COAL SLAG

Coal Slag is one of the most versatile abrasives available and is generally used for the removal of thick coatings, rust, and mill scale. Coal Slag is a widely used abrasive due to its profiling ability, economical price point, and availability. Coal Slag is frequently used in new steel and steel maintenance applications such as; blasting of storage tanks, water towers, bridges, ships, structural & plate steel, offshore platforms, and oil field maintenance.

• Bulk density: 80 – 90 lbs./cu. ft.
• Less than 1% free silica

COPPER SLAG

Copper Slag is an aggressive abrasive frequently used in new steel and steel maintenance applications. Copper Slag’s bulk density and angular shape give it an aggressiveness that provides clean, fast-cutting action, considerably increasing production rates. Copper Slag is ideal for abrasive blasting storage tanks, water towers, bridges, ships, structural & plate steel, offshore platforms, and oil field maintenance.

• Mohs hardness: 6.0
• Bulk density: 100 – 120 lbs./cu. ft.
• Less than 1% free silica

CORN COB

Corn Cob is an organic abrasive that will clean and polish without damaging the surface. Corn Cob is used as an alternative to other organic abrasives such as Walnut Shell when there are concerns with plant oils staining the substrate or affecting coating adhesion. Common applications for Corn Cob include refinishing log homes & cedar siding, cleaning of stainless steel food processing equipment, and specialty petrochemical & offshore applications where a non-sparking, non-ferrous abrasive is required.

• Angular to sub-angular
• Mohs hardness: 4.0
• Bulk density: 24 – 33 lbs./cu. ft.
• No free silica

CRUSHED GLASS

Crushed Glass is a manufactured abrasive made from 100% recycled glass, and is ideal for concrete applications and brick & limestone restoration work. Crushed Glass’ sub-angular shape provides a uniform mil profile and cleans by cutting through mill scale and rust while providing lower particle embedment than most other abrasives.

• Angular to sub-angular
• Mohs hardness: 6.0
• Bulk density: 80 lbs./cu. ft.
• No free silica

HARD ROCK, RIVER AND BEACH GARNET

The extremely low chloride levels of Hard Rock Garnet reduces surface contamination versus Alluvial River and Beach Garnets.  The sub-angular shape, hardness, and bulk density of Alluvial River Garnet provides fast cutting, ideal for removing thin to medium thickness coatings, mill scale, and rust. Aluvial River Garnet is not exposed to chloride contamination like Alluvial Beach Garnets. Alluvial Beach Garnet’s unique characteristics improve production rates, reduce abrasive usage, and lower disposal and clean-up costs. Typical applications include blast rooms, blast yards, bridges, offshore platforms, oil refineries, pipelines, railcar shops, shipyards, storage tanks, and water towers.

• Angular to sub-angular
• Mohs hardness: 7.0 – 8.0
• Bulk density: 130 – 150 lbs./cu. ft.
• Less than .5% free silica

GLASS BEADS

Glass Beads will clean metal parts without etching the surface. Glass Beads are commonly used for automotive restoration, polishing of castings, stainless steel fabrication, and light deburring of precision parts. Glass Beads are most commonly used in abrasive blast cabinets.

• Round
• Mohs hardness: 5.0 – 6.0
• Bulk density: 80 – 90 lbs./cu. ft.
• No free silica

PLASTIC MEDIA

Plastic Media is a soft, subangular abrasive widely used as an alternative to chemical or hand-stripping. It is commonly used in the removal of powder coatings, the cleaning of molds, automotive restoration, and the air-blasting of soft or thin metals, such as aircraft aluminum.
