Typical Applications

Pigment Orange 34 is used in several industrial coloration systems.

Printing Inks: Packaging inks, publication inks, and general printing applications.
Decorative Coatings: Architectural paints and general industrial coatings.
Plastics: Polyolefins, PVC, and general plastic coloration systems.
Packaging Materials: Plastic containers, films, and colored packaging components.
Color Masterbatch: Used in masterbatch production for plastic coloration.

These applications benefit from the pigment’s bright color tone and compatibility with common industrial processes.

Key Performance Properties Related to Applications

Color Shade:
Produces a vivid reddish-orange tone with strong color brightness.

Tinting Strength:
Provides moderate to strong tinting strength suitable for inks, coatings, and plastics.

Dispersibility:
Can be dispersed using conventional milling and compounding equipment.

Solvent Compatibility:
Compatible with many solvent-based and water-based ink and coating systems.

Processing Stability:
Suitable for low to medium temperature processing environments.

Color Development:
Offers consistent color performance in typical binder and resin systems.

Advantages

  • Excellent Flow and Dispersion Properties
    Resinized forms of PO34 offer superior flow and dispersion, giving smooth texture and uniform color distribution, while maintaining good solvent and dry-clean resistance for durable print and coating performance.

  • High Hiding Power and Cost Efficiency
    With strong opacity and good weather resistance, PO34 performs well in industrial coatings such as agricultural machinery and construction paints, serving as a cost-effective and reliable alternative to molybdate red.

Typical Limitations

Moderate Lightfastness:
For long-term outdoor applications, pigments with higher durability may be preferred.

Limited Heat Resistance:
Not typically intended for high-temperature engineering plastics.

Weather Resistance:
Outdoor durability may vary depending on the formulation and exposure conditions.

Buyer Guidance

When evaluating Pigment Orange 34, buyers typically consider:

• Required shade tone (reddish orange vs. yellowish orange)
• Processing temperature of the plastic or coating system
• Lightfastness and weather resistance requirements
• Compatibility with printing ink, coating, or plastic resin systems
• Dispersion performance during manufacturing
• Regulatory and compliance considerations for end-use applications
