- the air is expediently extracted downwards.
- the venting zone can be operated under constant operating conditions or by varying individual or multiple operating parameters.
- the operating parameters can be varied in the form of a continuous or abrupt change over the entire length or one or more parts of the length of the venting zone.
- the venting zone can be divided into one or more, for example 1 to 3, zones which can be separated from one another by locks.
- the variation of the operating parameters during the ventilation is always within the limits specified by the invention for the ventilation process to be considered as a whole.
- the flash-off zone is divided into two zones, the bodies coated with water-based paint firstly in the first zone at low air temperatures, for example from 25 to 30 ° C., and then in the second zone at higher air temperatures, for example from 30 ventilated up to 45 ° C; the air throughput can be selected to be the same or different in both zones, for example, in the first zone lower than in the second, for example the flow velocity of the circulating air measured on the object in the second zone can be above 8 m / s.
- the average air throughput is within the limits specified by the invention.
- the water-based lacquer layers predried by flashing are overpainted with a conventional chemically crosslinking clear lacquer in a dry layer thickness of, for example, 30 to 100 ⁇ m and baked together with the latter at temperatures of, for example, 100 to 150 ° C.
- An advantage of the method according to the invention results from the low air temperatures that prevail during the ventilation of the water-based lacquer layers. It is thus possible for the flashed-off basecoat layers to be overcoated with a clear lacquer without the bodies having cooled down beforehand.
- all known clearcoats or transparent pigmented coating agents are suitable as clearcoats.
- Solvent-containing one-component (1K) or two-component (2K) clearcoats, water-dilutable 1K or 2K clearcoats, powder clearcoats or aqueous powder clearcoat slurries can be used.
- the stoving conditions of the two-layer coating consisting of waterborne basecoat and clearcoat depend on the clearcoat system used.
- the process according to the invention allows the production of two-coat automotive top coats from an aqueous basecoat and clearcoat topcoat using the wet-on-wet process, with only short flash-off times of 30 to 180 seconds for the basecoat.
- the method according to the invention it is possible to process waterborne basecoats in automated motor vehicle series painting systems which are per se designed for the processing of non-aqueous basecoats and which allow only short flash-off times for the basecoat films. A costly conversion of paint systems which are unsuitable for the processing of aqueous basecoats can be avoided.
- the process according to the invention can even be carried out in such a way that both the waterborne basecoats and non-aqueous basecoats are processed within a motor vehicle series painting system. example
- a car body is coated in a painting booth for experimental purposes:
- the mixture is then vented in a 5 m long ventilation zone with circulating air (water content 12 g per cubic meter) of 40 ° C for 90 s.
