FIELD: technological processes.
SUBSTANCE: invention relates to a method for treating a steel band or steel plate provided with a metal coating with an after-treatment agent. After-treatment agent comprises at least one polyalkylene glycol and a fluorescent antioxidant, which is fluorescent when excited with light during fluorescent spectroscopy. Agent is applied in form of a liquid solution on surface of metal coating. Further, invention relates to steel band or steel plate with metal coating, particularly to white tin, which on surface of metal coating comprise a thin layer of said after-treatment agent.
EFFECT: invention provides better wetting with paint material and better adhesion of paint material and simultaneously as low coefficient of friction surface as possible, as well as good processibility of steel band or steel plate with coating.
