Zinc Neodecanoate 8% Zn CAS 27253-29-8 Anti‑Skinning Co‑Drier for Pale Alkyd
Zinc Neodecanoate 8% Zn CAS 27253‑29‑8 is liquid zinc neodecanoate auxiliary drier containing 8% zinc metal content. Compared with conventional zinc octoate, neodecanoate molecular structure provides excellent low‑yellowing and low‑odor characteristics. It effectively restricts can‑skin formation during paint sealed storage. When matched with cobalt and manganese main driers, it promotes uniform oxidative cross‑linking, enhances paint film gloss and leveling, and reduces curing wrinkling defects
Product Overview
Zinc Neodecanoate 8% Zn CAS 27253‑29‑8 belongs to neodecanoate‑series metal carboxylate auxiliary drier for air‑drying alkyd coating systems. It cannot achieve drying effect independently and must be compounded with cobalt‑manganese primary drier sets. Traditional octoate zinc driers may trigger discoloration for light‑toned coatings under aging condition. This neodecanoate grade greatly suppresses yellowing tendency while maintaining outstanding anti‑skinning capacity. It inhibits premature oxidation skin on liquid paint surface inside containers without damaging surface drying performance after construction. It improves cross‑linking homogeneity of cured film and lowers wrinkling risk. It dissolves well in dearomatized aliphatic solvents and various alkyd resins, keeps stable performance in finished paint storage and industrial batch production.
Key Features
‑ 8% balanced zinc content for mild and stable anti‑skinning auxiliary activity ‑ Neodecanoate structure with remarkable low‑yellowing and low‑odor properties ‑ Effective can‑skin inhibition to extend shelf‑life of pale alkyd coatings ‑ Excellent synergistic compatibility with cobalt and manganese primary driers ‑ Improves paint film gloss and leveling, reduces oxidative curing wrinkling ‑ Good solubility in dearomatized mineral spirits and common coating solvents ‑ Specially optimized for white, transparent and light‑shade alkyd resin systems ‑ Reliable batch‑to‑batch consistency for high‑grade light‑color paint mass‑production
Technical Specifications
‑ Product Name: Zinc Neodecanoate ‑ Zinc Content: 8% Zn ‑ CAS No.: 27253‑29‑8 ‑ Appearance: Colorless to pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic hydrocarbon solvents and alkyd resins ‑ Density: 0.89‑0.95 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥120℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ Pale clear alkyd varnish and white light‑colored decorative alkyd coatings ‑ High‑grade furniture finishing alkyd paints requiring low yellowing performance ‑ Light‑toned industrial solvent‑borne alkyd enamels ‑ Alkyd formulations prone to can‑skin defect and sensitive to discoloration ‑ Composite drier formula cooperating with cobalt‑manganese primary driers
Usage Recommendation
‑ Typical dosage: 0.07%‑0.30% 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 and anti‑yellowing color stability 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.
