Abstract

A series of experiments was carried out to investigate the relationship between the microstructure and the appearance of coated materials using confocal laser microscopy and optical scattering metrology. Microstructural properties such as surfaces roughness, pigment particle size and size distribution affect optical scattering distribution of the sample, resulting in different appearances. In this presentation, preliminary research on two pigmented coating systems - TiO₂ and metallic-flake pigmented coatings - are presented. By integrating measurements and modeling, a methodology for predicting the appearance of a coating from its microstructure and constituents is proposed.
