Studied industrial chemistry at the Westfälische Wilhelms-Universität in Münster.
He started his freelancer career as a designer of car colors before he switched to a more scientific occupation of colors.
Especially interference pigments became his main topic of work.
He influenced the development of new instruments as well as new pigments by his ideas and publications.
He was co-founder of a new committee of ASTM which published in 2008 the "Standard Practice for Multiangle Color Measurement of Interference Pigments".
Visual and instrumental assessment of effect pigments
It is a habit to observe painted panels at a window or in a light booth by tilting them up and down. By doing this the angle of illumination and angle of observation is changing. On the other hand, these panels are measured with instruments with fixed geometries. Insofar, there is a gap between the visual and instrumental assessment. The different results are shown and discussed.
This work deals with similar interference pigments of two manufacturers. Besides direct comparison of color and sparkle the target was to find out how they can be adjusted. For this case original OEM color formulations were used to define the absorbing part of the color. „Playing“ with selected interference pigments shows interesting results.
