Zinc Neodecanoate 12% Zn White‑Oil Based CAS 27253-29-8 for Low‑Odor Food‑Contact Coating
Zinc Neodecanoate 12% Zn White‑Oil Based CAS 27253‑29‑8 is liquid zinc neodecanoate auxiliary drier with 12% zinc metal content, using purified food‑contact‑grade white mineral oil as carrier solvent. Compared with conventional solvent‑diluted zinc neodecanoate, white‑oil base delivers extremely low odor and low‑volatility advantages. It effectively restricts can‑skin formation during paint sealed storage. Matched with cobalt and manganese primary driers, it promotes uniform oxidative cross‑link
Product Overview
Zinc Neodecanoate 12% Zn White‑Oil Based 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 combinations. This product adopts highly refined white mineral oil as carrier instead of ordinary aromatic or aliphatic solvents. White‑oil base minimizes odor emission and harmful volatile fractions, suitable for formulations requiring incidental food‑contact compliance. It inhibits premature oxidation skin on liquid paint surface inside sealed containers without impairing surface‑drying performance after application. Neodecanoate structure retains excellent low‑yellowing property for pale‑colored films. It shows good miscibility with medium‑oil and long‑oil alkyd resins, maintains stable performance in finished paint storage and industrial batch production.
Key Features
‑ 12% high zinc content for efficient anti‑skinning performance at low dosage ‑ Highly purified white‑mineral‑oil carrier, ultra‑low odor and low‑volatility ‑ Neodecanoate intrinsic low‑yellowing characteristic for light‑color paint films ‑ Inhibits can‑skin formation and extends shelf‑life of finished coatings ‑ Formulated for incidental food‑contact coating application scenarios ‑ Excellent synergistic stabilization effect with cobalt‑manganese primary driers ‑ Improves paint film gloss and leveling, reduces oxidative curing wrinkling ‑ Reliable batch‑to‑batch consistency for high‑purity specialty coating manufacturing
Technical Specifications
‑ Product Name: Zinc Neodecanoate, White‑Oil Based ‑ Zinc Content: 12% Zn ‑ CAS No.: 27253‑29‑8 ‑ Carrier: Highly refined food‑contact grade white mineral oil ‑ Appearance: Colorless to pale yellow transparent oily liquid ‑ Solubility: Soluble in alkyd resins and aliphatic hydrocarbon solvents, insoluble in water ‑ Density: 0.91‑0.97 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥130℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ Alkyd coatings for incidental food‑contact metal substrates and utensils ‑ Low‑odor light‑colored industrial and decorative alkyd paints ‑ Food‑packaging surface protective alkyd coating systems ‑ High‑grade pale alkyd varnish requiring minimal odor release ‑ Composite drier system 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 ‑ End‑formulator shall verify final compliance for food‑contact regulatory requirements ‑ Adjust dosage according to anti‑skinning storage test, odor assessment 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 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.
