Abstract
An adhesion promoting composition and a process for treating metal surfaces with the adhesion promoting composition is described. The adhesion promoting composition comprises an oxidizer, an acid, a corrosion inhibitor, a source of halide ions and a material selected from a mercapto propane sulfonate, mercapto propane sulfonic acid, and bis-sodium sulfopropyl disulfide. The adhesion promoting composition increases the adhesion of polymeric materials to the metal surfaces and also provides increased acid resistance.
