    Abstract: A method for making an abrasive article having at least two abrasive coatings having different abrasive natures. The abrasive natures can differ, for example, by abrasive particle size, abrasive particle type, abrasive particle shape, filler, surfactant, or coupling agent. In another embodiment, the abrasive article can be a structured abrasive article comprising abrasive composites. In another aspect of the invention, the article can have a coating having a single abrasive nature, where the composites comprising the coating are free of abrasive particles.

    Abstract: An abrasive element comprising a substrate having on a surface thereof particles of an abrasive material secured by an organic binding medium wherein at least the surface of the element between the particles of abrasive material contains a fluorochemical selected from the group consisting of compounds comprising a fluorinated aliphatic group attached to a polar group or moiety and compounds having a molecular weight of at least 750 and comprising a non-fluorinated polymeric backbone having a plurality of pendant fluorinated aliphatic groups, said aliphatic groups comprising the higher of(a) a minimum of three C--F bonds, or(b) in which 25% of the C--H bonds have been replaced by C--F bonds such that the compound comprises at least 15% by weight of fluorine.The compound may be applied as a layer coated over the existing layers of an abrasive element or it may be incorporated into at least the coating formulation which will form the outermost layer of the binding medium. The abrasive elements may be in the form of sheets, blocks, discs, pads, belts etc. The presence of the compound serves to reduce the loading of the abrading surface in use, thereby extending the working life of the abrasive element.
