Abstract

PURPOSE: To prevent the formation of white rust on the surface of galvanized steel sheet, by painting the galvanized steel sheet with rhodamine alone, or with a treating soln. contg. rhodamine.
CONSTITUTION: The surface of galvanized steel sheet made by hot dipping method, electroplating method etc. is painted with rhodamine alone or with compound soln. composed of rhodamine and one ore more members among a silicate compound such as colloidal silica, boric acid compound, phosphoric acid compound, OH-contg. compounds such as lignin, tannic acid, phytic acid, and polymeric compounds such as epoxy resin, polyimide resin by rolling method, immersion method, spray method, or electrodeposition method to form 0.1mgW2g/m2 film. The painted steel sheet is dried at need to form film on the galvanized steel sheet, hereby formation of white rust due to moisture is prevented.
