Publication number: 20070173180Abstract: An antiloading composition includes a first organic compound. The compound 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° C., a coefficient of friction F less than about 0.3, and an antiloading criterion P greater than about 0.3. Another embodiment includes a second organic compound, having a different water contact angle from that of the first organic compound. The composition has a particular water contact angle W°p that is determined, at least in part, by the independent W°g of each compound and the proportion of each compound in the composition.
