An improved Protective aqueous composition for temporary protection of metal surfaces and coated surfaces

摘要

The invention relates to a process for the temporary protection of metal and lacquered surfaces comprising applying thereto an aqueous emulsion containing a hydrocarbon wax or the oxidate thereof, optionally waxes based on montan wax and/or natural waxes, as well as a basic saponifying agent and emulsifiers. The wax films resulting from the emulsions are waterproof, however, they are easily removable-even after aging-without the use of a solvent being necessary, merely by a treatment with a water-steam mixture.
