Zinc Octoate 8% Zn CAS 136‑53‑8 is liquid zinc 2‑ethylhexanoate auxiliary drier containing 8% zinc metal content. It serves as anti‑skinning co‑drier for oxidative alkyd coating systems. It effectively restricts premature oxidative curing inside sealed paint containers and avoids skin generation. Matched with cobalt and manganese primary driers, it upgrades paint film gloss, surface hardness and leveling property. It reduces wrinkling risk during film forming, maintains good compatibility with g

Product Detail

Product Overview

Zinc Octoate 8% Zn CAS 136‑53‑8 belongs to octoate‑series metal carboxylate auxiliary drier for air‑drying alkyd systems. It cannot realize independent curing effect and must be compounded with cobalt‑manganese primary drier combinations. During paint storage, primary driers may trigger premature oxidation and form tough skin on liquid surface. This product inhibits can‑skin defect without sacrificing surface drying performance on substrates. It improves cross‑linking uniformity of cured films, lowers wrinkling tendency. It dissolves freely in aliphatic and aromatic hydrocarbon solvents, keeps stable catalytic activity throughout paint storage and industrial batch‑to‑batch production.

Key Features

‑ 8% balanced zinc content for mild, stable auxiliary drier activity ‑ Outstanding anti‑skinning performance, suppresses skin formation inside paint cans ‑ Excellent synergistic compatibility with cobalt and manganese primary driers ‑ Improves coating gloss, surface hardness and film leveling performance ‑ Reduces film wrinkling risk during oxidative curing process ‑ Good solubility in mineral spirits, xylene and conventional coating solvents ‑ Fine miscibility with long‑oil and medium‑oil solvent‑borne alkyd resins ‑ Enhances storage stability of finished alkyd paints for mass‑production

Technical Specifications

‑ Product Name: Zinc Octoate (Zinc 2‑Ethylhexanoate) ‑ Zinc Content: 8% Zn ‑ CAS No.: 136‑53‑8 ‑ Appearance: Pale yellow transparent liquid ‑ Solubility: Soluble in aliphatic, aromatic hydrocarbon solvents and alkyd resins ‑ Density: 0.94‑1.00 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ General solvent‑borne long‑oil and medium‑oil alkyd coatings ‑ Industrial alkyd enamel and protective finishing paints ‑ Decorative alkyd paints requiring improved anti‑skinning storage property ‑ Alkyd varnish prone to can‑skin defects during shelf storage ‑ Composite drier system 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 application is ineffective, cobalt‑manganese primary drier combination is mandatory ‑ Adjust addition dosage according to anti‑skinning storage test and surface‑drying evaluation ‑ Complete full‑set laboratory assessment on storage stability, gloss and curing performance 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.
