Product Categories
Paper-backed abrasives
These products are made by bonding abrasive grains to a paper backing using a resin or glue. Paper-backed abrasives are suitable for sanding and finishing applications on wood, metal, and other materials. They are available in various grit sizes, ranging from coarse to fine.
Cloth-backed abrasives
In this category, abrasive grains are bonded to a cloth backing using a resin or adhesive. Cloth-backed abrasives are more durable than paper-backed products and are suitable for heavy-duty sanding and grinding applications. They are commonly used in metalworking and automotive repair.
Film-backed abrasives
These products consist of abrasive grains coated onto a thin film backing. Film-backed abrasives are highly flexible and are suitable for contour sanding and finishing. They are commonly used in the electronics and automotive industries.
In Addition
Coated abrasives can also be classified based on the type of abrasive grain used. Silicon carbide, aluminum oxide, and zirconia alumina are some of the commonly used abrasive grains. Each of these grains has its unique characteristics, making them suitable for specific applications.

Frequently Asked Questions
What factors affect the performance of coated abrasives?
- Abrasive grain type and size: Different abrasive grains have varying levels of hardness, toughness, and friability, which can affect the cutting rate, finish quality, and wear resistance.
- Backing material and weight: The backing material and weight can influence the flexibility, durability, and support of the abrasive grains, as well as the compatibility with the attachment system (e.g., hook-and-loop, PSA).
- Bonding resin or adhesive: The bonding resin or adhesive can affect the integrity, strength, and heat resistance of the abrasive material, as well as the adhesion to the backing material.
- Operating conditions: The operating conditions, such as the speed, pressure, coolant, and abrasive grit sequence, can also affect the performance of the coated abrasive and the workpiece.
How can I choose the right coated abrasive for my application?
- Workpiece material and shape: Different materials and shapes may require specific abrasive types, sizes, and grits to achieve the desired result.
- Surface finish requirements: Depending on the application, you may need a coarse, medium, or fine abrasive to achieve the desired surface finish.
- Application method: Different tools and machines may require specific abrasive forms and sizes to fit and operate correctly.
- Operating conditions: Depending on the operating parameters, such as the speed, pressure, and coolant, you may need a specific abrasive material or bond type to maximize performance and minimize damage or wear.
How can I store and handle coated abrasives properly?
- Store coated abrasives in a dry, clean, and temperature-controlled area to avoid exposure to moisture, dust, or heat, which can damage the backing, bond, or abrasive grains.
- Keep coated abrasives in their original packaging or labeled containers to avoid confusion or contamination with other abrasive types or sizes.
- Handle coated abrasives with care and use proper protective gear, such as gloves, eye protection, and dust masks, to avoid injuries or exposure to dust or chemicals.
