Abstract
A coated abrasive article comprising a backing and abrasive particles overlying the backing, the abrasive particles having a random rotational orientation and at least 87% of the abrasive particles are oriented at a tilt angle within a range of greater than 44 degrees to 90 degrees, and not greater than 13% of the abrasive particles are oriented at a tilt angle of not greater than 44 degrees.
Claims20
A coated abrasive article comprising:
- a backing;
- and
- abrasive particles overlying the backing, wherein the abrasive particles have a random rotational orientation and at least 87% of the abrasive particles are oriented at a tilt angle of greater than 44 degrees, and wherein not greater than 13% of the abrasive particles are oriented at a tilt angle within a range of 0 degrees to 44 degrees.
A coated abrasive article comprising:
- a backing;
- abrasive particles overlying the backing, wherein the abrasive particles have a random rotational orientation, and wherein a first portion (P1) of the abrasive particles have an upright orientation having a tilt angle within a range of greater than 71 degrees to 90 degrees, a second portion (P2) of the abrasive particles have a slanted orientation having a tilt angle within a range of greater than 44 degrees to 71 degrees, and wherein the abrasive particles have a primary orientation value (P1/P2) of at least 2.5.
