Abrasive products

摘要

Coated abrasive materials can be made from a backing material (1) and, adhered to the backing by a maker coat (2), weak shaped abrasive particles (3) with, interspersed between the abrasive paricles (3), a plurality of non-abrasive particles (4) that are smaller than the abrasive particles (3) which serve to raise the level of a size coat (6) applied over the maker coat (2) and abrasive particles (3) such that the abrasive particles (3) are anchored over a greater part of their length without the need for the application of a large volume of a size coat (6) and such that a grinding adjuvant included in the topmost coat (5) is located adjacent the tips of the abrasive particles (3) which perform the grinding when the coated abrasive is in use. <IMAGE>
