Definitions
- the present invention relates to an anti-fouling treatment process for motor vehicles by depositing on the surface of said vehicles an organic anti-fouling polymer during a washing operation or during a rinsing operation.
- Washing a vehicle consists in removing the static film ("traffic film”) deposited on the bodywork.
- This film constitutes a greasy and particulate soiling, essentially coming from the gases emitted by the exhaust pipes of vehicles. This dirt is particularly difficult to remove, since it strongly adheres to the bodywork mainly by electrostatic effects.
- Combinations of cationic, nonionic and / or amphoteric surfactants have been developed to achieve effective cleaning; however, it has been found that it is extremely difficult to remove all of the static film, which poses a problem, especially for light-colored vehicles.
- the Applicant has found an anti-fouling treatment on the surface of vehicles making it possible to limit the adhesion of the static film to the bodywork and thus to facilitate its elimination.
- it is a method of antifouling treatment of vehicles, by deposition on the surface of said vehicles, during a washing or rinsing operation, of an organic antifouling polymer soluble or dispersible in the processing medium.
- the static film formed following the use of said vehicle is removed at the same time as said organic anti-fouling polymer deposited during treatment.

- the sheet is then dried with a hair dryer.
- the test is reproduced without a prior vaporization step of the polymer; only the soiling and washing step is carried out.
- Reflectance measurements (8 measurements are made at different locations on the sheet) at an angle of incidence of 60 °, are carried out - on the clean starting sheet:
