Coated Abrasives Basics

The page begins with a practical overview of major abrasive grains used in coated products, including emery, garnet, silicon carbide, multiple aluminum oxide types, zirconia alumina and ceramic alumina. Each grain is linked to typical substrates and stock-removal behavior.

It then explains the three main backing classes: paper for economical finishing, cloth for flexibility and strength, and fiber for resin fiber discs. Together with the make coat and size coat bond system, these backings define flexibility, heat resistance and grain retention.

Finally, the article contrasts open coat and closed coat structures. Open coat leaves space between grains to reduce loading, while closed coat maximizes material removal and life. That is exactly the kind of product education many buyers need at category level.
