Abstract: Systems and methods include providing a coated abrasive article with a substrate formed from a plurality of hygroscopic fibers, an abrasive layer comprising a make coat, a size coat, a supersize coat, or combinations thereof disposed on a first side of substrate, and an anti-curl layer disposed on a second side of the substrate. The polymer-based anti-curl layer allows the coated abrasive article to achieve a change in curl between −5 millimeters and 25 millimeters, the change in curl being expressed as the curl of the coated abrasive article in millimeters at 90% relative humidity minus the curl of the coated abrasive article in millimeters at 20% relative humidity. The coated abrasive article exhibits substantially no loss of grinding performance, burst speed, or a combination thereof as compared to coated abrasive articles free of the anti-curl layer.

Abstract: A sanding system is presented that includes a tool with a motor which, when actuated, drives movement of a drive shaft. The system also includes a backup pad coupled to the drive shaft. The backup pad is configured to receive an abrasive article. Movement of the drive shaft causes movement of the abrasive article. The system also includes a compliant damping unit configured to provide variable compliance for the tool when the abrasive article contacting a worksurface. The system also includes an electronic controller that receives a system operating condition and sends a signal to the compliant damping unit based on the system operating condition.

Abstract: The disclosure relates to layers comprising a body having a thickness, T, comprising a curable composition comprising a polymerizable epoxy-acrylate resin composition and abrasive particles at least partially embedded in the polymerizable epoxy-acrylate resin composition, wherein the body includes a plurality of void spaces free of the curable composition extending into the body from the first major surface and the depth of the plurality of void spaces is at least 10 percent of thickness T. The disclosure also relates to cured compositions formed from such curable compositions and, in turn, abrasive articles made from such cured compositions as well as methods for making abrasive articles.

Abstract: The present disclosure relates to an abrasive article construction containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. In one aspect, the present disclosure provides an abrasive article including a backing with a first major surface and an opposing second major surface, an abrasive layer bonded to at least a portion of the first major surface, with the abrasive layer comprising abrasive particles retained in a make coat. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer.

Abstract: Methods of making an abrasive article. Abrasive particles are loaded to a distribution tool including a plurality of walls defining a plurality of slots. Each slot is open to a lower side of the tool. The loaded particles are distributed from the distribution tool to a major face of a backing web below the lower side and moving relative to the tool. At least a majority of the particles distributed from the tool undergo an orientation sequence in which each particle first enters one of the slots. The particle then passes partially through the slot such that a first portion is beyond the lower side and in contact with the major face, and a second portion within the slot. The sequence then includes the particle remaining in simultaneous contact with one of the walls and the major face for a dwell period while the web moves relative to the tool.

Abstract: Disclosed is an exemplary abrasive pad having a plurality of first elongated members and a plurality of second elongated members arranged crosswise relative to the first elongated members to form a mat having a first side and an opposite second side. The second elongated members alternately pass over and under the first members in a serpentine manner, and include a longitudinal concave region and a longitudinal convex region. The abrasive pad includes an abrasive material affixed to the convex region of at least one of the plurality of second elongated members, wherein the concave region of the second elongated members are devoid of abrasive material.

Abstract: A transport, driving or pressing belt, comprising at least one belt material having a lower and an upper face limited by two longitudinal edges and two transverse edges running obliquely with respect to the main extension direction of the belt, the belt material being closed and the longitudinal edges being folded down, and a method for manufacturing a transport, driving or pressing belt. To ensure high tensile strength over the complete belt length and avoid an edge tearing of the first belt material at the longitudinal edges, the transverse edges of a first belt material lie against each other in abutting relationship, and a second belt material is arranged centrically on the first belt material at least in the region of the transverse edges. The second belt material here nearly covers a width of 50% of the first belt material and is centrically glued with the first belt material.
