Abstract
An abrasive article includes a backing; a make coat overlying the backing; and a plurality of abrasive particles overlying the backing and at least partially contained in the make coat; and a make coat thickness ratio (Tg/Ta) of not greater than 1.5, wherein Tg is the average thickness of the make coat at the sides of the abrasive particles and the Ta is the average thickness of the make coat.
Claims32
An abrasive article comprising:
- a backing;
- a make coat overlying the backing;
- a plurality of abrasive particles overlying the backing and at least partially contained in the make coat;
- a make coat thickness ratio (Tg/Ta) of not greater than 1.5, wherein Tg is the average thickness of the make coat at the sides of the abrasive particles and Ta is the average thickness of the make coat;
- wherein the abrasive particles include shaped abrasive particles or elongated abrasive particles, and where each of the shaped abrasive particles or elongated abrasive particles include a body having a length (l), a width (w) and a thickness (t), wherein the width>thickness and the length>thickness;
- and
- wherein each of the shaped abrasive particles or elongated abrasive particles of the plurality of shaped abrasive particles or elongated abrasive particles bodies have at least 3 exterior corners and at least 3 interior corners, wherein each of the interior corners have an interior corner angle value greater than any of exterior corner angle values of any of the at least 3 exterior corners.
