Octa-Soligen® Cobalt 6

Octa-Soligen® Cobalt 6 by Borchers (Milliken) is a cobalt drier based on metal salts of 2-ethylhexanoic acid (octoates) or their isomers. It helps in catalyzing redox reactions, and even small additions lead to the dissociation of autoxidant hydroperoxides and to a change in valency from Co²⁺ to Co³⁺.

• It promotes rapid surface drying.
• It is used in solvent-based systems based on alkyds and epoxy esters that dry by oxidation, including unsaturated polyesters.
• Typical usage level of Octa-Soligen® Cobalt 6 is 0.03-0.08% based on total solid binder.
