Use	This pigment variety gives a greenish yellow color with a hue angle of 95.1 degrees (1/3SD), but less than C.I. Pigment yellow 175, pigment yellow 151 red light, with excellent light fastness and fastness to climate, solvent resistance, good heat stability, mainly used in coatings. The pigment is one of the most light-resistant, weather-resistant yellow varieties, mainly recommended for metal decorative paint and automotive coatings (OEM), good rheology does not affect its gloss at high concentrations; can also be used for soft and hard PVC plastic outdoor products coloring; In the HDPE thermal stability of 210 deg C/5min; For the requirements of light and strong high printing ink (1/25SD printing samples Light 6-7).
