Abstract: A coated abrasive article comprises a backing having first and second opposed major surfaces, a make layer disposed on at least a portion of the first major surface and bonding abrasive particles to the backing, a size layer overlaid on at least a portion of the make layer and the abrasive particles, and a supersize layer disposed on the size layer. The supersize layer comprises an at least partially cured water-based epoxy resin and an organic polymeric rheology modifier, and wherein the amount of the at least partially cured epoxy resin comprises from 75 to 99.99 weight percent of the combined weight of the at least partially cured epoxy resin and the organic polymeric rheology modifier. A method of making the coated abrasive article is also disclosed.

Abstract: An abrasive article comprises abrasive particles adhered to a substrate by a binder material. The binder material comprises an at least partially cured resole phenolic resin and an organic polymeric rheology modifier. The amount of the at least partially cured resole phenolic resin comprises 99.01 to 99.98 weight percent of the combined weight of the at least partially cured resole phenolic resin and the organic polymeric rheology modifier. Methods of making the abrasive article are also disclosed.
