Abstract
An abrasive article including: a backing layer including a front fill overlying a backing, wherein the backing layer including the front fill comprises (1) a surface roughness of not greater than 100 microns or (2) an average thickness/roughness ratio of greater than 0.80; a make coat overlying the backing layer; and a plurality of abrasive particles overlying the backing layer, wherein at least 65% of the abrasive particles have a well-oriented tilt orientation.
Claims19
An abrasive article comprising:
- a backing layer including a front fill overlying a backing, wherein the front fill is a discrete layer having a thickness different from the backing layer, wherein the front fill comprises an average thickness and an average roughness and an average thickness/roughness ratio of at least 0.80 and not greater than 15;
- a make coat overlying the backing;
- and
- a plurality of abrasive particles overlying the backing layer, wherein the plurality of abrasive particles comprises a standing portion of abrasive particles (Pst) having a tilt angle of 65 degrees to 90 degrees, and wherein the plurality of abrasive particles comprises a fallen portion (Pf) having a tilt angle of 0 to 5 degrees, and further comprising a ratio of the standing portion relative to the fallen portion (PSt/Pf) of at least 2.0.
