Beschreibung
Zusammenfassung:	To provide a method for coating a metal surface, capable of avoiding a pinhole on a zinc containing metal surface.SOLUTION: In the use of a silane additive in an aqueous cleaning composition in an aqueous rinse or/and an aqueous active composition, the amount of the silane additive obtained by calculating a content of at least one kind of silane, silanol or/and siloxane in at least one of the aqueous compositions for each silane is within a range of 0.001-5 g/L.SELECTED DRAWING: Figure 1 【課題】亜鉛含有金属表面上でピンホールを避けるための、金属表面の被覆方法の提供。【解決手段】水性洗浄組成物中での、水性すすぎ液中での又は／及び水性活性化組成物中でのシラン添加物の使用であって、シラン添加物量は、前記水性組成物の少なくとも１つにおけるそれぞれ少なくとも１種のシラン、シラノール又は／及びシロキサンの含分が、それぞれのシランについて算出して０．００１〜５ｇ／Ｌの範囲内とする。【選択図】図１
