Abstract
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using various spray conditions. The orientations of individual flakes were determined using laser scanning confocal microscopy. The orientation distribution was then used as input to a ray scattering model to calculate the optical reflectance of these coatings. The pigment orientation distributions and the measured optical reflectance as a function of scattering angle will be presented and the latter will be compared to the calculated reflectance.Citation
