Advantages

Distinctive appearance: It shows a neutral red color, slightly with yellow light compared to C.I. Pigment Red 112, featuring unique color performance.
Wide application scenarios: It can be used in offset printing inks, packaging inks, textile printing and dyeing, and stock dyeing of viscose fibers, adapting to various industrial needs.
Abundant market options: This pigment provides multiple commercial grades to accurately meet different customers’ procurement preferences.

Typical Limitations

Like many traditional azo pigments, Pigment Red 2 also has certain limitations depending on the application environment.

Limited heat resistance compared with high-performance pigments
Moderate lightfastness in outdoor applications
Possible bleeding or migration in some plastic systems
Not typically selected for applications requiring very high durability

Buyer Guidance

When selecting Pigment Red 2 for industrial use, several factors may influence suitability:

Processing temperature of the final application
Required lightfastness and weather resistance
