Dioxazine Yellow 83 Pigment for Plastic Coating and Painting - Superior Color Strength and Stability

Introduction to Dioxazine Yellow 83 Pigment

Dioxazine Yellow 83 (PY 83) is a high-performance organic pigment renowned for its exceptional color strength, superior lightfastness, and outstanding thermal stability. As part of the dioxazine pigment family, this pigment is widely used in plastic coatings, industrial paints, and specialty inks, where vibrant yellow hues with long-lasting durability are required.

With its high tinting strength and excellent dispersion properties, Dioxazine Yellow 83 is a preferred choice for manufacturers seeking consistent, fade-resistant coloration in demanding applications. Its chemical stability and resistance to migration make it particularly valuable in automotive coatings, packaging materials, and high-temperature plastic processing.

Key Properties of Dioxazine Yellow 83 Pigment

1. Unmatched Color Performance

• High Chroma & Brilliance: Delivers a clean, intense yellow shade with outstanding color purity.

• Superior Tinting Strength: Provides strong coloration at low dosages, reducing formulation costs.

• Excellent Transparency: Ideal for applications requiring deep, rich tones without sacrificing clarity.

2. Exceptional Heat and Light Stability

• Heat Resistance: Stable at temperatures up to 220°C (428°F), making it suitable for high-temperature plastic extrusion and injection molding.

• Lightfastness & Weather Resistance: Exhibits Grade 7-8 lightfastness (ISO 105), ensuring minimal fading in outdoor coatings and automotive finishes.

3. Chemical and Solvent Resistance

• Resistant to acids, alkalis, and most organic solvents, making it ideal for industrial coatings and harsh environments.

• Low migration tendency, preventing bleeding in plasticized PVC and polymer blends.

4. Optimal Dispersion and Compatibility

• Easily dispersible in water-based, solvent-based, and UV-curable systems.

• Compatible with a wide range of resins, including:

  • Polyethylene (PE) & Polypropylene (PP)

  • Polyvinyl Chloride (PVC)

  • Acrylics, Polyurethanes, and Epoxies

Primary Applications of Dioxazine Yellow 83 Pigment

1. Plastic Coatings and Masterbatches

• Used in coloring plastic films, automotive parts, and consumer goods where bright, durable yellows are required.

• Ideal for masterbatch production, ensuring uniform dispersion in engineering plastics and packaging materials.

2. Industrial and Automotive Paints

• Automotive OEM & Refinish Coatings: Provides UV-resistant, long-lasting yellow tones for vehicle finishes.

• Powder Coatings: Used in appliance coatings, architectural finishes, and metal protection.

• Decorative Paints: Suitable for interior and exterior applications due to its fade resistance.

3. Printing Inks and Specialty Coatings

• Flexographic & Gravure Inks: Ensures high printability and color consistency for labels and packaging.

• UV-Curable Inks: Maintains stability under UV curing processes.

4. Textile and Leather Coatings

• Occasionally used in specialty fabric dyes where bright, wash-fast yellows are needed.

Technical Specifications

Advantages Over Competing Yellow Pigments

1. Compared to Cadmium Yellow (Inorganic Pigment)

• Safer & Eco-Friendly: Free from heavy metals (Cd, Pb), complying with REACH, RoHS, and EPA regulations.

• Better Transparency: Unlike opaque cadmium pigments, Dioxazine Yellow 83 allows for clear, vibrant finishes.

2. Compared to Azo-Based Yellows (e.g., PY 12, PY 13)

• Higher Weather Resistance: Performs better in outdoor applications with prolonged UV exposure.

• Superior Heat Stability: More suitable for high-temperature plastic processing.

3. Compared to Isoindolinone Yellows (e.g., PY 110, PY 139)

• More Cost-Effective: Provides similar vibrancy at a lower price point.

• Better Opacity: Covers substrates more efficiently, reducing formulation costs.

Regulatory Compliance & Safety

• REACH & RoHS Compliant: No restricted substances.

• FDA-Certified Grades Available: For indirect food contact applications.

• Non-Toxic & Non-Hazardous: Safe for industrial handling with proper PPE (dust masks recommended).
