Abrasive grain with improved projectability for production of coated abrasives having a first surface coating on the grain comprising a conductive material and a second surface coating over the first comprising a silicon-containing compound selected from the group consisting of silicates, aminosilanes and mixtures thereof.
A process for the production of abrasive grain with improved projectability for production of coated abrasives which comprises:
- a) providing an abrasive grain selected from the group consisting of alumina and fused alumina/zirconia;
- b) applying a first surface coating to said grain comprising a conductive material dispersed in a carrier;
- c) applying a second coating over the first surface coating which second coating comprises a silicon-containing compound selected from the group consisting of silicates, organosilanes and mixtures thereof;
- and
- d) drying the coated grain.
