Coated Abrasives

Abrasive grains are used to make coated abrasives products such as sandpaper and are available in sheets, discs, rolls, belts, pads, flap wheels, and other forms. In coated abrasives, the abrasive grain is adhered to a cloth, fiber, paper or polyester film by a resin or glue bond. The high hardness of the abrasive grain and its angular sharp edges constantly exposes new edges to the work piece, making the coated abrasive excellent at sanding, polishing, finishing and taking off rough edges. Abrasive grains should exhibit high capillarity for instant adhesion to resin or glue bonds
