Octa-Soligen® Cobalt 14
Description
Cobalt is the most important metal drier. It results in rapid surface drying and, in combination with a secondary drier such as zirconium, barium or lead, uniform through-drying of the paint film.
Octa-Soligen® Cobalt driers are based on metal salts of 2-ethylhexanic acid (octoates) or their isomers.
Supply form
Octa-Soligen® driers are based on octoates or their isomers.
We supply cobalt octoates with different metal contents in different solvents that meet the specific requirements of various applications:

Properties
Octa-Soligen® Cobalt catalyzes redox reactions and even small additions result in the dissociation of autoxidant hydroperoxides up to a change in valency from Co 2+ to Co 3+. Octa-Soligen® Cobalt thus results in rapid surface drying. A surplus of cobalt may result in defects such as wrinkling, poor through-drying and yellowing.
Applications
Octa-Soligen® Cobalt is used in all oxidative systems, whether air-or force-drying.
It is used in architectural paints, industrial coatings, stains, varnishes, oil-based inks and artists' colors.
It can also be used as an accelerator in unsaturated polyester resins, resulting in a shorter gel time.
Addition
In conventional alkyd formulations, the cobalt addition is between 0.03 and 0.08 %, calculated on the solid binder.
In printing inks, a combination of Octa-Soligen® Cobalt and Octa-Soligen® Manganese is recommended. The amount of cobalt is between 0.03 and 0.05 %, calculated on the solid binder.
In systems based on linseed oil, the combination of Octa-Soligen® Cobalt and Octa-Soligen® Cerium yields optimum drying properties. The addition of cobalt metal is 0.02 to 0.06 %, calculated on the solid binder.
Octa-Soligen® Cobalt can also be combined with Octa-Soligen® Zirconium and Octa-Soligen® Calcium. This yields outstanding results in systems that are free from heavy metals.
In unsaturated polyesters, the addition of cobalt is between 0.005 and 0.02 %, calculated on the solid binder.
Irrespective of these guidelines, the addition should always be determined in preliminary trials.
