Green 7 High Purity Pigment for Coating and Plastic Industries
Product Overview
Phthalocyanine Green 7 (PG7) is a premium-grade, copper-based phthalocyanine pigment renowned for its exceptional crystallinity, thermal stability, and unparalleled coloring power. As one of the most advanced organic pigments in the blue-green spectrum, PG7 exhibits a color strength 4–5 times greater than Prussian blue and significantly outperforms ultramarine blue in opacity, brightness, and chemical inertness. Engineered to withstand extreme conditions, this pigment remains insoluble in most solvents and retains structural integrity even when exposed to temperatures up to 500°C, making it indispensable for high-temperature industrial processes and long-lasting color applications.
With a precisely calibrated LAB color space (L* ≈30–35, a*: −20 to −25, b*: −5 to −10) and exceptional lightfastness (ISO 105-B02 Grade 8), PG7 delivers vibrant, consistent hues across coatings, plastics, and specialty applications. Its unique molecular structure enables dual functionality—serving not only as a superior colorant but also as a critical component in advanced technologies such as organic semiconductors, photoconductors, and photosensitive resin sensitizers. As global demand surges for versatile, sustainable pigments, PG7 has emerged as the most widely produced and utilized blue-green organic pigment, revolutionizing industries from automotive manufacturing to renewable energy.
Key Features & Advantages
Unmatched Color Performance
- Exceptional Color Strength: 4–5x higher tinting power vs. Prussian blue and ultramarine blue, achieving full opacity at low dosages (0.5–2% in masterbatches).
- Precise LAB Color Space: Consistent blue-green tones (CIE Lab*: L* ≈30–35, a*: −20 to −25, b*: −5 to −10) for accurate color matching.
- High Transparency & Gloss: Ideal for metallic effect coatings, transparent inks, and gradient color systems.
Extreme Durability & Stability
- Thermal Resistance (Up to 500°C): No sublimation or chemical degradation in high-temperature plastics (e.g., PEEK, LCP) or powder coatings.
- Chemical Inertness: Resistant to acids, alkalis (pH 1–14), and organic solvents (ethanol, acetone, xylene).
- Lightfastness & Weathering: Grade 8 on ISO 105-B02, ensuring fade resistance in outdoor automotive and architectural coatings.
Multifunctional Applications
- Beyond Colorants: Active role in organic electronics (OFETs, OLEDs), photoconductive films, and photovoltaic devices.
- Photosensitivity: Enhances curing efficiency in UV/EB-sensitive resins for 3D printing and photolithography.
- Semiconductor Properties: Tunable bandgap for use in sensors, memory devices, and flexible electronics.
Sustainability & Compliance
- REACH, RoHS, and FDA 21 CFR Compliant: Safe for food-contact plastics, toy coatings, and cosmetic packaging.
- Halogen-Free & Non-Toxic: Meets OEKO-TEX® and GreenGuard Gold standards for eco-sensitive applications.
- Low VOC Emissions: Compatible with waterborne and solvent-free formulations.
Technical Differentiation: α-Phase vs. β-Phase Phthalocyanine Blue
While industrial crude phthalocyanine blue typically exists in the β-phase (Type B), this form lacks the vibrant blue-green undertones required for premium applications. PG7 undergoes a proprietary pigmentation process to convert β-phase crystals into the α-phase (Type A), achieving:
- Enhanced Color Purity: Removal of reddish undertones for truer blue-green shades.
- Optimized Particle Morphology: Controlled crystal growth (0.1–0.3 µm) via acid pasting and solvent treatment.
- Improved Dispersion: Surface modification with resin-based dispersants for seamless integration into polar/non-polar matrices.
Applications
PG7’s versatility spans traditional coloring and cutting-edge technologies:
1. Coatings & Inks
- Automotive Finishes: High-gloss basecoats, UV-curable clears, and self-healing coatings with 15+ years weatherability.
- Packaging Inks: Water-based flexographic inks for food-safe labels and luxury product packaging.
- Industrial Coatings: Anti-corrosive primers, marine coatings, and heat-resistant aerospace paints.
2. Plastics & Polymers
- Engineering Plastics: High-temperature coloring for nylon, PBT, and PEEK in automotive connectors and electronic housings.
- PVC & Rubber: Non-migrating colorant for synthetic leather, hoses, and weather-resistant window profiles.
- 3D Printing Filaments: UV-stable colorants for photopolymer resins and FDM filaments.
3. Advanced Technologies
- Organic Electronics: Charge transport layers in OLED displays and perovskite solar cells.
- Photocatalysts: Sensitizers for hydrogen generation and wastewater treatment systems.
- Security Printing: Anti-counterfeiting inks with photochromic properties for banknotes and ID cards.
4. Specialty Markets
- Cosmetics: FDA-approved use in nail polishes, hair dyes, and decorative makeup.
- Textiles: Spin-dyeing for UV-resistant outdoor fabrics and automotive interiors.
- Lithium-Ion Batteries: Coatings for battery separators to enhance thermal stability.
