Product Description of Pigment Yellow 191:

The shade of Pigment Yellow 191 is similar to CI Pigment Yellow 83, with low color power, but excellent heat resistance. In high-density polyethylene (HDPE, 1/3 standard depth), it has a heat resistance of 300°C, no dimensional deformation, and has good heat resistance. Light fastness (level 7-8); excellent migration resistance in plastic PVC; temperature resistance up to 330°C in polycarbonate, and resistance to organic solvents. It is mainly used for coloring traffic paint in the United States.

Pigment Yellow 191 is an economical red-shade yellow pigment with excellent heat stability and resistance properties. It is an ideal replacement for diarylide and lead chromate pigments.
