Abstract
The present invention provides abrasive articles having projections attached to a major surface thereof, and methods of making such articles. The articles include (1) a reaction product of components that include (a) an epoxy-functional material, (b) at least one of a cyclic anhydride or a diacid derived therefrom; and/or (2) a polymeric material preparable by combining at least (a) an epoxy-functional material, and (b) at least one of a cyclic anhydride or a diacid derived therefrom.
Claims35
An abrasive article comprising:
- a backing having a major surface;
- a plurality of projections attached to the major surface, wherein the projections are formed by use of a production tool;
- and
- a binder comprising a reaction product of components comprising (a) an epoxy-functional material, and (b) at least one of a non-polymeric cyclic anhydride or a diacid derived therefrom.
An abrasive article comprising:
- a backing having a major surface;
- a plurality of projections attached to the major surface, wherein the projections are formed by use of a production tool;
- and
- a binder preparable by combining components comprising at least (a) an epoxy-functional material, and (b) at least one of a non-polymeric cyclic anhydride or a diacid derived therefrom.
A method of making an abrasive article comprising:
- providing a production tool having a three-dimensional body with one or more cavities, at least a portion of the one or more cavities having therein a composition preparable by combining components comprising at least (a) an epoxy-functional material, and (b) at least one of a non-polymeric cyclic anhydride or a diacid derived therefrom, and wherein the production tool has a backing that has a major surface adjacent the one or more cavities;
- and
- at least partially curing at least a portion of the composition to form an abrasive article.
