    • Disclosed is an easily handleable composition for metal surface treatment which enables to achieve foundation surface concealment, coating adhesion and corrosion resistance equal to or higher than those obtained by the conventional metal surface treatment compositions. This composition for metal surface treatment places no burden on the environment. Also disclosed are a method for treating the surface of a metal material wherein such a composition for metal surface treatment is used, and a metal material treated by such a metal surface treatment method. Specifically disclosed is a metal surface treatment composition used for a treatment of a metal surface, which composition contains a zirconium compound and/or titanium compound substantially not containing fluorine, and an inorganic acid and/or a salt thereof. This metal surface treatment composition has a pH of not less than 1.5 but not more than 6.5. ® KIPO & WIPO 2009
    • 公开了用于金属表面处理的易于处理的组合物,其能够实现等于或高于通过常规金属表面处理组合物获得的基础表面隐蔽性,涂层粘附性和耐腐蚀性。 这种金属表面处理用组合物不会对环境造成负担。 还公开了一种处理金属材料的表面的方法,其中使用了这种用于金属表面处理的组合物以及通过这种金属表面处理方法处理的金属材料。 具体公开了用于处理金属表面的金属表面处理组合物,该组合物含有基本上不含氟的锆化合物和/或钛化合物,以及无机酸和/或其盐。 该金属表面处理组合物的pH值不低于1.5但不大于6.5。 ®KIPO&WIPO 2009
