Abrasive particles having particular shapes and methods of forming such particles
First Claim
1. A coated abrasive article comprising:
- a backing;
an adhesive layer disposed in a discontinuous distribution on at least a portion of the backing, wherein the discontinuous distribution comprises a first plurality of discrete adhesive contact regions; and
at least one shaped abrasive particle disposed on a majority of each of the discrete adhesive contact regions,wherein at least 50% of the shaped abrasive particles comprise a predetermined side orientation and have a tilt angle of at least 45 degrees,wherein the shaped abrasive particles comprise a polycrystalline material and are free of binder,wherein the first plurality of discrete adhesive contact regions comprise a predetermined two-dimensional shape as viewed from above,wherein each of the discrete contact regions comprises a length, a width, or a combination thereof that substantially corresponds to a dimension of the at least one abrasive particle, andwherein one to three shaped abrasive particles are disposed on the adhesive contact regions.
