Abstract

A surface-modified abrasive grain includes an abrasive grain as a substrate, and a film on the abrasive grain that includes a relatively hydrophilic silane component and a relatively hydrophobic silane component. The film can be a single film layer or multiple film layers, wherein a film layer most proximal to the abrasive grain has a predominately hydrophilic silane component, and a film layer more distal to the abrasive grain includes predominately a relatively hydrophobic silane component. Coated abrasive products and bonded abrasive products include the surface-modified abrasive grains.
