Effect pigments, aluminium pigments
In functional coatings, it is less the visual effect than the functional properties of the metallic pigments which is the deciding criterion. Corrosion-protection systems are an outstanding example. The lamellar structure of metallic pigments provides effective “barrier protection”. The reflection that results from floating leafing pigments also provides protection against UV and IR radiation. In addition to the barrier function, the lamellar shape of zinc pigment particles offers an extra cathodic or electrochemical protection.
