ABRASIVE PRODUCTS

摘要

Coated abrasive materials can be made from a backing material and, adhered to the backing by a maker coat, weak shaped abrasive particles with, interspersed between the abrasive particles, a plurality of non-abrasive particles that are smaller than the abrasive particles which serve to raise the level of a size coat applied over the maker coat and abrasive particles such that the abrasive particles 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 particles which perform the grinding when the coated abrasive is in use.
