| Use | There are 13 types of this product. The color is stronger than pigment yellow 74 red light and slightly green light than pigment yellow 65. Although its industrial importance has diminished, it is still marketed in the United States. Natural color in alkyd resin light resistance grade 7-8, light color (1:5 TiO2) is still 7, so despite its low coloring strength, it is still suitable for alkyd resin air self-drying paint, especially as a traffic marker paint colorant. |
