    Abstract: The method generally involves the steps of filling the cavities in a production tool each with an individual abrasive particle. Aligning a filled production tool and a resin coated backing for transfer of the abrasive particles to the resin coated backing. Transferring the abrasive particles from the cavities onto the resin coated backing and removing the production tool from the aligned position with the resin coated backing. Thereafter the resin layer is cured, a size coat is applied and cured and the coated abrasive article is converted to sheet, disk, or belt form by suitable converting equipment.

    Abstract: An abrasive belt having a backing and an abrasive layer adhered to the backing by a make coat resin and the abrasive layer comprising a plurality of shaped abrasive particles. A first belt side and a second belt side opposing the first belt side with the first and second belt sides generally aligned with a longitudinal axis of the grinding belt. The belt having at least 30% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 degrees and less than or equal to 20 degrees.

    Abstract: Electrically conductive articles are provided, including a composite including (a) a resin, and (b) electrically conductive shaped particles distributed in the resin, the particles having a monosized distribution. Each particle has a shape including at least a first surface and a second surface intersecting the first surface at an angle a between about 5 degrees and about 150 degrees. The composite has a thickness and often each of the electrically conductive shaped particles distributed in the resin is oriented within the resin such that the particle does not extend beyond the thickness of the composite. A method for making an electrically conductive article is also provided, including (a) providing electrically conductive shaped particles having a monosized distribution, and (b) distributing the particles into a resin to form a composite.
