Abstract: A wear-resistant composition which includes a polymeric hot-melt binder system which includes at least one wear-resistant additive which includes diamond particles dispersed therein. A surface covering includes a base layer, a wear-resistant layer, and optionally a topcoat layer. The wear-resistant layer is laminated to the base layer. The wear-resistant layer may be formed by dispersing a plurality of wear-resistant additive particles, which include diamonds, into a liquid to form a stable liquid dispersion, blending the stable liquid dispersion into a polymeric resin to form a mixture, and extruding the mixture to form the wear layer.

Abstract: A method of forming a layered polishing pad is disclosed. The method includes double-laminating a subpad on opposing sides with respective adhesive layers and bonding a polishing pad top layer to the subpad via the upper adhesive layer. The polishing pad optionally includes a window. Because the subpad is double-laminated, an opening can be formed through both the top and bottom adhesive layers as well as the subpad. Thus, when bonded to a top polishing pad layer having a window, the result is a layered polishing pad with a through optical path that does not include an adhesive layer.
