Topwellchem’s Perylene Pigment Red 179 is a high-performance perylene pigment designed for industries requiring bold, weather-resistant color. Its bluish-red hue is derived from stable perylene dye chemistry, offering lasting brilliance across coatings, plastics, and inks.
Exceptional Stability for Heat and UV Exposure
With thermal resistance exceeding 300°C and lightfastness rated at 7–8, this perylene pigment maintains color strength in extreme conditions. It is a go-to choice for high-demand environments where traditional perylene red or perylene black pigments may fall short.
Optimized for Industrial Versatility
This perylene dye performs reliably in solvent-based and water-based systems. It is widely adopted in:
- Automotive OEM & refinish coatings
- Engineering plastics & masterbatches
- High-end inkjet & gravure inks
Cost-Effective with Low Migration Risk
Perylene Pigment Red 179 has excellent chemical resistance and low pigment migration, reducing the risk of bleeding or fading—key for industrial buyers seeking long-term product consistency.
Reliable Global Supply with OEM Flexibility
Manufactured under ISO 9001 standards, Nichwellchem ensures batch-to-batch quality and supports large-volume B2B orders with technical consultation and global shipping.
