Abstract

An abrasive article includes a substrate having opposed first and second surfaces, a make coat on at least a portion of the first surface, abrasive mineral particles on at least a portion of the make coat to provide an abrasive surface and a size coat arranged over at least a portion of the abrasive surface, wherein the size coat has a Young's modulus of less than 100,000 psi.

Claims (21)

1. An abrasive article, comprising:

(a) a substrate having opposed first and second surfaces;
(b) a make coat on at least a portion of said first surface;

(c) abrasive mineral particles on at least a portion of said make coat to provide an abrasive surface; and (d) a size coat arranged over at least a portion of said abrasive surface, said size coat having a Young's modulus less than 100,000 psi.
2. An abrasive article as defined in claim 1, wherein the substrate is resilient.
3. An abrasive article as defined in claim 1, wherein the substrate is continuous.
