METHOD FOR MAKING AN ABRASIVE ARTICLE AND ABRASIVE ARTICLES THEREOF

摘要

Reaction injection molding is utilized as a method for making an abrasive article (10) that includes supplying an effective amount of abrasive particles (26) to at least a portion of an abrasive article mold and supplying a binder precursor matrix (28) that includes at least two interactive components to the abrasive article mold. When the binder precursor matrix (28) is cured, the abrasive particles (26) are secured within a binder formed from the binder precursor matrix. An abrasive article (10) includes a plurality of bristles (18) including an increased amount of abrasive particles, wherein a ratio of binder (28) to abrasive particles (26) is at least about 1:3 by weight.
