Features

  • Based on metal salts of neodecanoic acids
  • 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 resin. In printing inks, a combination of Borchers® Deca Cobalt and Borchers® Deca Manganese is recommended. The amount of cobalt is between 0.03 and 0.05 %, calculated on the solid resin. Borchers® Deca Cobalt can also be combined with Borchers® Deca Zirconium and Octa-Soligen® Calcium, basic. 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.
