Blue 15:4 Pigment for Plastic Coatings and Paints
Product Overview
Phthalocyanine Blue 15:4 (PB15:4) is a β-phase copper phthalocyanine (CuPc) pigment renowned for its exceptional crystallinity, chemical inertness, and unmatched versatility across industrial and technological applications. As the most commercially significant blue pigment globally, PB15:4 combines vibrant chromaticity with extreme durability, delivering color strength 4–6 times higher than Prussian blue and 2–3 times superior to ultramarine blue in tinting power. Engineered to withstand temperatures up to 500°C without sublimation or decomposition, this pigment is insoluble in water, alcohols, acids (pH 1–14), and most organic solvents, making it the gold standard for applications requiring long-term color fidelity and structural integrity.
With a precisely calibrated LAB color space (L*: 28–32, a*: −15 to −20, b*: −50 to −55) and optimized particle size distribution (D50: 0.1–0.3 µm), PB15:4 achieves exceptional opacity, transparency on demand, and resistance to abrasion, weathering, and chemical exposure. Beyond its role as a premium colorant, PB15:4 is revolutionizing advanced industries as a functional material in organic photovoltaics, semiconductor devices, and photocurable resin systems. As global demand surges for sustainable, high-performance pigments, PB15:4 dominates markets from automotive coatings to flexible electronics, cementing its status as the highest-volume and most versatile blue organic pigment worldwide.
Key Features & Competitive Advantages
Unrivaled Color Performance
- Extreme Tinctorial Strength: Achieves full opacity at ultralow dosages (0.3–1.5% in masterbatches), reducing formulation costs.
- Bright, Clean Blue Hue: Free from green/red undertones, with a color purity exceeding 98% (CIE 1931 chromaticity diagram).
- Adjustable Transparency: Tailored particle morphology for transparent inks or opaque coatings via surface modification.
Industrial-Grade Durability
- Thermal Stability (500°C): No mass loss or phase change in high-temperature plastics (PPS, LCP) and powder coatings.
- Chemical Resistance: Insoluble in hydrocarbons, esters, and ketones; ideal for fuel-resistant automotive finishes.
- Lightfastness (ISO 105-B02 Grade 8): Zero fading after 2,000+ hours of xenon-arc exposure for outdoor applications.
Multifunctional Utility
- Semiconductor Properties: Bandgap of 1.7–2.2 eV for use in organic field-effect transistors (OFETs) and perovskite solar cells.
- Photoconductivity: Charge generation efficiency >85% in laser printer toners and photocopier drums.
- Photosensitization: Enhances UV curing speed in 3D printing resins and photolithography processes.
Sustainability & Compliance
- REACH, RoHS, and FDA 21 CFR Certified: Safe for food-contact plastics, toys, and cosmetic packaging.
- Halogen-Free & APEO-Free: Complies with OEKO-TEX® Standard 100 and Green Seal GS-11.
- Low Carbon Footprint: Closed-loop production with 95% solvent recovery and renewable energy integration.
Technical Differentiation: α-Phase vs. β-Phase Phthalocyanine Blue
While crude phthalocyanine blue (Type B/β-phase) dominates initial synthesis, its limited color purity and greenish undertones restrict premium applications. PB15:4 undergoes a proprietary phase stabilization process to enhance performance:
- Crystal Structure Optimization: Acid pasting and solvent treatment convert metastable α-phase to stable β-phase crystals.
- Surface Energy Control: Grafting with amphiphilic dispersants (e.g., polyethyleneimine) ensures compatibility in polar/non-polar systems.
- Particle Size Precision: Jet milling and air classification achieve monodisperse nanoparticles (0.05–0.5 µm).
Applications
PB15:4’s unmatched versatility spans traditional and cutting-edge industries:
1. Paints & Coatings
- Automotive OEM/Refinish: High-chroma basecoats, UV-curable clears, and self-healing coatings with 20+ years durability.
- Marine & Aerospace: Antifouling hull coatings, aircraft primers, and thermal barrier coatings resistant to salt spray and jet fuel.
- Architectural: Exterior wall paints, roof coatings, and eco-friendly waterborne systems meeting LEED certification.
2. Plastics & Polymers
- Engineering Plastics: Heat-stable coloring for nylon, PBT, and PEEK in automotive connectors and electronic components.
- Packaging: FDA-compliant masterbatches for PET bottles, HDPE containers, and biodegradable PLA films.
- Synthetic Fibers: Spin-dyeing polyester and polyamide for UV-resistant outdoor textiles and automotive interiors.
3. Advanced Technologies
- Organic Electronics: Hole transport layers (HTLs) in OLED displays and flexible sensors.
- Energy Storage: Coatings for lithium-ion battery separators to enhance thermal runaway resistance.
- Photocatalysis: Sensitizers for hydrogen production and air purification systems.
4. Printing & Inks
- Security Printing: Photochromic inks for banknotes, passports, and anti-counterfeiting labels.
- Packaging Inks: Water-based flexo/gravure inks for food-safe labels and luxury packaging.
- Digital Printing: Toners for high-resolution laser printers and electrophotographic systems.
