Cobalt Neodecanoate 10% Co CAS 27253-31-2 for Offset Ink and Light‑Colored Alkyd System
Cobalt Neodecanoate 10% Co CAS 27253‑31‑2 is oil‑soluble low‑color cobalt‑based primary drier with 10% cobalt metal content. It features high drying activity and low tinting property, perfectly matching offset ink and light‑colored alkyd systems. It accelerates oxidative cross‑linking reaction, shortens surface drying time, avoids obvious yellowing effect on light‑toned films, and shows good compatibility with ink binders and alkyd resins for high‑grade coating and printing ink manufacturing.
Product Overview
Cobalt Neodecanoate 10% Co CAS 27253‑31‑2 is oil‑soluble cobalt neodecanoate developed as high‑activity low‑color primary drier. Compared with conventional cobalt octoate, it brings much less color contamination to light‑colored formulations. When exposed to air, it catalyzes oxidative polymerization of unsaturated components inside offset ink and alkyd resins, achieving rapid surface curing. It dissolves excellently in hydrocarbon solvents, offset ink vehicles and various alkyd resins, maintaining stable catalytic performance during storage and mass production.
Key Features
‑ 10% high cobalt content with low‑color characteristic ‑ Minimal tinting and yellowing influence for light‑colored alkyd systems ‑ Efficient primary surface drying performance for offset printing ink ‑ Good solubility with ink binders and alkyd resin components ‑ Compatible with zirconium, calcium and other auxiliary metal driers ‑ Stable drier activity under regular storage environment ‑ Low‑impurity formula to protect final film appearance ‑ Reliable batch‑to‑batch consistency for industrial‑scale production
Technical Specifications
‑ Product Name: Cobalt Neodecanoate ‑ Cobalt Content: 10% Co ‑ CAS No.: 27253‑31‑2 ‑ Appearance: Light reddish‑transparent liquid ‑ Solubility: Soluble in mineral spirits, xylene, ink vehicles and alkyd resins ‑ Density: 0.98‑1.08 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%
Application Scenarios

Usage Recommendation
‑ Typical dosage: 0.08%‑0.45% calculated on total formula weight (as metal cobalt) ‑ Premix with other drier additives before adding into ink or coating system ‑ Do not add during high‑temperature resin synthesis procedure ‑ Cooperate with zirconium or calcium drier to optimize through‑dry performance ‑ Strictly control dosage to prevent skinning and wrinkling risk ‑ Evaluate drying speed and color change in lab test before mass production
Package & Storage
‑ Standard package: 25kg / 200kg metal drum ‑ Store in cool, dry and well‑ventilated warehouse, keep away from heat and open flame ‑ Tightly seal container after opening to prevent solvent volatilization and oxidation degradation ‑ Shelf life: 12 months under appropriate storage conditions
Safety Notes
‑ Combustible liquid, keep away from all ignition sources. ‑ Avoid skin contact and eye splash. Wear chemical‑resistant gloves and safety goggles during handling. ‑ Prevent inhalation of vapor and mist, ensure effective local ventilation. ‑ Refer to SDS for full information of handling, transportation and emergency treatment
