Orange peel deriving from the paint system (sheet 1) and from the sheet surface topography (sheet 2)
Using suitable characterising parameters as a basis, these influences can be described by means of empirically determined equations |

The surface topography of sheet, in addition to the paint system and paint application technique, has an influence on the longer-wave components (orange peel) in respect of top coat levelling behaviour. The Institute, commissioned by Studiengesellschaft Stahlanwendung e.V. (see Report P 247), has analysed and formulated these influences for stochastic sheet surfaces.
The visualisation of these influences is possible by scanning the topography over larger areas, in combination with suitable low-pass filtering.
