Rio Tinto Alcan

It basically consists in gluing a layer of abrasive grains onto a flexible support (paper or cloth). A base coat (generally phenolic resin) does ensure the proper attachment of the grains to the support while a size coat (onto the grains) will better hold them during the grinding operation. Various shapes of tools can be found, like belts, discs, flap wheels, paper, Sometimes, on very loading materials (like paints) a supersizing is sprayed to extend the cutting efficiency of the tools.
