Applications of Pigment Red 170 in Industrial Manufacturing

Pigment Red 170 is a high-performance azo pigment widely recognized for its strong, bright red shade and excellent fastness properties. It serves as a key chromophore in multiple value chains where precise color, regulatory conformity, process compatibility, and durability are required. The sections below highlight major downstream industrial applications, each reflecting market-verified end uses in which this pigment is a critical raw material.

1. Automotive OEM Coatings

Automotive manufacturers incorporate this pigment into waterborne and solventborne topcoats for both passenger and commercial vehicles. Its high tint strength, light stability, and resistance to bleeding under exterior exposure ensure a consistent, vibrant color during vehicle service life. Tier-one formulators utilize it for matching standard color codes and for specialty finishes, where red is used as a base or effect color. The pigment supports high-speed line application with controlled particle size to maintain gloss and film integrity. Factory audits and downstream traceability require full alignment with automotive OEM standards and documentation for international export.
