| Use | There are 126 types of this product. Used for ink and paint coloring important varieties, green light yellow (between is C.I. Between pigment yellow 1 and pigment yellow 3), the coloring intensity is higher than that of the general monoazo pigment; More than C.I. Pigment Yellow 12 slightly red light, 1/3SD pigment yellow 12 need 4.5%, and pigment yellow 74 need 4.2%; There are different particle size varieties (specific surface area of 10-70m2/g, the specific surface area of Hansha yellow 5GX02 was 16 m2/g, and the large particle size dosage form (10-20 m2/g) showed high hiding power. Compared with the fine particle size variety, the non-transparent display is more red light, more light resistant, and the freshness is slightly lower, especially suitable for the coating industrial air self-drying paint, which can increase the concentration and further improve the hiding power without changing the rheological property, and can be used |
