Use of an oil composition for temporary treatment of metal surfaces

摘要

The invention concerns the use of an oil composition for temporarily protecting and lubricating metal surfaces, characterised in that said composition contains: at least 30% of at least a saturated or unsaturated C_≦18 fatty acid triglyceride (Compound A); 5 to 30% of at least a C_≦18 fatty acid triglyceride with oleic acid content of at least 60 wt. % (Compound B); 5 to 30% of at least an ester derived from condensation of a C₁-C₁₂, preferably, C₁-C₂ aliphatic alcohol, with a C_≦18 fatty acid (Compound C); and optionally 5 to 20% of at least an amide derived from condensation of a C≦18 ?fatty acid, and a C₂-C₆ mono- di- or tri-alkanolamine (Compound D). The invention also concerns a corresponding oil composition.
