How sandpaper is made
Production starts when the make coat is applied to one side of the backing material. The term "sandpaper" is a misnomer, since most coated abrasives contain neither sand nor paper. Instead, a typical coated abrasive contains a backing of cotton, polyester, or rayon, with an initial layer of adhesive backing—the make coat—applied to it.
