摘要： A coated abrasive article comprises a backing, a first binder (i.e., a make coat) on the backing, and a plurality of abrasive particles in the first binder. The first binder precursor is an energy-curable melt-processable resin containing an epoxy resin, a polyester component, 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 porous cloth material.

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 present invention involves the use of powder coating methods to form coated abrasives. In one embodiment, the powder is in the form of a multiplicity of binder precursor particles comprising a radiation curable component. In other embodiments, the powder comprises at least one metal salt of a fatty acid and optionally an organic component that may be a thermoplastic macromolecule, a radiation curable component, and/or a thermally curable macromolecule. In either embodiment, the powder exists as a solid under the desired dry coating conditions, but is easily melted at relatively low temperatures and then solidified also at reasonably low processing temperatures. The principles of the present invention can be applied to form make coats, size coats, and/or supersize coats, as desired.

摘要： The present invention provides a composition for use in coated abrasives. The curable composition comprises a mixture of: i) from about 30 to about 60 weight percent of an oligomeric aminoplast resin having on average at least one pendant &agr;,&bgr;-unsaturated carbonyl group per oligomeric unit; ii) from about 70 to about 40 weight percent of a thermoplastic polyamide miscible in said aminoplast resin, the weight percents being based on the total resin content; and iii) a sufficient amount of a catalyst for the curable oligomeric aminoplast resin having on average at least one pendant &agr;,&bgr;-unsaturated carbonyl group per oligomeric unit, said catalyst being stable at a temperature of mixing of the components. The curable composition can either be in the form of a melt-processable solid or a molten mixture. The present invention also provides single and multilayered treated backing substrates used in coated abrasives.
