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.

1-8. (canceled)
A method of forming a surface-modified abrasive grain, comprising the steps of:
- a) combining relatively hydrophilic and relatively hydrophobic silane components to form a mixture;
- b) combining the mixture with a solvent to form a silane solution;
- c) reacting at least a portion of the silane components to form a partially oligomerized silane solution;
- and
- d) blending the partially oligomerized silane solution with an abrasive grain component to form the surface-modified abrasive grain.
