Pigments added to coating formulations to provide an appealing look, besides coloring the coating. For this purpose, aluminum pigments and mica based pearlescent pigments of platelet shape are widely used. There is a special aesthetical expectation from basecoat applications containing metalic or pearlescent (or micaceous) pigments: the flip-flop property. This coating property, formed by parallel allignment of aluminum or pearlescent platelets to the surface, leads to a mirror-like appearance when looked from the front, and to a dark color appearance when looked from a very low angle. Transparency of the film formed by binders enhances the flip-flop effect.
