Coated abrasives products, such as sandpaper, are made from abrasive grains bonded to a flexible substrate using adhesives which are available in sheets, discs, rolls, belts, pads, flap wheels, and other forms. The abrasive grain is bonded to a cloth, fiber, paper, or polymer film by a resin or adhesive bond in coated abrasives. The coated abrasives’ high hardness and angular sharp edges regularly expose new edges to the work item, making it ideal for sanding, polishing, finishing, and removing rough edges. For fast attachment to resin or adhesive bonding, abrasive grains should have a high conductivity.
