Abstract
A corrosion protection composition that is advantageously unobjectionable from a health risk point of view and not easily flammable, for the economic production of anticorrosion coatings on metal workpieces, in particular, workpieces made of cast iron or steel, for the period of their storage and transport until the workpieces are installed, is composed of a solution of a mineral wax mixture in a liquid monocarboxylic acid ester. The composition includes from about 5 to about 10 parts by weight of a mineral wax mixture which has a molecular weight ranging between about 400 and about 600, and from about 70 to about 85 parts by weight of at least one liquid monocarboxylic acid ester which has a boiling point above 340.degree. C., and, optionally, additives such as antioxidants, antiozonants, antiaging agents, corrosion inhibitors, light stabilizers, and/or wetting agents. The corrosion protection composition, when heated, forms a clear, low-viscosity solution and, after being applied to the workpiece and cooled, forms a coating having viscous consistency which ranges from salve-like to pasty. The coatings are well suited to provide corrosion protection for, for example, piston rings or other sealing rings for internal-combustion engines.
