Abstract: The invention relates to a non-stick coating for a surface of a substrate. In order to significantly improve the non-stick properties compared to the previously known surface coatings and to ensure adequate stability, the surface coating contains at least one fluoropolymer and is characterised by a layer structure with at least one microstructured first layer and at least one submicrostructured second layer overlaying the latter. The invention also relates to a method for producing a surface coating of this type, in which the microstructured subsurface is produced by applying a microstructured layer to a macrostructured surface.

Abstract: In a process for powder coating high temperature resistant surfaces with multilayer coatings, particularly of fluoroplastics, thick coatings can be obtained by maintaining the flowability of the layer previously applied below its run-off limit while applying a subsequent layer.
