  • Chemical post-treatment of selectively galvanized steel strip and sheet
    Patent number: 4708779
    Abstract: This invention is directed to a method of treating a selectively galvanized steel strip, such as one-side electrogalvanized sheet, to improve the appearance and paintability of the non-galvanized areas of said strip. The post chemical processing of the strip, which processing does not chemically attack the zink-coated areas of the strip, comprises the steps of applying to the strip a solution of an aqueous bifluoride salt, followed thereby by rinsing said strip with a dilute caustic solution.
