Abstract: A backing material for use in fabricating flexible abrasive sheets. The backing material comprises a flexible web substrate preferably of tough impregnated paper, having on one surface a heat-activatable binder coating which is a non-tacky solid at ambient temperatures and which coating when heated to a temperature insufficient to thermally degrade the substrate is softened and converted to a viscous fluid condition so that when abrasive grit is deposited on the softened coating and electrostatically aligned, the grit by virtue of its weight alone, i.e. by gravity, will sink into the coating to a depth which provides a firm bond with the coating after the heat is removed and the coating resets to its solid non-tacky state. The abrasive sheet products which result when the described backing material is used in the fabrication of such products is also defined.
