    A hybrid ray-wave optics model to study the scattering behavior of silver metallic paint systems

    The gonioapparent lightness of a metallic paint system depends strongly on the 3D microstructure of the platelet-containing basecoat layer, and on the platelet roughness. Current optical models which are used ...

    The characterization and effects of microstructure on the appearance of platelet–polymer composite coatings

    Although color and appearance have a psychological component, they are material properties that can be of considerable significance and economic importance to designers. Paint systems are materials that have a...
