In step c), a mixture of magnetizable non-magnetizable particles is passed through the applied magnetic field and onto the make layer precursor such that the magnetizable and non-magnetizable particles are predominantly deposited onto the web in a drop zone according to a predetermined order. At least one of the magnetizable particles or the non-magnetizable particles comprises abrasive particles. In step d), the make layer precursor is at least partially cured to provide a make layer.

An abrasive product having an abrasive surface, a belt of an abrasive product, a roll of an abrasive product and a method for manufacturing an abrasive product. An abrasive product includes a backing and an abrasive surface. The abrasive surface includes at least a first abrasive area and a second abrasive area, wherein abrasive properties of the first abrasive area are different from abrasive properties of the second abrasive area.

According to one embodiment, a method of making an abrasive layer on a backing is disclosed. The method can comprise: providing dispensable magnetizable abrasive particles and a distribution tool, wherein the distribution tool is configured to receive the magnetizable abrasive particles therein, and wherein the distribution tool is configured to impart at least one of a predetermined orientation and alignment of the magnetizable abrasive particles, positioning a backing adjacent to the distribution tool and spaced therefrom by a gap, applying a magnetic field to at least the backing and a portion of the gap between the backing and the distribution tool, and transferring the magnetizable abrasive particles from the distribution tool to a first major surface of the backing, wherein the magnetic field is applied during the transfer of the magnetizable abrasive particles.

The present disclosure provides an abrasive article. The abrasive article includes a base. The abrasive article further includes a plurality of soft shaped abrasive particles distributed about the base.

A method of applying magnetizable particles onto an adherent web includes several steps. Step a) provides a magnetizable particle coating apparatus comprising a downward sloping dispensing surface at least partially disposed within an applied magnetic field. Step b) disposes an adherent web between upper and lower magnetic members and beneath the downward sloping dispensing surface, wherein the web comprises a backing having a curable binder precursor layer disposed on a major surface thereof. Step c) disposes magnetizable particles onto at least a portion of the downward sloping dispensing surface within the applied magnetic field, and subsequently disposed onto the curable binder precursor layer while the adherent web is advanced from an upweb position to a downweb position. Step d) at least partially cures the curable binder precursor layer to fix the orientations of the magnetizable particles.

Systems and methods include providing a coated abrasive article with an enhanced anti-loading composition in a supersize coat. The anti-loading composition includes a mixture of a metal stearate, at least one performance component, and a polymeric binder composition.

A coated abrasive disc includes a disc backing and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements secured to a major surface of the disc backing by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern. Each abrasive element has two triangular abrasive platelets, 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 disc backing. A first portion of the abrasive elements is arranged in alternating first rows wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines. A second portion of the abrasive elements is arranged in alternating second rows wherein the triangular abrasive platelets are disposed lengthwise aligned with the horizontal lines. The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive disc are also disclosed.

Method for manufacturing a non-woven abrasive article, and non-woven fibers are made of a certain starting material and are subjected to method steps of forming a non-woven web, then consolidating the non-woven web. In order to improve the homogeneity, as well as the reproducibility of the non-woven abrasive article manufactured, the non-woven fibers, prior to the method step of forming a non-woven web and/or prior to the method step of consolidating the non-woven web, are coated with abrasive grains in such a way that the abrasive grains adhere to the certain starting material.
