Low‑VOC Cobalt 2‑Ethylhexanoate 12% Co CAS 136-52-7 Eco Industrial Coating Drier
Low‑VOC Cobalt 2‑Ethylhexanoate 12% Co CAS 136‑52‑7 is a high‑concentration eco‑friendly cobalt‑based primary drier. It adopts low‑VOC carrier formula with 12% cobalt metal content. It delivers strong surface curing performance for industrial alkyd coatings while cutting volatile organic emissions. It shows excellent compatibility with high‑solids alkyd resins, meets stricter environmental requirements, and is widely used for manufacturing low‑VOC industrial protective and decorative coatings.
Product Overview
Low‑VOC Cobalt 2‑Ethylhexanoate 12% Co CAS 136‑52‑7 is an environment‑optimized cobalt carboxylate primary drier. Replacing conventional high‑VOC solvent carriers, this product maintains high cobalt activity for oxidative cross‑linking of unsaturated alkyd resins. It effectively accelerates film surface drying for low‑VOC and high‑solids industrial alkyd systems. It mixes homogeneously with alkyd binders and common coating raw materials, keeps stable catalytic performance during storage and mass production, and helps finished products comply with environmental‑oriented coating standards.
Key Features
‑ 12% high cobalt content for fast surface drying performance ‑ Low‑VOC carrier formulation for eco‑friendly industrial coating production ‑ Effective oxidative curing capacity comparable to standard cobalt octoate ‑ Good compatibility with high‑solids and solvent‑reduced alkyd resins ‑ Compatible with zirconium, calcium and other auxiliary metal driers ‑ Stable drier activity under normal storage conditions ‑ Reduces total VOC contribution of finished coating formulations ‑ Reliable batch‑to‑batch consistency for large‑scale industrial manufacturing
