Abstract:
Provided are abrasive articles in which the make layer, abrasive particle layer, and size layer are coated onto a backing according to a pre-determined coating pattern. All three components are generally in registration with each other, thereby providing a pervasive uncoated area extending across the backing. Advantageously, this configuration provides a coated abrasive that displays superior curl-resistance compared with previously disclosed abrasive articles. Moreover, this configuration resists loading, resists de-lamination, has enhanced flexibility, and decreases the quantity of raw materials required to achieve the same level of performance as conventional abrasive articles.
