Zirconium Drier for Offset Ink (Through-Drier)
CAS Number: 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.
