  • the anticorrosion performances of the samples are determined with the salt spray test.
  • the coated steel sheets are subjected to the salt spray test, carried out according to Standard NF X 41-002.
  • This test consists of spraying of a 5% by weight aqueous solution of NaCl, kept at a temperature of 35° C., in the form of a mist.
  • the sheets are regularly examined at different stages (at 24 hours, 72 hours, 144 hours and 150 hours) of exposure to the salt spray.
  • the presence of formed zinc salts is evaluated visually according to the following scale:
  • the resistance of the coated sheets to a solvent like methyl ethyl ketone is evaluated.
  • the degree of adherence of the protective coating to the surface of the metal substrate is determined as follows, according to Standard ISO 2409:
  • This test consists of deformation to 90% break of the coated substrate. This deformation is done on the back of the coated substrate.
  • Three galvanized steel sheets are degreased by immersion for 5 to 10 seconds in a bath containing 3.75% by weight of Chemetall Parco 305E®, relative to the total weight of the bath.
  • the pH of the bath is 13 to 14 and the temperature 50° C. to 60° C.
  • the sheets are then rinsed with cold demineralized water, then dried in a drying cabinet at 125° C. for 4 minutes.
  • the degreased, rinsed and dried sheets are then subjected to activation treatment by immersion in a bath of composition AFZ1 for one minute.
  • the plates are then dried in a drying cabinet for 5 minutes at 125° C.
  • the primer composition 1 is then applied, thus forming a moist primer film on the surface of the sheets about 10-12 ⁇ m thick.
  • the sheets coated with moist primer film are subjected to heat treatment (“flash off”) for 2 minute at 125° C., then crosslinking via radiation with UV radiation.
  • a crosslinked coating with a thickness of about 5-6 ⁇ m is obtained.
  • the salt spray test is conducted on the sheets, along with the adherence test, the solvent resistance test and the “ERICHSEN” test.
  • the coated sheets are then subjected to finishing treatment.
  • finishing treatment consists of applying a finishing composition of the polyester/melamine type, conventionally used in the paint industry.
  • This finishing composition is applied by means of a laboratory rule, then crosslinked by firing at 240° C. for 30 s.
  • the salt spray test is carried out on the sheets so coated (only before application of the finishing coat), along with the adherence test, the solvent resistance test and the “ERICHSEN” test.
  • FIG. 4 shows that at the deformation site, there is no longer any coating for the sheet of comparative example 1, both for the upper part (with finishing coating), or for the lower part of the sheet (without finishing coating). On the other hand, in the case of example 1, the coating persists (for the lower part and upper part with the finishing coat).
  • activation treatment with fluorozirconic acid improves the adherence of the protective coating to the metal substrate.
  • Galvanized steel sheets are degreased by immersion for 5 seconds in a bath containing 3.25% by weight of Chemetall Parco 305E®, relative to the total weight of the bath.
  • the pH of the bath is 13 to 14 and the temperature 50° C.
  • the sheets are then rinsed with cold demineralized water, then dried at 125° C. for 4 minutes.
  • the degreased, rinsed and dried sheets are then subjected to activation treatment by immersion in a bath of composition AFZ1 for 1 minute.
  • the plates are then dried in a drying cabinet for five minutes at 125° C.
  • primer composition 2 is then applied, thus forming a primer film on the surface of the sheet, having a thickness of about 10-12 ⁇ m.
  • the sheets so coated with primer film are then subjected to heat treatment (“flash off”) for 2 minutes at 125° C., then crosslinking by irradiation with UV radiation (one pass at 10 m/min under two emitters of the RPC 80 W type under nitrogen).
  • the salt spray test, adherence test (“ruling”), the solvent resistance test (A/R MEK) and the “ERICHSEN” of deformation resistance are then carried out on the sheets so coated.
  • coated sheets with the primer film are then finally subjected to the same finishing treatment as in example 1.
  • the same protective coating as described in example 2 is applied to the galvanized steel sheets, proceeding in the same manner as described in example 2, except for the immersion step in the bath of composition AFZ1 based on fluorozirconic acid, which was omitted.
  • FIGS. 5 and 6 Comparison of the results of the salt spray tests of examples 2 and C2 is illustrated by FIGS. 5 and 6 . These figures show that the sheets of comparative example 2 have white longitudinal traces (called “bleeding”) after 140 hours in a salt spray, whereas the sheets of example 2 do not show them. The resistance to salt spray is therefore better when the sheets have been subjected to activation treatment with fluorozirconic acid prior to deposition of the primer composition.
  • Galvanized steel sheets are degreased by immersion for 5 seconds in a bath containing 3.75% by weight of Chemetall Parco 305E®, relative to the total weight of the bath.
  • the pH of the bath is 13 to 14 and the temperature 50° C.
  • the sheets are then rinsed with cold demineralized water, then dried at 125° C. for 4 minutes.
  • the degreased, rinsed and dried sheets are then subjected to activation treatment by immersion in a bath of composition AFZ3 for 2 minutes.
  • the sheets are then dried in a drying cabinet (“flash off”) for 2 minutes at 1 25° C.
  • the primer composition 1 is then applied, thus forming on the surface of the sheet a wet primer film, having a thickness of about 10-12 ⁇ m.
  • the sheets coated with primer are then subjected to the same finishing treatment as for example 1.
  • FIG. 7 shows the state of the coated sheets of example 3, after having been subjected to the salt spray test for 150 hours.
  • the same protective coating as described in example 3 is applied to the galvanized steel sheets, proceeding in the same manner as described in example 3, except for the immersion step in the bath of composition AFZ3 based on fluorozirconic acid, nitric acid and cationic resin, which was omitted.
  • FIG. 8 shows the state of the coated sheets of example 3, after having been subjected to the salt spray test for 150 hours.
  • FIGS. 7 and 9 show that the sheets of example 3 have significantly fewer white traces (“bleeding”) than those of comparative example 3, indicating that prior activation treatment imparts better corrosion protection to the primer film.
  • Electrogalvanized steel sheets are degreased by immersion for 5 seconds in a bath containing 3.75% by weight of Chemetall Parco 305E, relative to the total weight of the bath.
  • the pH is 13 to 14, and the bath temperature 50° C.
  • electrogalvanized steel sheets in the same manner as desribed in the preceding examples, are rinsed with cold demineralized water, then dried at 125° C. for 4 minutes.
  • the degreased, rinsed and dried sheets are then subjected to activation treatment by immersion in the bath at ambient temperature of composition AFZ2 for one minute.
  • the sheets are then dried in a drying cabinet (“flash off”) for 2 minutes at 125° C.
  • the primer composition 1 is then applied, thus a film forming on the surface of the sheet with a wet thickness of about 10-12 ⁇ m.
  • the sheets coated with primer are then subjected to the same finishing treatment as for example 1.
  • Electrogalvanized steel sheets are degreased by immersion for 5 seconds in a bath containing 3.75% by weight of Chemetall Parco 305E®, relative to the total weight of the bath.
  • the pH is 13 to 14, and the temperature of the bath is 50° C.
  • the electrogalvanized steel sheets in the same manner as the preceding examples, are rinsed with cold demineralized water, then dried at 125° C. for 4 minutes.
  • the degreased, rinsed and dried sheets are then subjected to activation treatment by application with a roll coater in a bath at ambient temperature of composition AFZ2 for one minute.
  • the sheets are then dried in a drying cabinet (“flash off”) for 2 minutes at 125° C.
  • the following primer composition is then applied, thus forming a wet primer film on the surface of the sheet, having a thickness of about 6 ⁇ m: Rom UV: SM1530/140B Duroxyne VZX6127 18 Water 4.3 Anti-foaming agent byk 028 0.1 TEA 1 Schieldex C303 3.6 K wite ktc 720 1.6 Ucecoat DW7770 72 Byk 346 0.3 Irgacure 500 1 Schewgo pur 0.4
  • the sheets so coated then receive a film with 20 ⁇ m dry thickness of the anticorrosion primer W780-9735 from PPG by cathode electrodeposition.
  • a corrosion test VDA 621-41, an alkaline degreasing test and an Erichsen test are then carried out on the sheets.
  • the same protective coating as described in example 5 is applied to the electrogalvanized steel sheets, proceeding in the same manner as described in example 5, except for the immersion step in the bath of composition AFZ2 based on fluorozirconic acid, which was omitted.
