C9 Aromatic Hydrocarbon Resin for Ink
CAS Number: 68955-27-1
Aromatic C9 hydrocarbon resin derived from the thermal polymerization of C9 steam-cracker fractions, serving as a high-softening-point tackifier and hardener in offset, gravure, and industrial inks. Its strong aromatic character provides excellent compatibility with rosin-maleic resins and delivers robust tack, gloss, and set characteristics in oil-based ink varnishes.
