  • Features

    • Based on metal salts of 2-ethylhexanoic acid (octoates) or their isomers
    • Catalyzes redox reactions and even small additions result in the dissociation of autoxidant hydroperoxides and to a change in valency from Co2+ to Co3+
    • Rapid surface drying

  • Applications

    • Solvent-based systems based on alkyds and epoxy esters that dry by oxidation, including:
      • Printing inks

  • Dosage

    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. 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. Irrespective of these guidelines, the addition should always be determined in preliminary trials.

  • Storage

    Protect from the effects of weathering and store at temperatures below 50 °C. Once opened, containers should be resealed immediately after each removal of the product.
