| Use | There are 52 kinds of commercial dosage forms of the pigment, which is one of the important orange pigments. There are two different particle size products, the particle size of large (Irgalite red 2GW specific surface area of 14 m2/g) red light is stronger, high hiding power, light fastness 6 grade, dilute color fastness decreased. Mainly used for air self-drying paint; Can also be used for offset printing ink, packaging printing ink, paint printing paste demand is large, its light fastness up to 7; Can also be used for hard PVC (light fastness 8), paper coloring, Art color. It is mainly used in ink, paint, paint printing paste, watercolors and oil-color pigments and pencil, and can also be used in rubber and plastic products. |
