    摘要: A coated abrasive article comprises a backing having first and second opposed major surfaces. A make layer is bonded to the first major surface. Agglomerate grinding aid particles are directly bonded to the make layer. At least a portion of the agglomerate grinding aid particles comprise grinding aid particles retained in a binder, and are arranged according to an open predetermined pattern. Abrasive particles are directly bonded to the make layer in spaces between the agglomerate grinding aid particles. A size layer is directly bonded to the make layer, agglomerate grinding aid particles, and abrasive particles. A method of making a coated abrasive article, in which the agglomerate grinding aid particles are deposited onto a curable make layer precursor prior to depositing abrasive particles onto the curable make layer precursor in spaces between the agglomerate grinding aid particles is also disclosed.

    摘要: An abrasive article includes a first plurality of abrasive particles and a second plurality of abrasive particles. The first plurality of abrasive particles differ in at least one of a size, an average weight and a shape from the second plurality of abrasive particles. The first plurality of abrasive particles are spaced from the second plurality of abrasive particles by at least a minimum distance in the x-axis direction, and both the first plurality of abrasive particles and the second plurality of abrasive particles extend in similar paths to one another with respect to the y-axis.

    摘要: A method of making a mesh abrasive product comprises sequentially: 1) providing a production tool having a mold surface defining a plurality of shaped cavities and filling at least some of the shaped cavities with an abrasive composite precursor slurry, wherein the abrasive composite precursor slurry comprises abrasive particles dispersed within a curable binder precursor; 2) contacting the mold surface with an open mesh backing comprising interwoven threads defining openings, and having first and second opposed major sides; 3) ultrasonically vibrating the abrasive composite precursor slurry; 4) curing the curable binder precursor by exposing it to sufficient actinic electromagnetic radiation to provide isolated shaped abrasive composites contacting and secured to the first major side of the open mesh backing; and 5) separating the mesh abrasive product from the production tool. An open mesh abrasive product preparable by the method is also disclosed.

    摘要: 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.

    摘要: The disclosure relates to an abrasive article that includes a fabric substrate comprising strands forming first void spaces between the strands. The fabric substrate comprising an abrasive side and an attachment side. The abrasive article also includes a coating on the attachment side. The abrasive article also includes a make layer joined to the fabric substrate on the abrasive side. The abrasive article also includes abrasive particles joined to the make layer. The abrasive article also includes a plurality of second void spaces extending through the make layer coinciding with first void spaces in the fabric substrate. The coating on the fabric substrate is both hydrophobic and lipophobic. The attachment side of the fabric substrate is substantially free of make layer.
