Components of Coated Abrasives

Components of Coated Abrasives

Covered abrasives are produced using free grating grains attached for support. The grounds that a covering of cement is applied to the support to moor a solitary layer of rough grain. Coated abrasives are accessible in sheets, rolls, plates, and belts and are utilized essentially for completing and light-to-medium granulating. 

The more significant part of the risks related to the utilization of coated abrasives can be followed by inappropriate mounting systems, backup cushion constraints, or over-the-top paces. Backup cushions might be firm or then again adaptable, elastic or plastic, smooth-looked for broadly helpful completing, rib-looked for air cooling, also have to hold nuts or speed-locking frameworks.

Components of Coated Abrasives 

“Natural gumming + Abrasive grains = Coated abrasive.”

Natural gluing and synthetic abrasive grains are coated abrasive main components. In which abrasive grains contain aluminum oxide, silicon carbide, zirconia alumina, garnet, and emery. While paper, fabric, fiber, and polyester film are common backing materials.

Let’s know each component of coated abrasive in details: 

Abrasive Grains

Coated abrasives are produced using synthetic abrasive grains. The primary abrasive grains are aluminum oxide, zirconium, ceramic, silicon carbide, and garnet. With the help of calibrated panels, the crude grains are crushed and sorted into grit sizes. 

Then these grains are bound to a backing material by applying several bonding methods. 

Most Popular Abrasive Grains

Popular Abrasive Grains

The most popular abrasive grains structure and uses are given below:


    Ceramic high-density grains are uniform and durable for longer life and sharp cutting. It is a synthetic abrasive material with high performance.

    Aluminum Oxide

      A rough structure synthetic grain used for high-speed grinding and finishing of metals, wood, and other high tensile strength materials without unnecessary fracturing or shedding.


        Zirconium gains are excellent, thick, crystalline & synthetic. Zirconium is a very dense material with a unique self-sharpening feature that gives it a long life in excessive stock removal.

        Silicon Carbide

          Silicon carbide a rough & sharp synthetic abrasive suitable for non-ferrous materials and non-metallic materials such as concrete, marble, and glass. Silicon carbide cuts faster than any other grain used in coated abrasives.


            Garnet is an almost sharp but weak bonding structure abrasive grain made of natural aluminum oxide. Its primary use in the wood industry is for the finishing of furniture as garnet dulls too quickly.

            Baking Material

            The backing material is used to stick the abrasive grains with the surface. It acts as a support for the coated abrasives. Backing material includes paper, cloth, fiber, etc.
