ABRASIVE PRODUCT WITH AN EMBOSSED BACKING AND METHOD OF MAKING THE SAME

摘要

The invention provides an abrasive product having a sheet-like backing (11) including a plurality of concavoconvex portions, the backing (1) also having a first major surface including convex portions and an opposite second major surface including concave portions opposite said convex portions. A coating of a binder (12) is applied over the first major surface and the convex portions. A single layer of a plurality of substantially erectly oriented abrasive particles (13) is bonded to the backing (11) by the binder coating (12). The abrasive product is made by providing the backing (11) as defined, coating the first major surface with an uncured composition which will cure to provide the binder (12), applying abrasive particles (13) to the uncured composition coating with an electrostatic sprayer and curing the uncured composition to provide the binder coating (12).
