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 that includes supplying an effective amount of abrasive particles to at least a portion of an abrasive article mold and supplying a binder precursor matrix that includes at least two interactive components to the abrasive article mold. When the binder precursor matrix is cured, the abrasive particles are secured within a binder formed from the binder precursor matrix. An abrasive article includes a plurality of bristles including an increased amount of abrasive particles, wherein a ratio of binder to abrasive particles is at least about 1:3 by weight.
