Cobalt drier for solvent-based paint systems
Physical Characteristics
Appearance Clear, violet-blue liquid Metal content Co: 11.70 – 12.30 % ISO 4619 Non-volatile content NA Viscosity 500-2000 mPa.s (20°C) ISO 3219 (A) Specific gravity NA Density 1.005 – 1.045 g/cm³ DIN 51757 (20 °C) Solvent Paraffinic mineral oil 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
- Solvent-based systems based on alkyds and epoxy esters that dry by oxidation, including:
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.
