The principal use of wax in paint technology is as an ingredient of polishes for floors, furniture, and automobiles, and in coatings for paper. Many natural waxes of animal, vegetable, and mineral origin are used for these purposes. Camauba, ouricuri, candelilla, beeswax, paraffin, microcrystalline, and oxidized microcrystalline predominate. The natural waxes, except the hydrocarbons of which paraffin is an example, consist of esters of the higher fatty acids, such as cerotic (C25H61COOH), and the higher monohydroxy alcohols, such as myricyl (C30H61OH). In addition there are present free fatty acids, alcohols, and small percentages of hydrocarbons. Table 8.4-1 gives the important constants of many of the natural waxes.
