Product details

Overview

Pigment Black 32 is a high-performance perylene pigment widely used in photovoltaic materials, lithium battery materials, outdoor coiled materials, automotive varnish, refinish paint, anti-counterfeiting coatings, architectural paint, and printing ink.

It features exceptional light fastness, excellent heat resistance, and high color strength, delivering stable and reliable performance for industrial coloring demands. Our strict quality control ensures consistent purity to support your production needs.

Physical And Chemical Properties

- pH Value: 6-7
- Light Fastness: 8
- Heat Resistance: 280℃
- Color Strength: 100±5%
- Moisture Content: ≤ 0.5%
- Oil Absorption: 35±5%
- Odor: Odorless

These physical and chemical properties lay a solid foundation for its stable performance in high-temperature processing, outdoor applications, and special functional coatings.

Advantages

1. Superior Light Fastness: Grade 8 rating ensures exceptional color retention, resisting fading even under prolonged intense sunlight—critical for outdoor applications such as architectural exterior coatings, outdoor coiled materials, and photovoltaic modules.

2. Outstanding Heat Resistance: Withstands temperatures up to 280℃ without color degradation or performance loss, perfectly adapted to high-temperature processing like lithium battery material manufacturing, plastic molding, and automotive paint curing.

3. High Color Strength: 100±5% color intensity guarantees deep, uniform black hues with minimal dosage, reducing material costs while maintaining consistent coloring effects in various substrates.

4. Low Moisture Content: ≤0.5% moisture ensures excellent dispersion in matrices (e.g., battery materials, paint binders, ink resins) and prevents agglomeration, optimizing production efficiency and product quality.

5. Optimized Oil Absorption: 35±5% oil absorption enhances compatibility with different binders and substrates, improving dispersion stability and coloring uniformity in coatings and inks.

6. Neutral pH & Odorless: pH value of 6-7 minimizes corrosion risk to production equipment, while the odorless formula ensures a safe and environmentally friendly working environment during processing.

Application

1. New Energy Materials: Ideal for photovoltaic materials and lithium battery materials, providing stable coloring and compatibility with electrode materials, ensuring no adverse impact on energy storage or conversion performance.

2. Automotive Industry: Suitable for automotive varnish and refinish paint, delivering durable, scratch-resistant color layers with green light undertones that maintain gloss and vibrancy in harsh outdoor conditions.

3. Special Coatings: Applied in anti-counterfeiting coatings (relying on stable physical properties for anti-counterfeiting performance) and outdoor coiled materials, resisting weathering and maintaining color stability for long-term use.

4. Architectural Coatings: Perfect for exterior wall coatings, withstanding UV radiation and temperature fluctuations without fading, enhancing building aesthetics and durability.

5. Printing Ink: Suitable for high-performance printing ink formulations, delivering sharp, fade-resistant prints on various substrates such as paper, film, and packaging materials.
