Waterborne Nano Carbon Black Slurry Coating - High Dispersion for Water-Based Paints
Product Overview
Waterborne Nano Carbon Black Slurry is a high-performance colloidal dispersion engineered to deliver unparalleled jetness, conductivity, and UV stability in eco-friendly coating systems. Utilizing proprietary nano-grinding technology, this slurry achieves primary particle sizes of 18–25 nm with 40–45% solid content, offering 98% dispersion efficiency (Hegman ≤10 μm) in waterborne acrylics, polyurethanes, and epoxy formulations. Certified REACH/EPA compliant and free from APEO/NPE surfactants, it enables formulators to meet stringent VOC regulations (<5 g/L) while enhancing functionalities like electrostatic dissipation (surface resistivity down to 10³ Ω/sq) and lightfastness (ΔE <1.0 after 1,000h QUV). Ideal for automotive primers, industrial anti-corrosion coatings, and conductive inks, this slurry redefines carbon black performance in sustainable coating architectures.
