A coated abrasive article including a body having a backing including a spunlace polyester-based material and a saturant contained in the spunlace polyester-based material, the saturant including a material selected from the group of phenolic resin, acrylic, urea resin, and a combination thereof, and an abrasive layer overlying the backing including abrasive particles.

A method for producing a coated abrasive includes producing or providing an intermediate abrasive product that comprises a substrate, a plurality of abrasive grains that are bonded to the substrate, and at least one layer of an uncured size coat that at least partially covers the abrasive grains with the uppermost size coat being uncured. The method further includes applying at least one grinding additive to the uppermost, uncured size coat with the grinding additive applied to the size coat in dry form. The method also includes curing the uppermost size coat. A coated abrasive is produced by the method and the coated abrasive is used to process a surface.

The present invention is a fixed-abrasive-grain wire including a core wire and abrasive grains fixed on a surface of the core wire, wherein an abrasive grain density is 1200 grains/mm.sup.2 or more, where the abrasive grain density is the number of the abrasive grains per unit area on the surface of the core wire, and 2% or less of all distances between centroids of the abrasive grains are equal to or shorter than an average circle equivalent diameter of the whole abrasive grains. There can be provided a fixed-abrasive-grain wire, a wire saw, and a method for slicing a workpiece that can suppress meandering of the fixed-abrasive-grain wire during slicing a workpiece and improve TTV and warp of wafers sliced from the workpiece.

A coated abrasive article having a plurality of formed ceramic abrasive particles each having a surface feature. The plurality of formed ceramic abrasive particles attached to a flexible backing by a make coat comprising a resinous adhesive forming an abrasive layer. The surface feature having a specified z-direction rotational orientation, and the specified z-direction rotational orientation occurs more frequently in the abrasive layer than would occur by a random z-direction rotational orientation of the surface feature.

A method for producing a coated abrasive includes producing or providing an intermediate abrasive product that comprises a substrate, a plurality of abrasive grains that are bonded to the substrate, and at least one layer of an uncured size coat that at least partially covers the abrasive grains with the uppermost size coat being uncured. The method further includes applying at least one grinding additive to the uppermost, uncured size coat with the grinding additive applied to the size coat in dry form. The method also includes curing the uppermost size coat. A coated abrasive is produced by the method and the coated abrasive is used to process a surface.

An abrasive article having a removable support sheet having a first major surface. An image layer containing inks applied over the first major surface. A polyurethane backing layer having a first major backing surface located adjacent to the image layer and a second major backing surface opposite the first major surface. A functional layer comprising an abrasive layer applied to the second major surface; the abrasive layer comprising a make coat, abrasive particles and a size coat.

A coated abrasive article (100) comprises: a backing (110) comprising polyester and having a major surface (115); a tie layer (120) directly bound to at least a portion of the major surface (115); and an abrasive layer (130) directly bound to at least a portion of the tie layer (120), the abrasive layer (130) comprising abrasive particles (160) and at least one binder resin (140). The tie layer (120) comprises an at least partially cured blend of, on a solids basis, from 50 to 99 parts by weight of at least one styrene-butadiene copolymer latex and from 1 to 50 parts by weight of at least one resorcinol-formaldehyde resin. A treated backing (110) comprising polyester having the preceding tie layer (120) directly bound thereto is also disclosed.

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.

An abrasive article including: a backing layer including a front fill overlying a backing, wherein the backing layer including the front fill comprises (1) a surface roughness of not greater than 100 microns or (2) an average thickness/roughness ratio of greater than 0.80; a make coat overlying the backing layer; and a plurality of abrasive particles overlying the backing layer, wherein at least 65% of the abrasive particles have a well-oriented tilt orientation.
