- Such preheating could be done both before applying the coating medium as well as after application. In the latter The case would then be a gradual heating of the surface area to be coated of the body with the coating medium already applied.
- inductive heating could of the body only within partial areas.
- By such targeted heating of only the areas to be coated it is possible to adjacent and / or non-electrically conductive substances or surface areas little or no warming up. A warming of these areas would be then only possible by heat conduction.
- the targeted introduction of heat also enables the coating of individual parts of an overall device and, on the other hand, complete complete devices. Doing so e.g. fully assembled bearings coated entirely or only at selected points become.
- the heating could be carried out in one Surface area with a depth of max. 0.5 mm. With accordingly Short-term warming would be conduction into the remaining areas to neglect the body to be coated.
- a gaseous or liquid cooling medium could be used as the cooling medium
- Form of, for example, air, water or oil can be used. This would be temperature sensitive Areas easily protected from the effects of temperature. Only by using induction heating is it possible to be temperature sensitive Places or areas of the body to be coated at the same time as the heating the surface areas to be coated with air or liquid Cool cooling media.
- Induction heating processes shorten the response time with a significant increase in the crosslinking temperature to achieve a fully crosslinked Coating conditionally, which is only in their fully networked scope their favorable Features fully. Too high a temperature can, however Destruction of the network or the pigments and additives embedded in it to lead. As a result, cooling the body at the appropriate time may differ bring positive effects. The cooling could only be achieved after this the reaction temperature can be used.
- the coating could be a have cathodic effect.
- the coating could in addition or as an alternative to the cathodic effect, it is electrically and / or thermally conductive his. Almost metallic conductivity could be achieved.
- the coating could have a layer thickness from about 2 to 30 microns. This might be the case extreme corrosion protection in the thinnest layers. In more advantageous The coating could also be weldable.
- the coating could have no heavy metals and in particular free of chromium VI and cadmium his.
- the control of the layer thickness could, on the one hand, be based on the viscosity of the Coating medium and on the other hand or additionally via a mechanical Deduction must be set. With a view to mechanical removal this can be done in a simple manner by skidding. All other known Paint application methods are also applicable.
- an additional organic top layer could be applied to the coating be upset.
- the composition of the top layer could be considered for the best possible adhesion to the composition of the coating be coordinated.
- the binder has a significant influence. in the In connection with the application of organic cover layers are high molecular weight aminically cross-linked epoxy / phenoxy binders of the top layer in particular Cheap.
