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.
Claims44
An abrasive article comprising:
- a backing having a first major surface and a second major surface;
- a plurality of abrasive particles;
- at least one bond system formed from a composition comprising a binder precursor and about 15% by weight or less of a wax-containing modifier wherein the bond system adheres the plurality of abrasive particles to the first major surface of the backing.
An abrasive article comprising:
- a backing having a first major surface and a second major surface;
- a plurality of abrasive particles;
- a make coat bond system formed from a first binder precursor, wherein the make coat bond system bonds the plurality of abrasive particles to the first major surface of the backing;
- a size coat bond system formed from a composition comprising a second binder precursor and about 15% by weight or less of a wax-containing modifier, wherein the size coat bond system forms at least a portion of a peripheral surface of the abrasive article.
