    Abstract: Method for applying corrosion protection layer on a metallic surface comprises treating the surface with a formulation containing at least one binding agent, a pigment and/or a filler and a corrosion protecting agent, which is at least one thioamide group containing compounds. Method for applying corrosion protection layer on a metallic surface comprises treating the surface with a formulation containing at least one binding agent, a pigment and/or a filler and a corrosion protecting agent, which is at least one thioamide group of formula -C(S)NR 1>R 2> containing compounds such as thioamide compound (D1) of formula R 4> n-R 3>-C(S)NR 1>R 2> or thioamide (D2) with at least two thioamide group. n : 1-5; R 1>, R 2>H or optionally substituted 1-20C alkyl; R 3>(n+1)-valenced 1-30C hydrocarbon; and R 4>functional group. Independent claims are included for: (1) a method for applying an integrated pretreating layer on metallic surface comprising treating the metallic surface with a crosslinkable preparation, containing a binding agent, a crosslinkable component, where the crosslinkable group is bounded with the binding agent and/or additionally a crosslinker is used, a pigment and/or filler, a corrosion protecting agent and optionally a solute, and crosslinking the applied layer, where the amount of the binding agent is 20-70 wt.%, filler contains 20-70 wt.% of at least one inorganic fine particulate fillers with an average particle size of less than 10 mu m, and the corrosion protecting agent contains 0.25-10 wt.% of thioamide group containing compounds, where the wt.% relate to the sum of all components except the solute; (2) a polymer comprising at least two terminally and/or laterally positioned thioamide group of formula -C(S)NR 1>R 2>; (3) integrated pretreating layer on a metallic surface of steel, zinc or its alloy or aluminum or its alloy obtained by the method; (4) metallic surface comprising the integrated pretreating layer; (5) a strip metal from steel containing a coating from zinc or its alloy comprising the surface; (6) a preparation, for applying corrosion protection layer on metallic surface, comprising at least one binding agent, a pigment and/or a filler and a corrosion protecting agent, which is at least one thioamide group of formula -C(S)NR 1>R 2> containing compounds such as thioamide compound (D1) of formula R 4> n-R 3>-C(S)NR 1>R 2> or thioamide (D2) with at least two thioamide group; and (7) a preparation, for applying an integrated pretreating layer on metallic surface, comprising a binding agent, a crosslinkable component, where the crosslinkable group is bounded with the binding agent and/or additionally a crosslinker is used, a pigment and/or filler, a corrosion protecting agent and optionally a solute, where the amount of the binding agent is 20-70 wt.%, filler contains 20-70 wt.% of at least one inorganic fine particulate fillers with an average particle size of less than 10 mu m, and the corrosion protecting agent contains 0.25-10 wt.% of thioamide group containing compounds, where the wt.% relate to the sum of all components except the solute.
