US Patent:

7015268, Mar 21, 2006

Filed:

Jan 16, 2002

Appl. No.:

10/050662

Inventors:

Kenneth E. Manwiller - New Ipswich NH, US
Anne B. Hardy - Acton MA, US

Assignee:

Saint-Gobain Abrasives Technology Company - Worcester MA

International Classification:

C08K 3/34

US Classification:

524444, 524424, 524430

Abstract:

A microabrasive tool is formed from a slurry including liquid, abrasive grains, a bonding material, and a polymer—for example, gellan gum. The slurry is cast in a mold, and the polymer is ionically cross-linked. Cross-linking the polymer fixes the structure of the bonding material and the abrasive grains, wherein the abrasive grains are dispersed substantially uniformly within the bonding material. The ionically cross-linked structure of bonding material and abrasive grains can then be fired to form a microabrasive tool.
