Abstract
Coated abrasive materials can be made from a substrate and, adhered to the substrate by a maker coat, weak shaped abrasive grits with, interspersed between the abrasive grits, a plurality of non-abrasive particles that are smaller than the abrasive grits which serve to raise the level of a size coat applied over the maker coat and abrasive grits such that the abrasive grits are anchored over a greater part of their length without the need for the application of a large volume of size coat and such that a grinding adjuvant included in the topmost coat is located adjacent the tips of the abrasive grits which perform the grinding when the coated abrasive is in use.
