    11.90 – 12.10 % Cobalt
    Non-volatile content<=75.00 % ASTM D 1644
    ViscosityA-5 to B ASTM D 2373
    Specific gravity8.05 – 8.44 lb/gal (25°C) ASTM D 1963

  • Features

    • Based on octoate metal salts and designed for solvent-based coatings only
    • Available in a variety of concentrations and organic salts for ease of handling and better solubility
    • Rapid surface drying
    • Catalyzes redox reactions which result in the dissociation of hydroperoxides from a change in valence from Co2+ to Co3+

  • Applications

    • Coatings
      • Architectural
      • Industrial
    • Satins
    • Varnishes
    • Oil-based inks

  • Dosage

    In conventional alkyd formulations, the cobalt addition is between 0.03 and 0.08 % metal-based on the vehicle solids of the coating and will vary upon the composition of the binder. In printing inks, a combination of Cobalt and Manganese driers is recommended. The amount of cobalt is between 0.03 and 0.05 % based on binder solids. Cobalt driers can also be combined with Zirconium and Calcium driers for optimum surface and through dry. The specific drier blend should be experimentally determined.

  • Storage

    Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from sources of ignition. Store in original container. Store in accordance with local regulations. Keep away from food, drink and animal feed stuffs. Keep at temperatures between 5 °C and 30 °C.

  • Safety

    Protect from the effects of weathering and store at temperatures below 50 °C. Once opened, containers should be resealed immediately after each use.
