Method for Producing a Coated Grinding Means, Coating Grinding Means, and Use of a Coated Grinding Means

摘要

A method for producing a coated abrasive includes producing or providing an intermediate abrasive product that comprises a substrate, a plurality of abrasive grains that are bonded to the substrate, and at least one layer of an uncured size coat that at least partially covers the abrasive grains with the uppermost size coat being uncured. The method further includes applying at least one grinding additive to the uppermost, uncured size coat with the grinding additive applied to the size coat in dry form. The method also includes curing the uppermost size coat. A coated abrasive is produced by the method and the coated abrasive is used to process a surface.
