US Patent:

20010049911, Dec 13, 2001
Filed:

Mar 16, 2001
Appl. No.:

09/810857
Inventors:

Gwo Swei - East Amherst NY, US
Sylvain Petigny - Tonawanda NY, US
International Classification:

C09K003/14
US Classification:

051/307000, 051/308000
Abstract:

Fine abrasive powders can be made more free-flowing and better adapted to UP deposition in the production of coated abrasives by the control of the volume resistivity of the powder to a level that is not greater than 10ohms.cm by incorporation of a silica powder.
