What Are Coated Abrasives?
2
COATED ABRASIVES
The coated-abrasive name derives from one layer
of abrasive grains being coated or deposited onto
a versatile or semi-rigid backing material using
an adhesive, like resin bond the grains to the
backing material. This text examines the coating
process, various sorts of grains, man-made
minerals, and backing materials for
coated-abrasive products for several metalworking
applications.

COMPONENTS OF COATED ABRASIVES
ABRASIVE GRAINS
Coated abrasives are developed using abrasive
grains. The foremost common abrasive grains are
alumina, zirconium, ceramic, carbide, and garnet.
CERAMIC
It is a high performance, man-made abrasive,
which is a very uniform, high-density grain
structure. Ceramic is extremely durable and
self-sharpening for extended life and a more
relaxed cut.
4
ALUMINUM OXIDE
It is a challenging, blocky shaped, man-made
grain used for top speed grinding and finishing
metals, wood, and other high-lasting materials
without excessive fracturing or shedding.
ZIRCONIUM
Zirconium may be a very thick material with a
singular self-sharpening characteristic, which
provides its long life on massive stock removal
operations.
5
SILICON CARBIDE
It is a rigid, very sharp, man-made abrasive
fitted to non-ferrous materials and non-metallic
materials like concrete, marble, and glass.
GARNET
Garnet is formed of natural alumina, which may be
a relatively strong but fragile bonding
structure. Very inconsistent in comparison to
synthetics.
