Abstract: An abrasive article comprises a porous substrate having openings extending through the porous substrate between first and second opposed major surfaces. An abrasive coating is disposed on only a portion of a first major surface of the porous substrate. The abrasive coating comprises a functional layer disposed on only a portion of a first major surface of the porous substrate, a make layer disposed on at least a portion of the functional layer opposite the porous substrate, and abrasive particles. The functional layer and the make layer independently comprise chemically crosslinked binders. The functional layer fully occludes a first portion the openings and does not fully occlude a second portion of the openings, which permits passage of abraded swarf through the abrasive article. Methods of making the abrasive article are also disclosed.
