Eco Composite Functional Black, developed by Kela Materials, is a composite inorganic black pigment made primarily from the oxides of copper (Cu), manganese (Mn), and iron (Fe). It delivers a purer and more stable black tone compared with organic pigments and carbon black, while offering far superior thermal resistance (up to 800°C).
PBK526 disperses well in both water-based and solvent-based systems and contains **no antimony and no lead**, making it significantly safer for the environment and for human exposure.
As an eco-friendly pigment designed for modern industrial applications, PBK526 provides strong color strength, stable performance, and excellent compatibility across plastics, coatings, ceramics, inks, and functional composite materials.
• High thermal resistance up to 800°C
• Strong black shade with excellent color stability
• Good dispersion in waterborne and solventborne systems
• Free of antimony (Sb) and lead (Pb) for environmental compliance
• Excellent chemical resistance and weather durability
• Suitable for high-temperature and high-performance materials
