| Use | The pigment is used less in Europe, mainly in the United States market, non-transparent, is a dark red and yellow variety with good hiding power, showing moderate resistance to cover paint. It is mainly used to replace chrome yellow in the paint, and has a tendency of bleeding in the baking of the alkyd melamine resin paint, and the light fastness is medium; The coloring power in the air self-drying paint is monoazo green yellow C.I. Pigment Yellow 65 times, the natural color is non-transparent type. |
