The processing method of the post-treatment agent of the steel strip or steel sheet metal coating is coated, and the steel band or steel sheet metal coating is coated

摘要

The present invention provides a method for processing a steel band or steel sheet is coated with the metal coating in the post-treatment agent, after-treatment agent, it includes at least one polyalkylene glycol, the solution on the surface of the metal coating it is applied as a. According to the present invention, to achieve the adhesion and improved infiltration of the coating film is lowered as much as possible the friction coefficient of the coated surface at the same time, it provides a good processability of the coated steel strip or steel sheet To, post-treatment agent includes a fluorescent antioxidant in addition to the polyalkylene glycol. The present invention further provides the surface, the steel band or steel sheet metal coating is coated with a thin film of a post-treatment agent containing a polyalkylene glycol and fluorescent antioxidants also relates in particular tinplate.
