Pigment Red 177
summary
Pigment Red 177 is a halogen-free blue shade pigment red, has good transparency, and is compatible with molybdenum-chromium red to obtain bright red color, and has good light resistance and weather resistance.
PR177 has good heat resistance, 270 to 280 °C in PE, and heat resistance is significantly reduced when the pigment concentration is less than 0.1%. It is suitable for general polyolefin plastic coloring, bleeding resistance is not good in soft PVC, also suitable for polypropylene, nylon 6 fiber pre-spinning.
PR177 is excellent in light and weather resistance, high in transparency, and widely used in automotive paint motorcycle paint.
