ABSTRACT:
Urea particles uniformly coated with zinc oxide having excellent adherence and uniformity of the zinc oxide coating are obtained by using a zinc oxide composition characterized by having a purity of 90 to 99% zinc oxide and a uniform particle size of at least 90% smaller than 12 microns and at least 95% smaller than 37 microns. Outstanding coatings are obtained if the zinc oxide composition additionally contains traces of carbon, iron oxide, magnesium oxide, or calcium oxide. High zinc-content coatings of excellent uniformity and adherence may be obtained with these coating compositions.
