Use	The pigment species belongs to benzimidazolones, giving a reddish brown color with a hue angle of 43.5 degrees (1/3SD,HDPE), but less than C.I. Pigment Brown 23 has a stronger yellow light and is more transparent. PV-Fast Brown HFR 01 specific surface area of 90 m2/g. Mainly used in paint, printing ink and plastics, such as automotive primer (OEM), repair paint; And iron oxide red inorganic pigment fight brown to red brown; Excellent light resistance, weather fastness, light fastness in light colored (1:300 TiO2) alkyd melamine is still up to grade 7-8; Heat-resistant in PVC 200 ℃, light fastness to grade 8, HDPE heat-resistant 290 ℃, less than 220 deg C size deformation is not obvious; Can also be used for polyacrylonitrile and PP spinning coloring.
