Cobalt Neodecanoate 12% Co CAS 27253-31-2 Fast Cure Drier for High Solids Industrial Alkyd
Cobalt Neodecanoate 12% Co CAS 27253‑31‑2 is an oil‑soluble high‑activity low‑color cobalt‑based drier with 12% cobalt content. It is specially engineered for high‑solids industrial alkyd systems. It provides fast oxidative cross‑linking curing performance while maintaining low tinting property. It shows excellent compatibility with high‑solid alkyd resins, reduces color interference on coating films, and ensures stable drying efficiency for low‑solvent industrial coating production.
Product Overview
Cobalt Neodecanoate 12% Co CAS 27253‑31‑2 is oil‑soluble cobalt neodecanoate functioning as high‑efficiency fast‑cure primary drier. Its unique neodecanoate structure brings obvious low‑color advantage compared with conventional cobalt octoate. Even within low‑solvent high‑solids alkyd formulations, it can effectively catalyze oxidative polymerization of unsaturated resin segments and accelerate surface curing. It dissolves well in hydrocarbon solvents and high‑solid alkyd resins, keeps stable catalytic activity during storage and industrial production, and lowers the risk of yellowing for light‑toned finished films.
Key Features
‑ 12% high cobalt content for fast‑cure drying performance ‑ Low‑color characteristic, less tinting and yellowing effect on coating films ‑ Optimized for high‑solids low‑solvent industrial alkyd systems ‑ Good solubility and compatibility with various high‑solid alkyd resins ‑ Matches well with zirconium, calcium and other auxiliary driers ‑ Stable catalytic activity under normal storage conditions ‑ Low impurity level to guarantee coating appearance quality ‑ Strict batch‑to‑batch consistency for large‑volume industrial production
Technical Specifications
‑ Product Name: Cobalt Neodecanoate ‑ Cobalt Content: 12% Co ‑ CAS No.: 27253‑31‑2 ‑ Appearance: Light reddish‑transparent liquid ‑ Solubility: Soluble in mineral spirits, xylene and high‑solids alkyd resins ‑ Density: 1.00‑1.10 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ High‑solids industrial alkyd coatings ‑ Low‑solvent industrial finishing paint requiring fast curing ‑ Light‑colored high‑solid alkyd enamel and varnish ‑ Machinery and equipment surface alkyd coatings ‑ Combined with auxiliary driers to achieve complete through‑film drying
Usage Recommendation
‑ Typical dosage: 0.07%‑0.40% calculated on total paint weight (as metal cobalt) ‑ Premix with other drier components before adding into coating formulations ‑ Do not add during high‑temperature resin synthesis process ‑ Cooperate with zirconium or calcium drier to balance surface drying and through‑drying ‑ Strictly control dosage, excessive addition may trigger wrinkling and surface skinning ‑ Adjust dosage according to resin property, solid content and drying requirements ‑ Complete laboratory test on drying speed and color change before mass‑scale production
Package & Storage
‑ Standard package: 25kg / 200kg metal drum ‑ Store in cool, dry and well‑ventilated warehouse, keep away from heat source and open flame ‑ Keep container tightly sealed after opening to prevent solvent volatilization and oxidation deterioration ‑ Shelf life: 12 months under proper 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. ‑ Avoid inhalation of vapor and mist, ensure effective local ventilation. ‑ Refer to SDS for full guidance on handling, transportation and emergency disposal.
