Abstract
Abstract A flowable abrasive composition comprising a polyboronorgano silicon compound and dispersed abrasive granules, said composition being modified with a gel formed from a metallic soap (8-22 carbon atoms) and a hydrocarbon oil. The composition is especially useful for honing, abrading, deburring or polishing surfaces, especially metallic surfaces.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
96 words
A method of abrading or polishing or honing or deburring a surface comprising flowing under pressure and at a high velocity through a restricted passage, a surface of which comprises said surface to be abraded, polished, honed or deburred, an abrasive composition comprising (1) a boron-dialkyl silicon-oxygen polymer, (2) a gel modifier formed from a metallic soap of a fatty carboxylic acid having 8 to 22 carbon atoms and a hydrocarbon oil and (3) abrasive grit particles dispersed in said compound and gel modifier, said high velocity being achieved by pressure drop across said restricted passage.
