Ranbar Red P1500 is a brilliant red monoazo organic pigment, Pigment Red 208. This pigment gives a neutral red color with a hue angle of 17.9 degrees (1/3 SD, HDPE). It has excellent solvent resistance and Chemical reagent performance. Mainly used for the coloring of plastic puree and packaging ink, does not migrate in soft PVC, light resistance 6-7 (1/3 SD), heat resistance 200℃, and C.I. Pigment Yellow 83 or carbon black to make brown;
Used for coloring of original polyacrylonitrile pulp, the natural light resistance is level 7;
It is used for coloring of cellulose acetate and polyurethane foam; it can also be used for packaging printing ink. Its solvent resistance and sterilization resistance are good, but its light resistance and weather fastness limit its use in general coatings.
