Advantages Over Other Abrasives
GMA Garnet abrasive is composed of natural Almandite
garnet grains that are known for their natural
hardness, durability and abrasive characteristics.
It is a cost–effective alternative to silica sand, mineral
slags and steel grits as the perfect symbiosis of grain size,
density and hardness/durability creates the optimum
abrasive efficiency-lowest abrasive consumption (lbs./ft2) at
the highest production rates (ft2/hr.).
Blasting cleaning using GMA Garnet provides significantly
lower dust emissions due to its inherent material tough-
ness and rapid setting (high specific gravity). is ensures
minimum disruption and danger to adjoining operations and
improves operator visibility and safety.
Very fast cutting is achieved with speed, large number and
shape of grains impacting on the surface. e acceleration
and speed of a grain in an air stream is a function of the
inertia and hence the size of the grain. Smaller grains accel-
erate much more readily and impart higher impact energy to
surfaces resulting in a superior cleaning rate-usually twice
the ft2/hr. of conventional abrasives.
T he unique grain size enables many more active
grains impacting the surface and greatly reduces
Superior Surface Quality
GMA Garnet grains clean deep into the cavities and pitted
areas down to the bare metal, thoroughly removing all rust,
soluble salts and other contaminations. e blasted surface is
free of embedment and rogue peaks and troughs. SA3 W hite
Metal is effortlessly achieved. Surface profiles ranging from
1 to 4.5 mils (determined by the mesh size utilized) are also
easily achieved along with a much greater number of peaks
per unit area.
Improved Health & Safety
and the Environment
GMA Garnet is non-toxic with no silicosis hazard or risk of
contamination from leachable heav y metals or radioactive
substances. Disposal volumes are greatly reduced as a result
of lower consumption and recyclability.
GMA Garnet is suitable for multiple usages and can be recycled
5 times or more without losing its superior cutting ability.
Special garnet recycling systems are available upon request.
ese add up to natural clean and cost effective blasting.
Being environmentally inert, GMA Garnet meets all
Occupational Health and Safety requirements and achieves the
highest quality of processing standards in respect of mineral
purity and the stringent requirements of ISO 11126-10
SSPC AB-1, QPL mil spec 22262-b, and have all sizes
California C ARB approved.
