Sandblasting/Corn Cob

Corn Cob

Grit-O’ Cobs

A cleaner, safer, more versatile alternative to sandblasting.

Black Shot
Black shot is a new low free silica nickel slag abrasive. Black Shot nickel slag is a by-product left over from the operation of nickel smelters and is unsurpassed in it’s toughness, and durability. It’s angular shape and consistent sizing makes it particularly effective in attacking rust and paint leaving behind an excellent finish for coatings to adhere to, and done in less time than conventional sands.

Black Shot nickel slag is competitively priced in comparison to coal and copper slag abrasive materials. Customers will enjoy additional price advantages due to Canadian-dollar-denominated production costs.

Technical / Safety
• MDOT (Michigan Department of Transport) approved
• CARB (California Air Resources Board) approved
• Less than 0.1% free silica
• Modern screening technology provides even more consistent material.
• Now available with Blastox® lead abatement blast additive.

here is no need to mask windows when cleaning with Grit-O’Cobs. Loose and flaking paint can be quickly removed from painted wood, brick, masonry and metal structures.

Grit-O’Cob is also ideal for interior jobs since there is little dust – making it a preferred media for interior jobs.

Because of its biodegradability, Grit-O’Cobs is ideal for getting fiberglass, wooden and aluminum boats in ship-shape, as it can be acceptably used on beaches or in dry docks. Similarly – Grit-O’Cobs blast clean electrical substation insulators and electric motors.  Electircal substation insulators provide an ideal cleaning challenge for Grit-O’Cobs granules as it is biodegradable and non-toxic – there is no need for cleanup after blasting.


Applications and Application Equipment

Large-scale uses include the cleaning of buildings, bridges, boat hulls ( including fiberlglass ), mining equipment, earth-moving machinery and electric substations. Aircraft maintenance is another use of this versatile medium. Grit-O’Cobs is ideal for many types of metal finishing. Metal stampings, molded plastics, and die castings lend themselves to deburring, deflashing, burnishing and polishing in Grit-O’Cobs.

• When used on electric motors, Grit-O’Cobs removes moisture, grease, oil, carbon, copper dust, sand and grit
• Because corncob is “softer” than glass, window masking is not needed, and corncob will not “frost” glass, as will sand.
•  Grit-O’Cobs will not harm rubber parts.
