Zirconium Drier for Offset Ink (Through-Drier)
CAS: 22464-99-9
Zirconium octoate is a through-drying (body) drier for oxidatively drying offset inks and varnishes, promoting uniform cure from the surface to the substrate interface and preventing ink set-off and blocking. As a non-colored, non-yellowing auxiliary drier, Zr is particularly valuable in white and light-colored inks where cobalt would cause discoloration, and is increasingly used as the backbone of low-cobalt drier packages.

n-Propyl Acetate (Medium-Evap Solvent for Gravure Ink)
CAS: 109-60-4
Technical-grade n-propyl acetate (n-PrOAc) serves as a medium-evaporation-rate solvent in gravure and high-speed flexographic printing inks, balancing fast press evaporation with sufficient open time to prevent dot gain and plate drying, especially at elevated press speeds. Its high solvency for nitrocellulose, polyurethane, and polyamide resins and low aromatic odor make n-PrOAc the preferred solvent upgrade from ethyl acetate in premium packaging ink formulations.
