Calcium Drier for Offset Ink (Auxiliary Drier)
CAS Number: 61789-36-4
Calcium octoate auxiliary drier activates and stabilizes primary driers in sheetfed offset ink formulations by coordinating metal-soap interactions and preventing premature over-oxidation that leads to wrinkling. Ca drier improves through-drying balance, extends pot life, and stabilizes the primary drier package over time. It is non-yellowing and non-coloring, making it suitable across the full color gamut in commercial offset ink manufacture.
