Abstract
Bonded abrasive compositions, articles incorporating same, and methods of making the compositions and articles are presented, the compositions comprising abrasive particles dispersed throughout and adhered within an elastomeric polyurea matrix. The polyurea matrix is formed from the polymerization reaction product of a polyfunctional amine and an isocyanate. The compositions exhibit excellent smear- and wear-resistance, and may be attached to a variety of backings. One preferred backing is integrally molded to the bonded abrasive composition.
