Carbon Black Pigment (Furnace Black) for Printing Ink
CAS Number: 1333-86-4
High-structure furnace carbon black designed for maximum jetness, undertone (blue vs. brown), and dispersibility in sheetfed offset, gravure, flexo, and screen black inks. Available in a range of surface area (50–250 m²/g) and structure grades to balance color depth, gloss, flow, and drying performance. Surface-treated and oxidized grades are available for waterborne and UV ink compatibility.
