, and refinery steelwork.
  • Structural Steel & Infrastructure: Highway bridge descaling, pre-weld surface preparation, and heavy machinery repainting.
  • Concrete Etching: Exposing aggregate and profiling industrial concrete flooring before applying epoxy self-levelers.
