Zinc 2‑Ethylhexanoate 10% Zn CAS 136-53-8 General‑Purpose Co‑Drier and Anti‑Skinning Agent
Zinc 2‑Ethylhexanoate 10% Zn CAS 136‑53‑8 is versatile liquid auxiliary drier containing 10% zinc metal content. As a general‑grade co‑drier for air‑drying alkyd systems, it effectively suppresses premature oxidation and can‑skin generation during paint storage. When combined with cobalt and manganese primary driers, it promotes uniform cross‑linking, enhances surface hardness and gloss, and reduces film wrinkling defects. It features broad resin compatibility, suitable for large‑scale productio
Product Overview
Zinc 2‑Ethylhexanoate 10% Zn CAS 136‑53‑8 is octoate‑series metal carboxylate auxiliary drier for oxidative alkyd coatings. It cannot produce drying effect independently and must be matched with cobalt‑manganese primary drier packages. Elevated zinc loading delivers stronger anti‑skinning capacity compared with lower‑zinc counterparts. It restricts premature oxidation on liquid paint surface inside sealed containers without impairing surface drying performance after application. It improves cross‑linking homogeneity, minimizes wrinkling risk. It dissolves readily in aliphatic and aromatic hydrocarbon solvents and exhibits good compatibility with long‑oil, medium‑oil and partial short‑oil alkyd resins, maintaining stable performance in storage and repeated industrial batch production.
Key Features
‑ 10% high zinc content provides efficient anti‑skinning performance with low dosage ‑ General‑purpose grade, compatible with multiple solvent‑borne alkyd resin systems ‑ Effectively inhibits can‑skin formation and extends paint shelf storage life ‑ Excellent synergistic effect with cobalt and manganese primary driers ‑ Enhances paint film hardness, gloss and leveling, reduces curing wrinkling ‑ Good solubility in mineral spirits, xylene and common coating solvents ‑ Stable performance for primers, enamels and multi‑type alkyd finished paints ‑ Consistent batch‑to‑batch quality for large‑volume industrial coating manufacturing
Technical Specifications
‑ Product Name: Zinc 2‑Ethylhexanoate (Zinc Octoate) ‑ Zinc Content: 10% Zn ‑ CAS No.: 136‑53‑8 ‑ Appearance: Pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins ‑ Density: 0.97‑1.03 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%
Application Scenarios
‑ General‑purpose long‑oil, medium‑oil solvent‑borne alkyd coatings ‑ Industrial alkyd primers, protective enamels and decorative finishing paints ‑ Alkyd formulas requiring improved anti‑skinning storage stability ‑ Multi‑purpose air‑dry alkyd varnish and pigmented coating systems ‑ Composite drier system cooperating with cobalt‑manganese primary driers
Usage Recommendation
‑ Typical dosage: 0.06%‑0.28% calculated on total paint weight (as metal zinc) ‑ Premix sufficiently 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 drying property evaluation ‑ Complete full 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.
