摘要
A process is described for increasing the adhesion of organic coatings to metal surfaces, particularly aluminum and aluminum alloys. The process involves the utilization of an adhesion promoting composition in treating the metal surface prior to application of the organic coating. The adhesion promoting composition comprises a nitro sulfonic acid. A chromating step is optionally employed.
