Method for ni-free phosphatizing of metal surfaces and composition for use in such a method |
| abstract |
The present invention relates to a method for treatment of at least one surface of a metal containing substrate comprising at least steps (1) and (3), namely contacting said surface with an aqueous acidic Ni-free composition (A) comprising at least zinc cations, manganese cations and phosphate anions to form a conversion coating on the surface (1) and contacting said formed coating with an aqueous Ni-free composition (B) comprising one or more linear polymers (P) containing at least vinyl phosphonic acid, (meth)acrylic acid and hydroxyethyl- and/or hydroxypropyl (meth)acrylate in form of their polymerized monomeric units, to said composition (B) as such, to a master batch to produce said composition (B), to a kit-of-parts comprising both compositions (A) and (B) as well as to a kit-of-parts comprising respective master batches to produce both compositions (A) and (B) as well as to a coated substrate obtainable by the inventive method. |
