Abstract: A coated abrasive belt (100) includes a belt backing (110) and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements (160) secured to at least a portion of a major surface of the belt backing (110) by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal (192) and vertical lines (194) of a rectangular grid pattern. Each abrasive element has at least two triangular abrasive platelets (130), each having respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of the triangular abrasive platelets is disposed facing and proximate to the belt backing A first portion of the abrasive elements is arranged in alternating first rows (16) wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines (194). A second portion of the abrasive elements is arranged in alternating second rows (168) wherein the triangular abrasive platelets (130) are disposed lengthwise aligned with the horizontal lines (194). The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive belt are also disclosed.

Abstract: According to one embodiment, a method of making an abrasive article is disclosed. The method can comprise: providing a surface; disposing magnetizable abrasive particles on the surface; and varying a magnetic field relative to the magnetizable abrasive particles to impart a non-random orientation and/or alignment to the magnetizable abrasive particles relative to the surface.

Abstract: The present disclosure provides an abrasive article (10). The abrasive article (10) has a direction of use, a y-axis and a z-axis orthogonal to the y-axis and the direction of use. The abrasive article (10) further includes a backing (12) and shaped abrasive particles attached to the backing. About 5% to about 100% of the shaped abrasive particles (14) independently include a first side surface (16), a second side surface (18) opposed to the first side surface (16), a leading surface (20) connected to the first side surface (16) at a first edge (24) and connected to the second side surface (18) at a second edge (26), a rake angle (30) between the backing (12) and the leading surface (20) in a range of from about 10 degrees to about 110 degrees, and a z-direction rotational angle (50) between a line (52) intersecting the first edge (16) and second edge (18) and the direction of use (22) of the abrasive article (10) in a range of from about 10 degrees to about 170 degrees.

Abstract: In some examples, an abrasive particle transfer system including a production tool including a dispensing surface with a plurality of cavities formed therein; abrasive particles removably disposed within at least some of the cavities; and a nonwoven substrate having an outer surface opposing the dispensing surface of the production tool, wherein the dispending surface of the production tool is configured to apply a compressive force to the outer surface of the nonwoven substrate to compress the nonwoven substrate from a first thickness to a second thickness, wherein, while the nonwoven substrate is compressed to the second thickness by the production tool, the abrasive particles are transferred from the plurality of cavities to the nonwoven substrate.

Abstract: A method of making magnetizable abrasive particles includes: moistening the outer surfaces of ceramic particles with waterglass to provide moistened ceramic particles. Magnetizable particles are contacted with the moistened ceramic particles to provide powder-coated ceramic particles. The powder-coated ceramic particles are heated to at least a temperature sufficient to bond the magnetizable particles of the powder-coated ceramic particles to the respective ceramic particles thereby providing the magnetizable abrasive particles. On a respective basis, each magnetizable abrasive particle comprises a respective ceramic particle having a magnetizable particles bonded thereto.

Abstract: A phenolic resin composition is described comprising at least 50 wt.-% of phenolic resin; first polymerized units comprising a cationic group; and second polymerized units comprising an anionic group. The cationic groups are ionically bonded to the anionic groups. The ionic bonding of the cationic group and anionic group of the polymerized units can provide certain complex viscosity and/or tan delta properties. In some embodiments, the phenolic resin composition has a complex viscosity at 65C of at least 50 Pascal(seconds) and/or has a tan delta at 65C ranging from 0.5 to 2.5. Abrasive articles and methods of making an abrasive article are also described.
