Dosage

Experiments have shown that the necessary addition of Borchers^® Deca 203 should be between 2 and 5 % relative to solid resin, depending on the resin and the pigment system. This is equivalent to a cobalt content of 0.024 to 0.060 %. When using pigments which retard the drying process such as carbon black or toluidine red, a higher addition rate or special stabilization may be necessary. Borchers^® Deca Barium 12.5 or Octa-Soligen^® Calcium 10, basic are suitable for this purpose. In paint systems which already contain zinc compounds (e.g. zinc-treated titanium dioxide), the zinc in Borchers^® Deca 203 may retard drying. Addition of Borchers^® Deca Zirconium 6 brings about an improvement in many such cases. lt may still be necessary to switch to a different drier system, however, in this case we recommend trials with Borchers^® Deca 173.

Storage
