- the pretreated test panels were used to further test the effect coated with an electrocoat.
- the rust at the Ritz was used as a measure of the adhesion of the paints certainly.
- a 0.1 mm wider was made on the steel sheets Longitudinal section, on the sheets with a phosphate conversion layer a 0.1 mm wide cross cut carved into the paintwork, that reached down to the sheet metal surface.
- the painted steel sheets were then 15 days in the salt spray test (40 ° C, 5% NaCl solution: DIN 50 021) for corrosion resistance checked.
- the painted steel sheets with a phosphate conversion layer were tested in the salt water soak test. For this the test plate was heated for 10 days in a 5% solution heated to 55 ° C NaCl solution immersed.
- Degreased body steel sheet (e.g. St 1405) was as above specified in aqueous polyvinylamine solutions of various concentrations immersed, treated and electrocoated.
- a manganese-modified low-zinc-phosphated coating on both sides (Spray process) and then rinsed with water Steel sheet (BONDER® 26 W OC) was poured into aqueous as indicated above Immersed polyvinylamine solutions of various concentrations and processed further.
- the extent of the rust is reduced by the adhesion-promoting Polymer layer in the samples with a phosphate conversion layer by two to three times.
- the method according to the invention completely prevents rust formation.
- the entire appearance of the paint surface also shows through the method according to the invention compared to a significant improvement the state of the art. While the lacquered surfaces of the reference samples show strong blistering, the paint surface is on the metal surface modified with aqueous polyvinylamine solution perfect.

Description
190 x 105 x 0,75 mm große Prüfbleche wurden jeweils 1 Minute in wäßrige Polyvinylaminlösungen (K-Wert 30) getaucht. Die Konzentrationen der Polymerlösungen waren 0,01; 0,1; 1 und 2 %. Die Badtemperatur betrug jeweils 23° und 50°C, s. Tabelle. Nach dem Trocknen an Luft wurden die Bleche noch 5 Sekunden in vollentsalztes Wasser getaucht und erneut an Luft getrocknet.
Der Korrosionstest zeigt an den Beispielen 1 bis 4 deutlich die Vorteile des erfindungsgemäßen Verfahrens im Vergleich zu den Referenzproben nach dem Stand der Technik.
