Polymer bond abrasive articles including continuous polymer matrix, and methods of making same

Abstract

A polymer bond abrasive article is formed of a continuous photocured polymer matrix having abrasive particles retained therein. The photocured polymer matrix includes at least one of an optical brightener or a light absorber, and the polymer bond abrasive article has a three-dimensional shape. An abrasive tool includes the abrasive article affixed to a shaft or a pad. Further, a method of making the polymer bond abrasive article includes a) obtaining a photocurable composition liquid dispersion; b) selectively curing a portion of the photocurable composition; and repeating steps a) and b) to form the polymer bond abrasive article. The dispersion contains at least one photocurable component; abrasive particles; a photoinitiator; and at least one of an optical brightener or a light absorber.
