BACKINGLESS ABRASIVE ARTICLE

摘要

A method of making an abrasive article comprises the steps of forming an abrasive layer having first and second major sides, the abrasive layer including a blend of a polymer formulation and abrasive grains; patterning the first major side of the abrasive layer to define a set of protrusions extending from a first surface of the abrasive article, and disposing an adhesive layer on the second major side of the abrasive layer, wherein the polymer formulation includes a silicone resin, and wherein the abrasive layer has a total height not greater than 1.27 mm (50 mils), the set of protrusions extend not greater than 508 microns (20 mils), and the ashesion layer is in direct contact with the second major side, the adhesion layer defining a second surface of the abrasive article.
