Abstract
Abstract A wax composition which can be used as a protective coating, a release agent, or the like, and applied to articles by spraying or brushing the composition onto the article or by dipping the article in the composition or the like. The wax composition comprises a homogeneous combination of a wax and a thermoplastic resin and/or a fatty amide in solution. The solution in a specific embodiment contains a wax, a thermoplastic resin, a fatty amide, an aromatic solvent, an aliphatic petroleum solvent, and a chlorinated solvent.
