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.
Claims18
A method of making an abrasive article comprising:
- disposing a make layer precursor consisting essentially of a curable composition on a substrate, wherein the curable composition comprises a resole phenolic resin and an organic polymeric rheology modifier, wherein the organic polymeric rheology modifier comprises an alkali-swellable/soluble polymer, and, on a solids basis, wherein the amount of the resole phenolic resin comprises 99.01 to 99.98 weight percent of the combined weight of the resole phenolic resin and the organic polymeric rheology modifier;
- adhering abrasive particles to the curable composition;
- and
- at least partially curing the curable composition.
