Abrasive Sandblasting Glass Grit
Crushed glass abrasive grit is made from 100% recycled glass. This is an inert abrasive that substitutes for slag and mineral abrasives. It contains no heavy metals, no free silica, and is therefore great for sandblasting projects where it is impractical to recover lost or spilled, spent abrasive. Crushed glass offers significant cost savings over using plastic beads, soda blast, and glass beads. Because it's more aggressive, it's able to remove corrosion and tougher coatings that other medias cannot. Glass blasting grit is very economical, available in a variety of grit sizes.
Available in 25kg bags:
• Medium 1.5mm - Generally used for mill scale, rust, masonry, stone, concrete, also used in filtration and other industrial processes. Gives high cleaning rate and etch acceptable for most industrial coatings e.g. ship’s hulls, tank internals, pipe joints and general steel fabrications. NOT RECOMMENDED FOR USE WITH BLASTING EQUIPMENT WITH NOZZLE SIZE LESS THAN 4MM
• Fine .85mm - Fast and aggressive size for all finer blasting requiring a smooth, clean finish, excellent for powder coating, auto paint stripping.
• Super Fine .425mm - Is great for powder coating and auto restoration. For use on substrates where minimal etching and profiling is preferred, such as aluminium or fibreglass.
• Powder Fine .300 micron, very low profile - Substitute for soda blasting media. For very fine cleaning, brightening, de-burring, and fine honing with no damage to the substrate. Great for graffiti and soft metals as well as tile and brick.
Lead Time: Generally in stock and available to ship without delay.
Safety: MSDS available on request.
(It is recommend to use at 90 PSI for best results and increased energy savings, unless you are blasting aluminium or other soft surfaces.) ** The thinner the abrasive to air mixture, the higher your rate of production will be. Be stingy - meter the abrasive back until you can no longer see it in the air stream. This may sound counter-intuitive, but glass blasting is different from heavier abrasives.
Benefits of Glass Blast:
• Efficiently cleans steel, aluminium, wood, concrete, stone, fibreglass
• Glass Blast will leave a clean, bright finish to metal surfaces
• Excellent for achieving an aggressive profile for coatings, including cathodic protection and overlay performance
• Glass delivers very low particle embedment (less than 2%) which produces a whiter (SP-10) finish to the substrate.
• Lighter weight than most abrasives. Contractors report back that they use at least 25% less abrasive (some say up to 50% less) when using glass as compared to mineral slag.
• SAFE - no free silica, is chemically inert and non toxic.
• Inert - can use it around water
• Mohs Hardness of 6.0 - similar to slag.
• Superior rust-back performance when compared with mineral/slag abrasives.
• Contains no Beryllium like a mineral slag.
• Great for thick, softer coatings because it is a lighter weight abrasive. It does not "bounce" back off the surface. It cuts it like a knife.
• Great for concrete and leaves no residue, discoloration, no ferrous impingement, etc.
• Excellent replacement for soda blasting due to its lower cost and it will not leave a PH imbalance on the substrate (which often requires a PH wash solution so that the paint will adhere). Glass will also cut through rust and soda blast will not.
• Shall we say it again? It is a GREEN abrasive! 100% recycled glass.
We can also deliver up to 20 bags locally or to the north side of Brisbane for an extra $20.00.
