Solvent‑Free Zinc Octoate 23% Zn CAS 136‑53‑8 is solvent‑free high‑concentration zinc 2‑ethylhexanoate auxiliary drier with 23% zinc metal content. No diluting solvent is added into the product, avoiding extra VOC input for solvent‑free and high‑solids alkyd formulas. It effectively suppresses can‑skin formation during paint storage. Combined with cobalt and manganese primary driers, it promotes uniform oxidative cross‑linking, enhances paint film hardness and gloss, reduces wrinkling defects. I

Product Detail

Product Overview

Solvent‑Free Zinc Octoate 23% Zn CAS 136‑53‑8 is octoate‑series solvent‑free metal carboxylate auxiliary drier for air‑drying alkyd systems. It cannot deliver curing performance independently and must be compounded with cobalt‑manganese primary drier combinations. Conventional solvent‑diluted zinc octoate will bring extra volatile solvent, which breaks VOC indicators of solvent‑free and high‑solids formulas. This solvent‑free grade eliminates additional solvent interference. It restricts premature oxidation skin inside sealed containers without impairing surface drying after application. It optimizes cross‑linking uniformity and reduces film wrinkling risk. It shows good miscibility with high‑viscosity solvent‑free and high‑solids alkyd resins, maintains stable performance in production and finished paint storage.

Key Features

‑ 23% ultra‑high zinc content, extremely low effective addition dosage ‑ Solvent‑free formula, zero extra volatile solvent introduced into coating system ‑ Excellent anti‑skinning capacity, inhibits can‑skin for high‑solids alkyd paints ‑ Outstanding synergistic effect with cobalt and manganese primary driers ‑ Improves paint film hardness, gloss and leveling, lowers wrinkling tendency ‑ Optimized miscibility for high‑viscosity solvent‑free and high‑solids alkyd resins ‑ Does not damage VOC specifications of low‑emission coating formulations ‑ Reliable batch‑to‑batch consistency for eco‑friendly high‑solids industrial paint production

Technical Specifications

‑ Product Name: Solvent‑Free Zinc Octoate (Solvent‑Free Zinc 2‑Ethylhexanoate) ‑ Zinc Content: 23% Zn ‑ CAS No.: 136‑53‑8 ‑ Carrier: Solvent‑free, no diluent added ‑ Appearance: Amber high‑viscosity transparent liquid ‑ Solubility: Miscible with solvent‑free and high‑solids alkyd resins ‑ Density: 1.12‑1.20 g/cm³ @25℃ ‑ Viscosity: High‑viscosity liquid ‑ Flash Point: ≥130℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ Solvent‑free alkyd industrial coating systems ‑ Ultra‑high‑solids high‑viscosity alkyd formulations ‑ High‑solids primers and enamels requiring strict VOC control ‑ High‑zinc anti‑skinning formulas sensitive to extra solvent input ‑ Composite drier system cooperating with cobalt‑manganese primary driers

Usage Recommendation

‑ Typical dosage: 0.04%‑0.20% calculated on total paint weight (as metal zinc) ‑ Premix fully with cobalt, manganese and other drier additives before incorporating into coating formula ‑ Do not add during high‑temperature resin synthesis procedure ‑ Standalone use is ineffective, cobalt‑manganese primary drier combination is mandatory ‑ Run compatibility test for high‑viscosity solvent‑free alkyd systems ‑ Adjust dosage according to anti‑skinning storage test, curing property and VOC‑index 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.
