• the paint material is vented.
• these include evaporation or evaporation of existing in the paint material organic solvents and / or water present at most ambient temperature (ie room temperature), for example 15 to 35 ° C for a duration of, for example, 0.5 to 30 minutes to understand.
• organic solvents and / or water that are contained in the applied paint material evaporate.
• the coating material since the coating material is still flowable directly after application and at the beginning of venting, it can run during the venting process. It is namely flowable by the organic solvents contained and / or water and thus can form a homogeneous, smooth coating film by the bleeding.
• the coating layer is not yet ready for use after it has been flashed off. Although it is no longer flowable, for example, it is still soft, possibly only slightly dry. However, it therefore offers a surface suitable for coating with a clearcoat material. In particular, the coating layer is not yet cured as described below.
• the application of the clearcoat material is analogous to the process described above for the color and / or effect paint material. Thereafter, the applied clearcoat material may be flashed off similar to the process described above. However, it then follows the curing (chemical crosslinking) of the clearcoat material via the agent (5).
• This hardening can be effected, for example, by short-term actuation of the means (5), in particular of the lamp, for example in the range of 0.5 to 5 minutes, in which it is held at a distance of about 5 to 30 centimeters above the applied clearcoat material. Subsequently, the clearcoat material is cured, so there is a cured clearcoat.
• Curing is thus understood to mean the transfer of a paint material layer into the ready-to-use state, that is to say into a state in which the substrate equipped with the respective paint material can be used as intended.
• a cured lacquer layer is thus no longer particularly soft or sticky, but conditioned as a solid coating film, which does not significantly change its properties such as hardness or adhesion to the substrate even with further exposure to appropriate curing conditions.
• the color and / or effect coating material is also hardened or at least converted into a state that is dry to the extent that a completely usable substrate (that is to say with the overlying clearcoat layer) results. Because the energy introduced by irradiation with the agent (5) after heat conversion also contribute to the physical and / or chemical (thermal) curing of the color and / or effect paint material. If the color and / or effect paint material is curable even with UV light, hardening of this material obviously proceeds anyway.
• the set according to the invention and the method according to the invention make it possible, on the one hand, to dispense with the very time-, material- and cost-intensive steps of a professional repair, and, on the other hand, to guarantee an acceptable quality with regard to the repair result.
