Abstract
This invention provides a method of making an abrasive article. The method of this invention comprises the steps of: PA1 a. providing a backing having a front surface; PA1 b. providing a radiation energy transmissive production tool having a contacting surface; PA1 c. applying a mixture comprising a plurality of abrasive particles and a binder precursor onto the contacting surface of the production tool; PA1 d. causing the mixture on the contacting surface of the production tool to come into contact with the front surface of the backing such that the mixture wets the front surface of the backing; PA1 e. transmitting radiation energy through the production tool to at least partially cure the binder precursor to form a shaped, handleable structure; and PA1 f. separating the shaped, handleable structure from the production tool. The shaped, handleable structure can be fully cured to form a coated abrasive article.
