Abstract (en)

[origin: WO9721793A1] A method for preparing sheet metal for stamping and/or protecting it from corrosion by applying an aqueous solution of polyethoxylates of one or more lanolin derivatives, drying the surface to leave a dry deposit, and performing at least one oiling step on the dry deposit. In particular, the method enables stamping operations to be simplified, as even after prolonged storage, no fresh oiling of the treated sheet is required immediately prior to stamping.
