Cobalt 2‑Ethylhexanoate 12% Co CAS 136‑52‑7 is oil‑soluble high‑concentration cobalt‑based primary drier. With 12% cobalt metal content, it provides powerful fast surface curing performance for short‑oil high‑solids alkyd coatings. It catalyzes oxidative cross‑linking of unsaturated resin segments, adapts to high‑solid‑content formula characteristics, features excellent resin miscibility and stable batch consistency for industrial high‑solids alkyd manufacturing.

Product Detail

Product Overview

Cobalt 2‑Ethylhexanoate 12% Co CAS 136‑52‑7 is high‑concentration oil‑soluble cobalt carboxylate developed as fast primary surface drier. When exposed to air, it accelerates oxidative polymerization of unsaturated groups of short‑oil alkyd resins. High cobalt loading enables quick surface drying even under high‑solids formula with less solvent. It dissolves well in short‑oil alkyd resins and aromatic/aliphatic hydrocarbon solvents, maintains steady catalytic activity during storage and mass production. Proper dosage control avoids film wrinkling and skinning risks.

Key Features

‑ 12% high cobalt content, powerful fast surface drying capability ‑ Specially optimized for short‑oil high‑solids alkyd coating systems ‑ Excellent solubility and compatibility with high‑solid alkyd resins ‑ Accelerates oxidative cross‑linking under low‑solvent formulation condition ‑ Compatible with zirconium, calcium and other auxiliary driers for through‑dry balance ‑ Stable catalytic performance under normal storage ‑ Strict batch‑to‑batch consistency for industrial large‑volume production ‑ Low impurity level to reduce negative influence on coating film appearance

Technical Specifications

‑ Product Name: Cobalt 2‑Ethylhexanoate (Cobalt Octoate) ‑ Cobalt Content: 12% Co ‑ CAS No.: 136‑52‑7 ‑ Appearance: Reddish‑brown transparent liquid ‑ Solubility: Soluble in xylene, mineral spirits and short‑oil alkyd resins ‑ Density: 1.00‑1.10 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ Short‑oil high‑solids alkyd industrial coatings ‑ High‑solid solvent‑borne alkyd enamel and finishing paint ‑ Industrial machinery coatings based on short‑oil alkyd resin ‑ Air‑drying high‑solids decorative alkyd coatings ‑ Combined with auxiliary driers to realize full‑film through‑drying effect

Usage Recommendation

‑ Typical dosage: 0.07%‑0.40% based on total paint weight (calculated as metal cobalt) ‑ Premix with other drier components before adding into coating formulation ‑ Do not add during high‑temperature resin synthesis stage ‑ Match with zirconium or calcium drier to balance surface drying and through‑drying ‑ Strictly control dosage, excessive addition will cause wrinkling and early skinning ‑ Adjust usage according to resin structure, solid content and target drying speed ‑ Complete laboratory formulation test before mass 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 evaporation and oxidation 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 in operation. ‑ Avoid inhaling vapor and mist, maintain effective local ventilation. ‑ Refer to SDS for full information about handling, transportation and emergency treatment.
