Accordingly, they can of course also be marketed as aqueous concentrates with a solids content in the range from 15 to 50% by weight or in an application dilution of 5 to 15% by weight.
  • Another object of the invention relates to their use for the simultaneous cleaning and antistatic finishing of painted metal surfaces, in particular car bodies and body parts.
  • compositions 1 to 3 according to the invention and the comparative mixtures V1 to V3 were assessed with regard to their cleaning performance, the antistatic finish and the run-off behavior.
  • the cleaning ability was assessed in such a way that a red lacquered sheet (10 ⁇ 10 cm) was coated with 5 g of lubricating oil and then treated for 20 s with a 5% strength by weight aqueous solution of the test substances in the form of a sharp water jet (“kärchern”) The residue was then incinerated, weighed and compared to the amount of oil originally applied, ie the lower the value, the higher the performance.
  • the antistatic finish was determined using red-painted metal sheets via the path of conductivity. The higher the resistance found "The better the antistatic charge and the less the tendency to become contaminated by flying dust.
  • the drainage behavior was determined subjectively. (+++) stands for very rapid, (-) for slow drainage. The results are shown in the table 1 summarized.
