Antiloading compositions and methods of selecting same for use in abrasive products

摘要

Disclosed is an antiloading composition including a first organic compound which has a water contact angle criterion that is less than a water contact angle for zinc stearate. The first compound also satisfies at least one condition selected from the group consisting of a melting point Tmelt greater than about 40 DEG C, a coefficient of friction F less than about 0.4, and an antiloading criterion P greater than about 0.2. Another embodiment includes a second organic compound, having a different water contact angle from that of the first organic compound. The first and the second organic compound may be selected from the group consisting of sodium lauryl sulfate, sodium decyl sulfate, sodium octyl sulfate, sodium lauroyl sarcosinate, lauramidopropyl betaine, and sodium lauryl sulfoacetate. The composition has a particular water contact angle Wop that is determined, at least in part, by the independent Wog of each compound and the proportion of each compound in the composition. Also disclosed is an abrasive product including the antiloading composition, and a method of grinding a substrate that includes employing effective amount of an antiloading composition. Further disclosed is a method of selecting an antiloading compound.
