  • Features

    • Promotes uniform through-drying
    • Prevents wrinkling and skinning
    • Excellent drier stability
    • Low viscosity
    • Readily meterable
    • Long shelf-life
    • Improved drying times even under adverse atmospheric conditions
    • Cloudiness and precipitation do not occur

  • Applications

    • All binder systems that that dry by oxidation, especially:
      • White and light-colored paints

  • Dosage

    Experiments have shown that the necessary addition of Octa-Soligen® 203 should be between 2 and 5 % relative to solid binder, depending on the binder 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. Octa-Soligen® Barium 12.5 or Octa-Soligen® Calcium 10 are suitable for this purpose.

    In paint systems which already contain zinc compounds (e.g. zinc-treated titanium dioxide), the zinc in Octa-Soligen® 203 may retard drying. Addition of Octa-Soligen® 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 were commend trials with Octa-Soligen® 173.

  • 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.
