Zinc Neodecanoate 12% Zn CAS 27253-29-8 High‑Zinc Anti‑Skinning Alkyd Drier
Zinc Neodecanoate 12% Zn CAS 27253‑29‑8 is high‑concentration liquid zinc neodecanoate auxiliary drier with 12% zinc metal content. It combines high zinc loading with neodecanoate advantages of low odor and low yellowing. It effectively suppresses can‑skin formation during paint sealed storage. When compounded with cobalt and manganese primary driers, it promotes uniform oxidative cross‑linking, enhances paint film gloss and hardness, reduces curing wrinkling defects. High zinc content lowers ad
Product Overview
Zinc Neodecanoate 12% Zn CAS 27253‑29‑8 belongs to neodecanoate‑series metal carboxylate auxiliary drier for air‑drying alkyd coating systems. It cannot realize drying function independently and must cooperate with cobalt‑manganese primary drier combinations. Compared with lower‑zinc neodecanoate grades, higher zinc concentration delivers stronger anti‑skinning capacity without sacrificing low‑odor and low‑yellowing merits of neodecanoate structure. It restricts premature oxidation skin on liquid paint surface inside sealed containers and does not impair surface drying performance after application. It optimizes cross‑linking homogeneity and minimizes film wrinkling risk. It dissolves well in dearomatized aliphatic solvents and various alkyd resins, maintains stable performance in finished paint storage and industrial batch production.
Key Features
‑ 12% high zinc content, powerful anti‑skinning effect with low addition dosage ‑ Inherent neodecanoate advantages: low‑odor and low‑yellowing property ‑ Remarkably inhibits can‑skin formation and extends shelf‑life of light‑color alkyd paints ‑ Excellent synergistic compatibility with cobalt and manganese primary driers ‑ Improves paint film hardness, gloss and leveling, reduces curing wrinkling tendency ‑ Good solubility in dearomatized mineral spirits and common coating solvents ‑ Suitable for pigment‑rich light‑toned alkyd coating formulations ‑ Reliable batch‑to‑batch consistency for high‑grade industrial paint mass‑production
Technical Specifications
‑ Product Name: Zinc Neodecanoate ‑ Zinc Content: 12% Zn ‑ CAS No.: 27253‑29‑8 ‑ Appearance: Colorless to pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic hydrocarbon solvents and alkyd resins ‑ Density: 0.92‑0.98 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥120℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ White and pastel light‑colored alkyd varnish and decorative enamels ‑ Industrial solvent‑borne alkyd coatings requiring strong anti‑skinning performance ‑ High‑grade furniture alkyd finishes with low‑odor and low‑yellowing requirements ‑ Pigment‑loaded light‑shade alkyd systems prone to can‑skin defects ‑ Composite drier formula cooperating with cobalt‑manganese primary driers
Usage Recommendation
‑ Typical dosage: 0.05%‑0.24% calculated on total paint weight (as metal zinc) ‑ Premix fully with cobalt, manganese and other drier additives before adding into coating formula ‑ Do not add during high‑temperature resin synthesis procedure ‑ Standalone use is ineffective, cobalt‑manganese primary drier combination is mandatory ‑ Adjust dosage according to anti‑skinning storage test, odor and anti‑yellowing evaluation ‑ 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.
