Abstract
A method of making a coated abrasive article, the method comprising: providing a backing, providing a curable abrasive slurry having a homogeneous dispersal of abrasive particles, applying the abrasive slurry to at least part of a major surface of the backing and forming a surface texture in the slurry, wherein the abrasive slurry is capable of maintaining the homogeneous dispersal of abrasive particles and the surface texture in an uncured state.

A method of making a coated abrasive article, the method comprising:
- providing a backing,
- providing a curable abrasive slurry having a homogeneous dispersal of abrasive particles,
- applying the abrasive slurry to at least part of a major surface of the backing and forming a surface texture in the slurry,
- wherein the abrasive slurry is capable of maintaining the homogeneous dispersal of abrasive particles and the surface texture in an uncured state.
7-11. (canceled)
A coated abrasive article comprising:
- a backing having first and second opposed major surfaces;
- a cured abrasive slurry disposed on the first major surface of the backing, wherein the cured abrasive slurry has a textured major surface opposite the backing, wherein the textured major surface comprises a first interconnected network of interconnected first ridges, wherein at least some of the interconnected first ridges meet at first intersection points, and wherein outwardly extending first spikes are disposed proximate to at least a portion of the first intersection points.
A coated abrasive article comprising:
- a backing having first and second opposed major surfaces;
- a textured coating disposed on the first major surface of the backing, wherein the textured coating has a textured major surface opposite the backing, wherein the textured major surface comprises a network of ridges arranged in a herringbone pattern.
A coated abrasive article comprising:
- a backing having first and second opposed major surfaces;
- a textured coating disposed on the first major surface of the backing, wherein the textured coating has a textured major surface opposite the backing, wherein the textured major surface comprises a plurality of discreet depositions of abrasive slurry.
