Key Performance Properties Related to Applications

Color Shade:
Delivers a medium greenish-yellow tone suitable for process yellow and blending formulations.
Tinting Strength:
Provides good tinting strength, enabling efficient color development in ink systems.
Printability:
Supports stable ink transfer and reproduction in offset and gravure printing processes.
Dispersibility:
Can be processed using conventional dispersion equipment in common binder systems.
Heat Resistance:
Appropriate for low to moderate temperature applications; generally not intended for high-temperature engineering plastics.

Advantages

Bright Greenish-Yellow Shade:
Provides a vivid, clean hue with excellent brightness and visual appeal.
Good Transparency and High Tinting Strength:
Ensures strong color development and vibrant appearance even at low pigment loadings.
Excellent Dispersibility and Processing Stability:
Performs well in various resin systems such as nitrocellulose, polyamide, and EVA copolymers.
Good Heat Resistance (220–240 °C):
Suitable for high-temperature plastic processing and extrusion applications.
Reliable Lightfastness (Grade 4–5):
Maintains color stability under light exposure for durable performance.

Typical Limitations

Lightfastness:
Moderate resistance to light exposure compared to high-performance yellow pigments.
Weather Resistance:
Not typically recommended for long-term outdoor applications.
Thermal Stability:
Limited suitability for high-temperature plastic processing.
