    摘要： A coated abrasive article comprises a backing, a first binder on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable preferably, melt-processable resin containing an epoxy resin, an ethylene-vinyl acetate copolymer, and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The above binder precursors of the invention are preferably free of homopolymers and copolymers of olefinic monomers. In another aspect, the invention also describes an energy curable first binder precursor containing an epoxy resin, an ethylene-vinyl acetate copolymer, a polyfunctional acrylate component and a curing agent for crosslinking the epoxy resin that is cured to provide a crosslinked make coating. The invention also relates to a method of producing such coated abrasive articles and a surface-treated backing material.

    摘要： The invention relates to a pressure-sensitive adhesive tape with improved room temperature handleability comprising an adhesive layer with at least one exposed surface and optionally a backing, wherein the pressure-sensitive adhesive layer comprises an epoxy/polyester based pressure sensitive adhesive which is crosslinkable upon exposure to actinic or e-beam irradiation and optionally heat, and comprises (i) 30-80% by weight of a polyester component comprising one or more amorphous polyesters compounds, (ii) 20-70% by weight of an epoxy component comprising one or more epoxy resins and/or monomers, (iii) 0-50% by weight of a hydroxyl-functional component containing one or more hydroxyl-containing compounds having a hydroxyl functionality of at least 1, and (iv) an effective amount of a photoinitiator component for crosslinking the pressure-sensitive adhesive, whereby the weight percentages refer to the total mass of components (i)-(iv) and add up to 100 wt. %, and which exhibits a holding power of at least 5 min.
