ABSTRACT:
Replacement of all or most of the coarse mineral in a coated abrasive product by a superior (and typically more expensive) mineral improves abrading performance significantly more than would be predicted. In some cases the performance is superior to that of products made with either mineral alone. The mineral is typically applied in two layers, substantially all of the coarse mineral being applied in the second layer. Superiority is defined in terms of a test that measures the comparative ability of different minerals to abrade cold rolled steel.
