Typical Applications

Pigment Yellow 93 is commonly used in several industrial sectors.

Printing Inks: Flexographic, gravure, and other packaging printing inks.
Industrial Coatings: Decorative coatings, general industrial paints, and maintenance coatings.
Plastics: Coloring of polyolefins, PVC, and masterbatch formulations.
Packaging Materials: Flexible packaging inks and decorative printing.
Paper and Board: Colored paper coatings and printing applications.

These uses take advantage of the pigment’s compatibility with common industrial binder systems.

Key Performance Properties Related to Applications

Color Shade:
Produces a bright yellow to slightly greenish-yellow tone with clean color appearance.

Tinting Strength:
Provides moderate to good tinting strength suitable for coatings and printing ink formulations.

Dispersibility:
Can be dispersed using conventional milling equipment in many ink and coating systems.

Lightfastness:
Offers moderate lightfastness depending on the formulation and pigment concentration.

Heat Resistance:
Suitable for typical coating curing conditions and standard plastic processing temperatures.

Chemical Stability:
Shows stable performance in many common solvent and resin systems.

Advantages

  1. Excellent light and weather fastness (Grade 7 at 1/3 & 1/25 SD)

  2. High thermal stability (up to 290°C in HDPE)

  3. Strong solvent and migration resistance

  4. Suitable for plastics, coatings, and ink

• Typical Limitations

Moderate Outdoor Durability:
Not primarily intended for long-term outdoor exposure without additional stabilization.

Heat Resistance Limits:
May not be suitable for high-temperature engineering plastics.

Lightfastness Variation:
Performance may vary depending on binder system, pigment concentration, and exposure conditions.

Buyer Guidance

When evaluating Pigment Yellow 93, buyers typically consider:

• Required shade tone (yellow vs. greenish yellow)
• Intended exposure conditions (indoor or outdoor use)
• Processing temperature of the plastic or coating system
• Required tinting strength and opacity
• Compatibility with printing ink or coating resin systems
• Regulatory and compliance considerations
