Cobalt is the most common metal drier. It accelerates rapid surface drying and, in combination with a secondary drier such as zirconium, barium or zinc, uniform through-drying of the paint film.

  • Supply Form

    Borchers® Deca driers are based on metal salts of neodecanoic acid (neodecanoates).

    Borchers® Deca Cobalt is available in the following supply forms:

    Borchers® Deca Cobalt 10solventborne systems
    Borchers® Deca Cobalt 12solventborne systems
    Borchers® Deca Cobalt 7 aquasolventborne systems

  • Properties

    Cobalt catalyses redox reactions and even small amounts lead to the dissociation of autoxidanthydroperoxides and to a change in valency from Co2+ to Co3+. Borchers® Deca Cobalt thus initiates rapid surface drying. A surplus of cobalt may result in defects such as wrinkling, poor through-drying and yellowing.

  • Applications

    Borchers® Deca 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’ 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 Cobalt mostly is combined with Borchers® Deca Zirconium and Octa-Soligen® Calcium 10, basic. In printing inks, a combination of Borchers® Deca Cobalt and 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. In case of Borchers® Deca Cobalt 7 aqua, suitable secondary driers are Borchers® Deca Zinc 10 aqua and Octa-Soligen® Zirconium 10 Aqua.

  • 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.
