                      Abstract:To  solve  the  problem  that  the  protective  coating  on  the  automobile  engine
                 cylinder block was easy to be destroyed and peeled off by the ultrasonic-chemical cleaning
                 process,a  high-performance  waterborne  one-component  dip-coating  was  developed  and  its
                 application effect was studied in this paper. The effects of film former,wetting agent,drier and

                 chemical  cleaning  resistance  of  the  paint  film  were  discussed. The  results  showed  that  the
