ABSTRACT:
Contact of acid or alkaline cleaned aluminum surfaces, particularly cans, with a water based composition containing a combination of (i) ethoxylated phosphate esters, ions of aluminum, zirconium, iron, tin, and/or cerium, and (iii) a metal etching component gives the surface after drying lowered surface friction without loss of high quality printability and lacquer adhesion and removes any brown spotting on the cans that may have developed during the cleaning or post-cleaning rinses.
