Low‑VOC Cobalt Octoate 6% Co CAS 136-52-7 Zero‑VOC Carrier for High Solids Alkyd
Low‑VOC Cobalt Octoate 6% Co CAS 136‑52‑7 is an environment‑friendly cobalt‑based primary drier adopting zero‑VOC carrier. With 6% cobalt metal content, it is specially developed for high solids alkyd coatings. It maintains effective surface‑drying catalytic activity, conforms to low‑VOC formulation requirements, and delivers good compatibility with high‑solid alkyd resins, helping manufacturers produce low‑emission industrial and decorative alkyd paints.
Product Overview
Low‑VOC Cobalt Octoate 6% Co CAS 136‑52‑7 is a cobalt 2‑ethylhexanoate drier formulated with zero‑VOC carrier. Different from conventional solvent‑borne cobalt driers, it minimizes volatile organic compound release while retaining the core catalytic function of cobalt. When incorporated into high‑solids alkyd systems, it catalyzes oxidative cross‑linking of unsaturated resin chains to accelerate film surface drying. It exhibits excellent miscibility with various high‑solid alkyd resins, keeps stable drier activity during storage and production, and supports coatings to meet stricter environmental protection standards.
Key Features
‑ 6% cobalt content, zero‑VOC carrier design for low‑emission formulations ‑ Low‑VOC eco‑friendly primary surface drier for high solids alkyd ‑ Reliable oxidative curing performance comparable to standard cobalt octoate ‑ Excellent compatibility with different high‑solid alkyd resin grades ‑ Compatible with zirconium, calcium and other auxiliary driers ‑ Stable catalytic activity under normal storage conditions ‑ Helps finished coatings satisfy low‑VOC regulatory requirements ‑ Consistent batch‑to‑batch quality for industrial mass production
