摘要： A coated abrasive is disclosed that has been oversized with an anti-loading amount of a quaternary ammonium anti-static compound, comprising from about 15 to about 35 carbon atoms and a molecular weight not less than about 300, have been found to have a combination of anti-static, lubricity and anti-loading characteristics which provide improved abrading efficiency and longer abrading life.
