Ranbar Red P1610/P1611/P1610T/P1610TA large red organic pigment, DPP red, pigment red 254, gives a neutral red, has excellent solvent resistance, and has a light fastness of 8 level.
Mainly used in automotive primers. Its flocculation can be modified by adding additives. In order to reduce costs, it can be matched with CI Pigment Red 170, which has stronger blue light but lower light resistance, or with quinacridone pigments. Non-transparent blue light red;
It is also widely used for the coloring of plastics (PVC, PS, polyolefin, etc.), in HPDE (1/3) heat-resistant stability at 300°C/5min.
