Abstract:
A coated abrasive article having a plurality of formed ceramic abrasive particles each having a surface feature. The plurality of formed ceramic abrasive particles attached to a flexible backing by a make coat comprising a resinous adhesive forming an abrasive layer. The surface feature having a specified z-direction rotational orientation, and the specified z-direction rotational orientation occurs more frequently in the abrasive layer than would occur by a random z-direction rotational orientation of the surface feature.
