  • Features

    • Based on metal salts of neodecanoic acid (neodecanoates)
    • Catalyzes redox reactions and even small additions result in the dissociation of autoxidant hydroperoxides and to a change in valency from Co2+ to Co3+
    • Initiates rapid surface drying

  • Applications

    • All oxidative systems, including:
      • Architectural paints
      • Industrial coatings
      • Stains
      • Varnishes
      • Oil-based inks
      • Artists’ oil paints

  • Dosage

    In conventional alkyd formulations, the cobalt amount is in the range of 0.03 to 0.08 % metal, calculated on the solid binder. In paints and varnishes Borchers®Deca Cobaltmostly is combined with Borchers®Deca Zirconium and Octa-Soligen®Calcium 10, basic. In printing inks, a combination of Borchers® Deca Cobaltand Borchers®Deca Manganese is recommended. The cobalt amount is in the range of 0.03 to 0.05 % metal, calculated on the solid binder. 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.
