A coated abrasive article comprising a backing, an adhesive layer disposed in a discontinuous distribution on at least a portion of the backing, wherein the discontinuous distribution comprises a plurality of adhesive contact regions and at least one shaped abrasive particle is disposed on a majority of each of the discrete adhesive contact regions, wherein at least 50% of the shaped abrasive particles comprise a predetermined side orientation and have a tilt angle of at least 45 degrees, wherein the shaped abrasive particles comprise a polycrystalline material and are free of binder, wherein the first plurality of discrete adhesive contact regions comprise a predetermined two-dimensional shape as viewed from above, and wherein each of the discrete contact regions comprises a length, a width, or a combination thereof that substantially corresponds to a dimension of the at least one abrasive particle.

Abrasive particles having particular shapes and methods of forming such particles

An abrasive article having a plurality of apertures arranged in a non-uniform distribution pattern, wherein the pattern is spiral or phyllotactic, and in particular those patterns described by the Vogel equation. Also, provided is a back-up pad having a spiral or phyllotactic patterns of air flow paths, such as in the form of open channels. The back-up pad can be specifically adapted to correspond with an abrasive article having a non-uniform distribution pattern. Alternatively, the back-up pad can be used in conjunction with conventional perforated coated abrasives. The abrasive articles having a non-uniform distribution pattern of apertures and the back-up pads can be used together as an abrasive system.

Abrasive article having a non-uniform distribution of openings

A coated abrasive article comprising a backing, an adhesive layer disposed in a discontinuous distribution on at least a portion of the backing, wherein the discontinuous distribution comprises a plurality of adhesive contact regions having at least one of a lateral spacing or a longitudinal spacing between each of the adhesive contact regions; and at least one abrasive particle disposed on each adhesive contact region, the abrasive particle having a tip, and there being at least one of a lateral spacing or a longitudinal spacing between each of the abrasive particles, and wherein at least 65% of the at least one of a lateral spacing and a longitudinal spacing between the tips of the abrasive particles is within 2.5 standard deviations of the mean.

An abrasive article comprising a nonwoven substrate material having a top surface and a bottom surface; a woven cloth; a thermoplastic fastener; and a plurality of abrasive particles, wherein the cloth layer is adhered to the top surface of the nonwoven substrate material; wherein the thermoplastic fastener is disposed on the cloth, and wherein the plurality of abrasive particles are disposed on at least the bottom surface of the nonwoven abrasive substrate.
