  • Properties

    Cobalt effects rapid surface drying. In conjunction with cobalt, barium improves through-drying. At the same time it prevents the adsorption of primary drier, thereby increasing drier stability during long-term storage.Zirconium acts as an active auxiliary drier. It improves both through-drying and surface drying.

    The balanced ratio of the various metal contents of Octa-Soligen® 173 yields optimum results in initial drying and through-drying. As a result of the action of the barium, this drier has excellent drier stability,rendering use of additional drier stabilisers unnecessary except in the case of critical pigment Systems.

    Paints incorporating Octa-Soligen® 173 are characterised by better drying times particularly at high atmospheric humidity and low temperatures.

    Octa-Soligen® 173 is of low viscosity, is easy to use and is specifically suited to light-colored paint systems and automotive refinishing paint.

  • Applications

    Octa-Soligen® 173 is usable in all binder systems which dry by oxidation and is particularly suitable to white and light-colored paints. Cloudiness and precipitation do not occur.

    Paint films dried with Octa-Soligen® 173 exhibit very good through-drying, outstanding brightness, good gloss and excellent hardness.

    Octa-Soligen® 173 promotes faster through-drying of paints dried by application of heat. As a result, the paint remains removable with tape (e.g. in the case of automotive refinishing paints) for a shorter period.

  • Dosage

    Applications Development trials showed the necessary addition of Octa-Soligen® 173 to 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 dosage or special stabilization may be necessary. Octa-Soligen® Barium 12.5 and Octa-Soligen® Calcium 10 are suitable for this purpose.

    In paint systems which already contain zinc compounds, Octa-Soligen® 173 should be used in preference to Octa-Soligen® 203.

  • 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.
