C.I.PY138 1232 SuperFast Yellow KL

1232 SuperFast Yellow KL
C.I.NO.:PY138 Pigment yellow 138 for paints

P.Y.138 type quinophthalone pigments afford exceedingly lightfast and weatherfast greenish yellow shades with good heat stability. Their main fields of application are in paints and in plastics. P.Y.138 is primarily applied in industrial finishes for commercial vehicles, automotive refinishes, and original automotive finishes. Incorporated in these systems,P.Y.138 is acid and alkali fast. However, exterior house paints which are applied onto a basic substrate show some sensitivity to alkali. Types which feature slightly higher specific surface areas are more transparent and demonstrate somewhat different coloristic properties. Such types are not only tinctorially stronger and more greenish but also somewhat less fast to light and weather than opaque varieties, their flow behavior is less favorable.
