Sorry for reply late. Right now for cleaning process, they use cleaner of Nippon for Degreasing and can't change because in Zn phosphate process, customer their them need to specify chemical of Nippon all process. So process for passivate aluminum need to join cleaner of Nippon because tank is not enough and not have area for add more tank.
Now sales just 2 products is epicene-AD3S and Dipsol-ALT 610 and if new testing OK, customer may be change type chemical to ST-650 and ST-495L
