Perylene Black

Description

1. Product Overview
Perylene Black is a high-performance, polycyclic organic pigment engineered for applications demanding exceptional near-infrared (NIR) absorption and superior lightfastness. Its primary industrial use is in advanced coatings, security inks, and high-durability plastics where carbon black fails due to NIR transparency requirements. The key value proposition is its unique molecular structure that provides deep black color with controlled NIR reflectance, making it strategically critical for defense, automotive, and solar thermal management systems.

2. Key Specifications & Technical Characteristics

• Chemical composition: Perylene diimide derivative (C.I. Pigment Black 31 or 32 equivalent)

• Purity level: ≥98.5% (HPLC)

• Physical characteristics: Fine powder; jet-black color; mean particle size D50 = 0.15–0.35 µm; density = 1.6–1.7 g/cm³

• Packaging options: 20 kg net in kraft paper bags with PE liner; 500 kg bulk FIBCs

• Shelf life: 60 months when stored below 30°C in original, sealed container away from UV exposure

3. Core Industrial Applications

• Primary industries: Aerospace & defense coatings, laser marking plastics, security printing, and solar thermal collectors.

• Operational use cases: Radar-absorbing camouflage coatings (NIR management) and anti-counterfeit banknote inks (unique spectral signature).

• Performance advantage: Unlike carbon black, Perylene Black allows NIR detection or heat regulation while maintaining deep color; it also demonstrates 3–5x longer outdoor durability than conventional organic black pigments.

4. Competitive Advantages

• Quality consistency: Lot-to-lot ΔE < 0.5 per ISO 787-25; 100% tested for NIR reflectance curve stability.

• Supply reliability: Dual-sourced raw material pathway with 250 MT annual dedicated capacity.

• Logistics capability: Just-in-time shipping from regional hubs (Asia, EU, NA) via ocean, air, or rail.

• Sustainability: REACH and RoHS compliant; heavy-metal-free; lower carbon footprint vs. inorganic black pigments.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 1 MT (1,000 kg) for first trial order

• BULK 20MT: Standard contract lot size

• Loading capacity: 20 MT per 20-ft dry container (FIBC-packed)
