Combination drier with low cobalt content particularly suited to light-colored paints and varnishes

Description

The combination drier Octa-Soligen® 141 Z is a product developed by our laboratories which combines a large application field with a strong decrease of discoloration caused by cobalt.

With Octa-Soligen® 141 Z the formulators get a lead-free drier system which allows good drying characteristics in medium and long-oil alkyd resins.

  • Properties

    Octa-Soligen® 141 Z is a multi metal drier giving high reactivity, which results of the synergy effects developed by the different metals in the mixture in particular proportions. This allows low dosage and thus a homogeneous and even drying and improves at the same time the hardness of the paint film.

    The even drying results of the low dosage of cobalt allowing a progressive surface drying of the paint film.This effect which is essential for the oxidations within the paint film allows at the same time the evaporation of the solvents

  • Dosage

    The drier Octa-Soligen® 141 Z is a particularly stable product. It is used in formations based on medium and long-oil resins.

    In the case of formulations based on long-oil resins containing drying retarding pigments or pigments causing a loss of drying power (e.g. carbon black or toluidine red) we recommend to add Octa-Soligen® Calcium 10 to the mill base in order to stabilize the drying power.

    The particular composition of Octa-Soligen® 141 Z carries along a modification of the usual calculation methods. In fact, with this new drier it isn’t necessary anymore to maintain the same quantity of cobalt when passing to lead-free systems

    Many tests have allowed determining a reliable and extrapolatable method, which ever resin may be utilized.

    Medium oil resins (40 – 55 %)

    We recommended, for this kind of formulations, the introduction of between 2 and 4 g of Octa-Soligen® 141 Z as supplied per 100 g of resin solids.

    Example: resin of 50 % introduced to 60 % into the formulation:

    Solids content: 30 % x 0.04 = 1.2 % of Octa-Soligen® 141 Z, related to the total formulation.

    Long-oil resins (55 – 75 %)

    We recommend the introduction of between 4 and 6 g of Octa-Soligen® 141 Z as supplied per 100 g of resin solids.

    Example: resin of 65 % introduced to 50 % into the formulation:

    Solids content: 32.5 % x 0.06 = 1.95 % of Octa-Soligen® 141 Z, related to the total formulation.

    If there are strong proportions of drier-adsorbing pigments (due to their high specific surfaces) and/or resins with an oil-length superior to 70 % in this kind of formulations it may become necessary to add Octa-Soligen® Calcium 10 (see separate data sheet).

    In this case the recommended dosage of Octa-Soligen® Calcium 10 is about 50% related to the dosage of Octa-Soligen® 141 Z.

  • 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.
