Manganese Drier
CAS Number: 13434-94-1
A manganese octoate primary metal drier offering an effective, lower-cobalt alternative for accelerating oxidative polymerization in oil-based inks and coatings. Manganese driers provide a favorable balance of surface and through-drying activity, with less tendency to over-oxidize and yellow than cobalt alone. Increasingly favored in low-cobalt ink formulations developed to meet evolving European chemical regulations.
