A method for making an abrasive article having at least two abrasive coatings having different abrasive natures. The abrasive natures can differ by virtue of abrasive particle size, abrasive particle type, abrasive particle shape, filler, surfactant, or coupling agent. Particularly, the abrasive article can be a structured abrasive article comprising abrasive composites. The abrasive nature of the abrasive composites can differ by virtue of composite shape or size. |
