Types of Coated Abrasives

The coated abrasives produced by our company mainly include the following types:

Abrasive Belt

Our abrasive belt is made of good quality abrasive cloth on the P type of FEPA standard including the brown aluminum oxide, black silicon carbide, zirconia and ceramic abrasive grains. The advanced manufacturing techniques guarantee consistent quality, making each abrasive belt a good stable quality product.

Black SiC Waterproof Abrasive Paper

Our silicon carbide waterproof sandpaper offers excellent quality performance. The silicon carbide abrasive grains have high hardness, which enables efficient polishing and grinding. They can maintain their sharpness during the grinding process, ensuring a stable material removal rate.

Applications of Coated Abrasives

Metalworking

Industries like automotive, aerospace, and general manufacturing rely heavily on coated abrasives for grinding, polishing, and finishing metals. Aluminum oxide, zirconia alumina, and silicon carbide are commonly used for metalworking tasks, especially for tougher metals.

Woodworking

Coated abrasives are essential for woodworking, particularly in sanding tasks. Aluminum oxide and garnet abrasives are commonly used for sanding wood, furniture, and cabinetry to achieve smooth finishes.

Automotive and Aerospace

Heavy-duty grinding and finishing tasks in the automotive and aerospace industries often use ceramic alumina and zirconia alumina abrasives, ideal for grinding high-strength metals and alloys.

Glass and Ceramics

Silicon carbide is perfect for grinding and polishing glass and ceramics. Its sharpness and ability to withstand high temperatures make it an excellent choice for these fragile yet tough materials.

The Different Colours of Coated Abrasives

Brown

Brown-coloured coated abrasives often indicate the use of aluminium oxide abrasive. Aluminium oxide is a versatile abrasive material suitable for a wide range of applications, including general metalworking, woodworking, and surface preparation.

Red

Red-coloured coated abrasives may also indicate the use of aluminium oxide abrasive. However, some manufacturers use red to signify a specific type of aluminium oxide with enhanced properties, such as improved cutting performance or durability.

Blue

Blue-coloured coated abrasives are sometimes associated with zirconia alumina abrasive. Zirconia alumina is a tough, long-lasting abrasive material commonly used for heavy-duty grinding and stock removal applications, particularly on hard metals like stainless steel and titanium.

Black

Black-coloured coated abrasives may contain silicon carbide abrasive. Silicon carbide is a hard and sharp abrasive material suitable for applications involving hard or brittle materials such as ceramics, glass, and stone.

Green

Green-coloured coated abrasives are less common but may be associated with specialty abrasives such as ceramic alumina or cubic boron nitride (CBN). These abrasives offer exceptional cutting performance and durability, often used for high-speed grinding applications or when machining challenging materials.

Other Colours

Some manufacturers may use other colours to distinguish specific types of abrasives or coated abrasive characteristics. For example, white or grey coated abrasives may be associated with specialty abrasives like diamond or CBN, which are used for precision grinding applications.

Different Types of Backings Used in Coated Abrasives

Paper

For coated abrasives, highly technical papers are used as substrates. The letters reflecting weight and versatility define them: "A and "B" weights are lightweight and extremely flexible. "C,” "D,” "E,” "F" weights with more strength and less versatility are medium to heavyweight.

Cloth

Cloth backings are more reliable than paper backings. Cotton, polyester, and polyester-cotton combinations are significant types of cloth backings. Weight and versatility determine cloth backings. Cloth backing is ideal for applications of heavy-duty grinding and deburring. It provides excellent stability on edge.

Fiber

A rigid vulcanized material made from rag stock is fiber backing. For abrasive fiber discs, this backing is commonly used. The mixture’s backing is laminated paper and fabric and is very solid and resistant to shock. For a wide variety of grits and mounting methods, combination backings are usually used.

Other Backing Materials

There is also a range of different substrates coated for particular uses, such as nylon fiber or screens. Another substrate that can be used for drying, polishing, or mixing is non-woven nylon impregnated with abrasive grains.

Safety Precautions for Using Coated Abrasives

● Always use eye and face protection such as mask, screen and glasses, hat or head protection, protective clothing, and safety shoes.

● The noise generated by coated abrasive products can exceed 80 dB, meaning prolonged exposure can cause permanent damage to hearing. Use ear protection such as earplugs and anti-noise screen.

● The vibrations generated by coated abrasive products can cause damage to the human body so make sure you adopt work turnovers and resting breaks.

● Carry out a specific evaluation of the noise and vibration risk and adopt suitable protection and precautions.

● Wear protective gloves that fully cover wrists.

● Carry out an evaluation of the physical and chemical risks associated with the use of abrasive products and adopt suitable precautions and protective measures.

● Protect the respiratory tract by wearing a mask with specific filters or air respirator systems.

● Use protective measures of the working environment such as ventilation, filtration and powder/fume suction systems.

● Nearby personnel must be protected with all the above precautions/measures.

Storage and Handling of Coated Abrasives

Keep stockroom at constant levels of humidity (35-50%) and temperature (60-80° F)

Keep cartons away from damp or cold walls and floors where they may absorb moisture

Store coated abrasives away from any heat source

Keep products in original packages for easy handling and stacking

Flap wheels removed from the original packaging should be spread out on a clean shelf, always placed face down, never resting on edge

Fiber discs removed from the original packaging should be stored in a suitable disc holder and kept under pressure

Store bulk rolls flat on shelves or pallets, not on edge

Belts removed from packing case should be rolled up and stood on edge on a clean shelf. They may be draped over a large cylinder but never hang a belt from a nail or peg (the backing will crease and the abrasive coat will crack)

Precondition the coated abrasive products in a humidity and temperature controlled environment before use for maximum efficiency

FAQ

Q: What are coated abrasives?

A: A coated abrasive is a product that consists of a thin layer of abrasive grain attached to a substrate such as paper, cloth, etc. Coated abrasives come in a variety of forms such as sheets, discs, rolls, specialties, or belts.

Q: What is the difference between coated abrasives and bonded abrasives?

A: The key difference between bonded and coated abrasives is the technique employed to join the material to the product. Coated abrasives adhere a layer of abrasive material to the outside surface of the product whereas bonded abrasives are formed by the fusion of abrasive grains and the binder itself.

Q: What three basic parts make up a sheet of coated abrasive?

A: Coated abrasives consist of the following components: An abrasive grain attached to the backing material (i.e., cloth, paper, cotton, polyester) held on with a bonding agent (glue, resin). We will start by taking each of these components: grain, backing & bond.

Q: What is the difference between open and closed coated abrasives?

A: The difference between open and closed coat abrasives are how much of the surface area is covered with abrasive grains. Open coat abrasives are less densely packed with grains compared to closed coat abrasives.

Q: Is sandpaper a coated abrasive?

A: Sandpaper and emery cloth are coated abrasives for hand use, usually non-precision. Other coated abrasive forms include sanding cords, pads, belts, and discs. Variants are available for use by hand or as components for power tools such as sanders, die grinders and belt sanders.

Q: What is the make coat in coated abrasives?

A: The first or “maker” coat adheres the abrasive grain to the backing, ensuring proper anchoring and orientation. After drying or curing, the second or “sizer” coat is applied. The sizer adhesive unites with the maker bond to provide final grain anchoring and proper total-adhesive level for the finished product.
