According to one embodiment, a method of making an abrasive article is disclosed. The method can comprise: disposing a layer of a curable composition into a mold having a circular mold cavity with a central hub, wherein the circular mold cavity has an outer circumference and a rotational axis extending through the central hub, and wherein the curable composition is comprised of at least some magnetizable abrasive particles dispersed therein; and varying a magnetic field relative to the curable composition such that a majority of the magnetizable abrasive particles are at least one of oriented and aligned in a non-random manner relative to a surface of the mold; and at least partially curing the curable composition to provide the bonded abrasive article.

The present disclosure relates to an abrasive article. The abrasive article (10) includes a non-woven web (12). The non-woven web (12) includes a fiber or filament component (18). The non-woven web (12) further includes a first major surface (14) and a second major surface (16). A thickness of the non-woven web (12) is defined from the first major surface (14) to the second major surface (16). The abrasive article further includes a plurality of shaped abrasive particles (22) dispersed through at least a portion of the non-woven web (12). The abrasive article further includes a heat-activated water-forming inorganic component dispersed through the non-woven web (12).

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 from 75 to 99.99 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.

A method for treating an abrasive article includes applying a release agent dispersion onto at least one surface, which is provided for abrading, of the abrasive article in order to produce a cover layer. The release agent dispersion includes at least one anti-adhesion agent. The release agent dispersion further includes at least one film-forming agent.
