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.
