    Abstract: A method of making a coated abrasive article includes disposing a precursor make layer on a major surface of the backing, optionally partially curing the precursor make layer to provide a partially cured precursor make layer, disposing abrasive particles; partially embedding abrasive particles in the optionally partially cured precursor make layer; and further curing the optionally partially cured precursor make layer to form a make layer. The precursor make layer comprises components comprising: a) 50 to 97.99 percent by weight of phenol-formaldehyde resin; b) 1 to 49 percent by weight of resorcinol- formaldehyde resin; c) 1 to 49 percent by weight of at least one compound having at least one free- radically polymerizable group; and d) 0.01 to 1 percent by weight of a free-radical initiator. A size layer and/or supersize layer may be disposed over the make layer and abrasive articles. Coated abrasive articles made by the method are also disclosed.

    Abstract: An open coat abrasive article includes a backing having first and second opposed major surfaces, a make coat resin on at least one major surface of the backing, abrasive particles arranged on the backing at least partially embedded in the make coat resin, and a size coat resin on the first resin and the abrasive particles, wherein the shaped abrasive particles have an average peak count of no greater than about 40,000 per 24 in 2 . A method of abrading in a body-in-white application is also disclosed.

    Abstract: An abrasive article comprises: a substrate comprising strands forming first void spaces between strands; a laminate joined to the substrate, wherein the laminate comprises a surface opposite to the substrate; a resin composition joined to the surface of the laminate. First and second portions of the surface of the laminate have respective first and second surface free energies that are different. Another abrasive article comprises: a substrate comprising strands forming first void spaces between strands; a laminate joined to the substrate, wherein the laminate comprises a first polymer and a second polymer; a resin composition joined to the laminate; In both embodiments, abrasive particles are joined to the resin composition, and a plurality of second void spaces extends through the laminate coinciding with first void spaces in the porous substrate. A method of making abrasive articles is also disclosed.

    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.
