Cobalt Catalyst is the most important metal drier. It results in rapid surface drying, and, in combination with secondary drier, such as zirconium, barium or zinc, in uniform through-drying of the paint film. This is a polymerization promoter for unsaturated polyester resins as well at room temperature. It is cobalt sale of 2-ethylhexanoic acid (octates) or their isomers. We are supplier of cobalt in Pakistan.

Cobalt is used in all oxidative systems, whether air-or forced-drying. It is used in architectural paints, industrial coatings, stains, varnishes, oil-based inks and artists’ colors. Cobalt can also be used in all solvent based Unsaturated Polyester Resins or vinyl ester applications to promote crosslinking. It is the lightest, commercial cobalt catalyst available and is recommended specifically for use in gel-coats and castings where color is critical.
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 Cobalt and Manganese is recommended. The amount of cobalt is between 0.03 and 0.05 %, calculated on the solid binder.
Cobalt can also be combined with Zirconium and Calcium. This yields outstanding results in systems that are free from heavy metals.
Irrespective of these guidelines, the addition should always be determined in preliminary trials
