Borchers^® Deca Cobalt 10 (xylene)

Supply Form

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

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

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.
