Abstract: Described herein is a method for treatment of a metallic surface, including the step of (A) contacting the metallic surface with a first aqueous composition, and a subsequent step of (B) contacting the metallic surface subsequent to step (A) with a second aqueous composition. Also described herein is a kit-of-parts including the first and second aqueous composition and a kit-of-parts including master-batches of the first and second aqueous compostions. Also described is a method of using the kit-of-parts for treating a metallic surface and substrates including the thus treated metallic surfaces.

Abstract: The instant invention concerns the use of at least one polymer P obtained by radical copolymerization of a mixture of (i) acrylic acid; (ii) methacrylic acid; and (iii) at least one 2-hydroxyethyl methacrylate phosphate for treating a metallic surface intended to be adhesive-bonded to another surface, in order to impart a resistance to the adhesive failure to the resulting bonding.

Abstract: Provided are polymers obtained by radical copolymerization of a mixture of (1) acrylic acid; (2) methacrylic acid; and (3) at least one allylcatechol selected from 4-allylbenzene-1,2-diol, 3-allylbenzene-1,2-diol and mixtures thereof. The polymers are especially useful for treating a metallic surface intended to be coated by a paint, a varnish or an adhesive. Also provided are methods of coatings making use of this polymer P, compositions comprising the polymer P and useful for these methods, and the obtained coated materials.
