Abstract: An abrasive article is provided which includes a peripheral surface formed comprising a grinding aid. The grinding aid is formed from a mixture including an acid and at least one of an inorganic metal phosphate salt or an inorganic metal sulfate salt. The acid is preferably selected so that the mixture forms a film. The abrasive article preferably has sharp abrasive particles. The inventive abrasive article improves grinding efficacy, particularly in titanium grinding processes, as compared to abrasive articles that are substantially devoid of a grinding aid of the present invention. Also provided is a method for making an abrasive article and a method of abrading a surface with an abrasive article.

Abstract: An abrasive article, for example, a coated, bonded, or nonwoven abrasive article comprising a binder, a plurality of abrasive particles, and an antiloading component.

Abstract: An abrasive article is provided that includes at least one binder system formed from a polymeric additive and a thermosetting resin. The polymeric additive includes a polymeric backbone having substituents attached thereto, wherein the substituents include at least one urethane linked nitrogen bonded side chain having about 5 carbon atoms or more and a terminal methyl group and at least one oxygen linked water solubilizing group. An abrasive article that includes the binder system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a binder system formed from a composition containing substantially no polymeric additive.

Abstract: An abrasive article is provided that includes a bond system formed from a binder precursor and about 15% by weight or less of a wax-containing modifier. An abrasive article that includes the bond system exhibits an increase of workpiece surface abraded in a Woodsanding Normal Force Test as compared to an abrasive article including a bond system formed from a composition containing substantially no wax-containing modifier.

Abstract: A coated abrasive article comprised of a backing having a layer of grains adherently bonded thereto by a binding material, wherein the layer of grains comprises abrasive grains and nonabrasive composite grains, and the nonabrasive composite grains comprise inorganic nonabrasive particles bonded together by a binder selected from the group consisting of a metal salt of fatty acid, colloidal silica, and combinations thereof. The abrasive article has an unexpected abrading efficiency, performing equal to, or superior to, a coated abrasive article containing only abrasive grains. The invention also relates to a bonded abrasive article comprising the abrasive grains and nonabrasive composite grains adhered together.

Abstract: An abrasive article, and methods of making and using same, comprising an inorganic phosphate selected from the group consisting of an alkali metal metaphosphate, an alkaline earth metal metaphosphate, and a Group IIIA metal orthophosphate; the inorganic phosphate may be present in a peripheral coating layer of a coated abrasive article, or an abrasive slurry coating in a uniform thickness, or a structured abrasive article.

Abstract: Abrasive articles comprising a plurality of abrasive particles, a combination of potassium tetrafluoroborate and a halogenated polymer, and a binder to which the plurality of abrasive particles are adhered, and methods of making and using the abrasive articles.

Abstract: A method for preparing a coated abrasive article wherein the a plurality of abrasive grains are applied to a make coat such that the abrasive grains are substantially a mono-layer. The make coat precursor is a pressure-sensitive adhesive-like or pressure-sensitive adhesive. The make coat precursor is partially cured to approximate a pressure-sensitive adhesive-like layer or when fully cured is a pressure-sensitive adhesive. The make coat precursor has sufficient "tack" to hold the abrasive grains during the application and curing of the size coat, resulting in a substantially monolayer of abrasive grains.

Abstract: Coatable mixtures including erodable filler agglomerates, and abrasive articles into which they may be incorporated are presented, the agglomerates comprising a plurality of individual grains of water insoluble filler agglomerated by an agglomerating agent which includes water soluble filler and a binder. A preferred water soluble filler is Al.sub.2 (SO.sub.4).sub.3.14-18H.sub.2 O, a preferred water insoluble filler is Na.sub.3 AlF.sub.6 (cryolite), while a preferred binder is a phenolic resin. Methods of making coatable mixtures including erodable filler agglomerates are also presented.
