| Résumé : |
When considering yellow pigments for automotive OEM and refinishing paints, benzimidazolone azo pigments and possibly quinophthalone pigments come to mind as opaque organic yellow pigments. The introduction of water-based paint systems has, however, revealed the performance limits of these pigment groups. The important properties for using in automotive OEM paints are : weathering fastness and overcoating fastness in multicoat systems. Now P.Y. 213, a halogen-free azo pigment based on a quinoxalinedione coupling component could well provide a solution to these problems. |
