Abstract
Mixtures of 50 to 99 percent hydrocarbon waxes and 1 to 50 percent of hydrocarbon soluble surfactants chosen from the group consisting of (a) primary and secondary alkyl amines in which the alkyl groups contain 16 to 30 carbon atoms, and (b) fatty acid amides of primary alkyl amines and (c) fatty acid esters of alkanols in which the alkyl groups of the acids, amines and alkanols contain 16 to 30 carbon atoms, or mixtures thereof, provide sealant coatings for sulfur coated urea which are superior moisture barriers and are non-blocking and thus do not require the addition of clay or other fine particle materials.
