Abstract
An abrasive article comprising a substrate having a first major surface and an adhesive layer having abrasive particles embedded therein coated on the first major surface of the substrate, the adhesive layer comprising a hot melt adhesive comprising a polymer cross-linked via hydrolyzed or condensed silyl groups; and a method of preparing an abrasive article, the method comprising (a) providing a substrate having a first major surface, (b) applying an adhesive layer comprising a moisture-curable hot melt adhesive comprising a polymer having hydrolysable or condensable silyl groups to the first major surface of the substrate, the hot-melt adhesive being in a molten or semi-molten state, (c) depositing abrasive particles on the adhesive layer, and (d) curing the hot-melt adhesive.
