Our Garnet is mined from mineral deposit sources on the coastal stretch
of South India. Garnet is a semi-precious stone whose natural properties make
it the most efficient abrasive for many industrial applications. Almandine
Garnet grains are the most versatile natural blasting & cutting medium
available in the international market today. Its inherent physical and chemical
uniformity ensures better performance and its repeatability, low dust levels,
high specific gravity, cutting accuracy makes it ideally suitable for the
blasting industry.
The end uses of industrial garnet are as abrasive sand blasting media, water jet
abrasives, abrasive grains, filtration media, precision abrasive powder and
other miscellaneous abrasive uses. Garnet abrasive grains support a full line
of bonded and coated abrasive products for surface conditioning of metals, wood
and most synthetic surfaces.
Some of its applications are:
12 ~24 Mesh: One of the most preferred products for
multi-media-water-filtration systems. It can also be used for specialized
application where excessive surface profiling is required or very high built
coating systems are to be removed. 20~40 Mesh: It
is an abrasive that can be utilized for heavy-duty coating removal.
20~60: It is the most cost effective and excellent
abrasive, suitable for fast and efficient removal of existing coatings. It is
perfect for all types of blasting applications including, removing existing
coating, rust and other contaminations. It is an ideal choice for superior
surface preparation for pipelines, fabricated steel and structures.
80 Mesh: It possesses highest grain count per weight/volume which
makes it an ideal choice for surface preparation of Aluminum and non-ferrous
surfaces.
120 Mesh: Utilized for surface preparation of
stainless steel and Aluminum where minimum surface roughness is desired. It can
be used on synthetic products too.

| Copper Slag |
|
Copper slag is a fast
cutting, high quality, yet economical choice for shipyards and contractors.
More than 20 years of history stand behind this type of abrasive grain. , our
copper slag was shown to be the best abrasive not only in cutting speed, but
also in cost per sq. ft.
It is also environmentally friendly, approved to be recycled into the
manufacture of Portland cement.
Advantages of Copper Slag:
• Cubical
• Dense
• Fast Cutting
• Leaves a good profile
• Inert
• Produces less dust
• Contains less than 0.1% crystalline silica
• Coverage: typically gets twice the coverage of silica.
• Uses: Used to remove rust, scale, paint from steel items. These slag are
often used by power plants, tank companies, water districts, and waste water
transfer plants as blasting abrasives

| Aluminum Oxide |
|
 |
|
Aluminum oxide is an
extremely sharp, long-lasting blasting abrasive that can be recycled many
times. It is the most widely used abrasive in blast finishing and surface
preparation because of its cost, longevity and hardness. Harder than other
commonly used blasting materials, aluminum oxide grains penetrate and cut even
the hardest metals and sintered carbide
Approximately 50% lighter than metallic media, aluminum oxide has twice as many
particles per pound. The fast cutting action minimizes damage to thin materials
by eliminating surface stresses caused by heavier, slower cutting media.
Aluminum oxide has a wide variety of applications, from CLEANING ENGINE HEADS
,VALVES,PISTONS , TRBINE BLADES and FOR ITCHING GLASS & STONE and marker
inscriptions. It is also commonly used for matte finishing, as well as cleaning
and preparing parts for metallizing, plating and welding. Aluminum Oxide is the
best choice for preparing a surface for painting.
We recommends using, brown aluminum oxide for optimal performance versus
reprocessed product, brown aluminum oxide contains less than 1.5% free silica
and is therefore safer to use than sand. The grit size is consistent and cuts
much faster than sand, leaving a smoother surface.
The larger the grit size, the faster it will cut, but consider the size of
perforations or holes through which the grit must pass when screen separating
parts from media after use.
Aluminum Oxide is also used as a durable and efficient non-skid media. The
angular shape of Aluminum Oxide makes it an ideal grit for use in a variety of
non-skid applications including concrete floors, stairs and boat decks. The
inert
nature of Aluminum Oxide allows it to be used with a variety of coating
materials. The hardness of the grit particle creates a durable, long-lasting
surface that requires minimal maintenance
Advantages
# The high percentage of TiO2 (2.8%) shows the toughness of the product and
results in longer cutting life, more circulations before breaking
down and increased cost-effectiveness.
# Outstanding physical properties result in faster cutting and surface
smoothing; shorter work cycles and increased production.
# No detectable "crystalline silica

| Glass Beads
|
|
 |
|
| Glass beads are manufactured
from lead-free, soda lime-type glass, containing no free silica that is made
into preformed ball shapes. Glass beads produce a much smoother and brighter
finish than angular abrasives. Glass beads can be recycled approximately 30
times. Chemically inert and environmentally friendly, glass beads are an
acceptable method of metal cleaning or surface finishing when properly
controlled.
Glass beads produce a clean, bright, satin finish, without dimensional change of
the parts. Available in a wide range of sizes, glass beads are primarily used
in blasting cabinets for honing, polishing, peening, blending, finishing,
removing light burrs and cleaning most light foreign matter. For delicate
thin-walled parts and thin welds, peening with glass beads provides the right
balance of stress relief without over-stressing and causing damage. Consider
the size of perforations or holes through which the glass beads must pass when
screen separating parts from media after use.
Produced from soda-lime, glass beads are used for peening and the removal of
almost any surface blemish. They can be used safely for texturing or producing
attractive cosmetic finishes, without damaging the base material. Being totally
inert, there is no risk of corrosion or any contamination whatsoever. Unless
excessive blasting occurs, there is no alteration in the dimensions of the
treated surfaces. Strict control of both manufacturing and grading processes
ensures consistency of finish

| Hydromix Hard
|
|
| Hydromix hard is a mixture
Developed as an alternative to the more expensive abrasives ,hydromix hard is
more aggressive and is excellent for removing and cleaning of heavy oils off of
tank insulation and equipment. This product will also leave a profile on some
materials such as fiberglass, plastic, aluminum, glass or other soft substrates
Choosing A Blast Media
|
|
 |
|
| Hydromix Soft |
|
no toxic fumes or chemical
solvents required
- absorbs odours and has a benign ph of 8.2
- the media is relatively soft at 2.5 mohs hardness
- no sparking, non flammable, non hazardous, water soluble
- gentle yet effective cleaning with a minimum of disturbance to the substrate
- will not etch glass
- will not damage bearings or seals (product is friable – breaks on contact)
- food grade approved
- generally more aggressive and less costly than dry ice |

| Steel Shots & Grits
|
|
We produces high quality
cast steel shot and grit used for a wide range of applications , from sand
removal for foundry products to shot penning in aeronautics industry.
Steel abrasive comes in round (shot) or angular (grit) form, ranging from 0.004
to 0.03 in. in size. It is produced by the atomization of molten steel,
followed by a series of thermal and mechanical treatments in order to give the
product is final characteristics.
Steel grit tends to clean a little quicker than shot but breaks down at a
faster rate. It is essential that media is kept in a moisture free environment,
otherwise it may solidify. Due to the risk of ferrous oxide contamination,
steel shot or grits are not suited to certain applications. Surface corrosion
may occur after treatment, therefore immediate coating or temporary protection
is essential. Metallic abrasives are available in three different types;
suitability depends on application.
Steel shot is made from high carbon steel which is tempered to give durability
and resistance to fracture, used both for peening and cleaning. Typical
applications include metal improvement, stress relief, removal of heat
treatment residue, mill scale, rust and paint and sand from castings.
Chilled iron grit is a white iron structure which shatters on impact rather
than wearing round. Being harder than steel it has a quicker cleaning action.
If used in automatic machines it can be less cost effective than steel due to
its breakdown rate. |
