Oil‑Soluble Cobalt Drier 12% Co CAS 136‑52‑7 is high‑concentration cobalt‑based primary drier with 12% cobalt metal content. Tailored for long oil alkyd enamel and anti‑rust protective paint, it delivers powerful oxidative surface curing capability. It features outstanding miscibility with long‑oil alkyd resins and solvent systems, maintains stable catalytic activity, and is widely used for manufacturing air‑drying anti‑corrosive coatings and decorative alkyd enamel.

Product Detail

Product Overview

Oil‑Soluble Cobalt Drier 12% Co CAS 136‑52‑7 is oil‑soluble cobalt 2‑ethylhexanoate serving as high‑efficiency primary surface drier. When paint film contacts air, it catalyzes oxidative cross‑linking of unsaturated groups within long‑oil alkyd resin, effectively shortening surface drying time. This grade is specially adapted for long‑oil alkyd enamel and anti‑rust paint formulations. It dissolves freely in aliphatic, aromatic solvents and long‑oil alkyd binders, keeps consistent drier activity throughout storage and industrial production, and matches well with anti‑rust pigments and fillers in protective coating systems.

Key Features

‑ 12% high cobalt content, strong primary surface drying activity ‑ Excellent oil‑solubility, perfect compatibility with long‑oil alkyd resins ‑ Optimized for long oil alkyd enamel and anti‑rust protective paint ‑ Reliable catalytic performance in pigment‑rich anti‑corrosion coating systems ‑ Compatible with zirconium, calcium and other auxiliary driers for through‑dry balance ‑ Stable drier activity under normal storage conditions ‑ Good tolerance to anti‑rust pigments and mineral fillers ‑ Consistent batch‑to‑batch quality for large‑volume protective coating manufacturing

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 mineral spirits, xylene and long‑oil alkyd resins ‑ Density: 1.00‑1.10 g/cm³ @25℃ ‑ Viscosity: Low‑viscosity liquid ‑ Flash Point: ≥60℃ ‑ Moisture: ≤0.2%

Application Scenarios

‑ Long oil alkyd enamel: decorative and general‑purpose industrial alkyd enamel ‑ Solvent‑borne anti‑rust paint and anti‑corrosive protective coatings ‑ Air‑drying machinery protective paint based on long‑oil alkyd ‑ Alkyd‑based metal surface finishing coatings ‑ Used together with auxiliary driers to achieve complete through‑film curing

Usage Recommendation

‑ Typical dosage: 0.07%‑0.40% calculated on total paint weight (as metal cobalt) ‑ Premix with other drier components before adding into coating formula ‑ Do not add during high‑temperature resin synthesis stage ‑ Combine with zirconium or calcium drier to improve through‑drying performance ‑ Strictly control dosage; excessive addition may cause wrinkling and surface skinning ‑ Adjust addition amount according to resin oil length, pigment loading and drying requirement ‑ Complete laboratory formulation test 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 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 during handling. ‑ Avoid inhalation of vapor and mist, ensure effective local ventilation. ‑ Refer to SDS for full guidance on handling, transportation and emergency disposal.
