Adhesives are used to bond the abrasive grains to a soft or hard backing material, a well-known example being sandpaper. When bonding abrasive products, the main effect of the binder is to use as a structural adhesive. This function is to bond the abrasive particles to each Other in a desired spatial relationship to provide mechanical strength and maintain the integrity of the composite. The commonly used grinding wheel is mainly bonded with a phenolic resin adhesive.
A one-component epoxy adhesive (MIL-A-862 Type III) with dicyandiamide as the curing agent is used to adhere powder or granular abrasives to solid or hollow metal shafts.
