Lithium Neodecanoate 2% Li CAS 27253-30-1 Low‑Temperature Surface Drier Co‑Drier
Lithium Neodecanoate 2% Li CAS 27253‑30‑1 is liquid lithium neodecanoate auxiliary co‑drier containing 2% lithium metal content. Its neodecanoate molecular structure delivers good solubility and low‑temperature activity. It effectively promotes surface oxidation cross‑linking when coating is applied under low‑temperature environment, shortens surface drying time. Compounded with cobalt‑manganese primary driers, it mitigates slow‑drying defects in cold construction conditions. It is suitable for
Product Overview
Lithium Neodecanoate 2% Li CAS 27253‑30‑1 belongs to neodecanoate‑series metal carboxylate auxiliary drier for air‑drying alkyd coating systems. It cannot realize independent drying effect and must be matched with cobalt‑manganese primary drier packages. Conventional drier combinations often suffer obvious curing retardation under low‑temperature application environment. This lithium‑based co‑drier retains catalytic activity at cold temperature and accelerates surface drying reaction. It dissolves well in aliphatic solvents and alkyd resins, does not introduce obvious yellowing risk for light‑colored films, maintains stable performance in finished paint storage and industrial batch production.
Key Features
‑ 2% balanced lithium content for mild and stable low‑temperature catalytic activity ‑ Excellent surface drying acceleration performance under cold ambient conditions ‑ Neodecanoate structure with good solubility and relatively low yellowing tendency ‑ Greatly alleviates slow‑drying issue of alkyd coatings in low‑temperature construction ‑ Fine synergistic compatibility with cobalt and manganese primary driers ‑ Compatible with long‑oil and medium‑oil solvent‑borne alkyd resin systems ‑ No negative impact on gloss performance of cured paint film within reasonable dosage range ‑ Stable batch‑to‑batch quality for coatings constructed under variable temperature conditions
Technical Specifications
‑ Product Name: Lithium Neodecanoate ‑ Lithium Content: 2% Li ‑ CAS No.: 27253‑30‑1 ‑ Appearance: Colorless to pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic hydrocarbon solvents and alkyd resins ‑ Density: 0.86‑0.92 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥120℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ Solvent‑borne alkyd coatings requiring construction under low‑temperature conditions ‑ Outdoor decorative and industrial alkyd paints for cold‑season application ‑ Long‑oil and medium‑oil air‑drying alkyd varnish and pigmented enamels ‑ Alkyd formulations suffering retarded surface‑drying at low ambient temperature ‑ Composite drier system cooperating with cobalt‑manganese primary driers
Usage Recommendation
‑ Typical dosage: 0.04%‑0.22% calculated on total paint weight (as metal lithium) ‑ Premix sufficiently with cobalt, manganese and other drier additives before incorporation into coating formula ‑ Do not add during high‑temperature resin synthesis procedure ‑ Standalone use is ineffective, cobalt‑manganese primary drier combination is mandatory ‑ Adjust addition level according to drying test under target low‑temperature condition ‑ Excessive dosage may trigger skinning risk, verify anti‑skinning property after dosage adjustment ‑ Complete full‑set laboratory assessment 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 ‑ Tightly seal container after opening to prevent solvent volatilization and performance 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.
