Product features
- As a near IR Reflective organic black with high tintoral strength, it is highly recommended for coatings, inks and other applications. This advanced perylene pigment delivers deep, high – saturation black shades, outperforming standard black formulations and offering better coverage than perylene red in dark – tone applications.
- It also has outstanding heat and UV resistance, maintaining performance under extrusion and outdoor exposure, ensuring lasting color in plastics and coatings.
- Moreover, it shows broad industry compatibility, dispersing easily and staying stable in solvent – based coatings, engineering plastics, or ink systems.
- It has low migration and high purity, making it ideal for sensitive applications such as food packaging or toys.
- This versatile pigment is widely used in various fields. It is suitable for coatings and paints, helping to create durable and beautiful coatings. In plastic manufacturing, it can give plastics excellent color performance and stability. It is also an important component in inks and printing, ensuring clear and long – lasting printing effects.Additionally, it has applications in textile applications, bringing unique color characteristics to textiles.
Applications
- Infrared-Reflective & Thermal Insulation Coatings:
Used in building facades and industrial equipment coatings to reflect NIR radiation (＞45% reflectivity over white substrates), reducing surface temperatures and energy consumption. - Automotive Paints:
High-end OEM finishes, repair coatings, and black high-reflectivity photovoltaic backsheets, balancing aesthetics with thermal management. - Military Camouflage Materials:
Utilizes IR transparency for low-thermal-signature coatings to counter infrared detection. - Plastics & Inks:
Engineering plastics (heat-resistant to 350°C), in-situ polyester fiber dyeing, and premium printing inks. - Research & Biological Fields:
Biomolecular labeling, cell staining, and dye-sensitized solar cells
