Cobalt drier for solvent-based systems

  • Physical Characteristics

    AppearanceBlue liquid
    Metal contentCo: 11.90 – 12.10 %
    Non-volatile content65.00 – 72.00 % ASTM D 1644
    ViscosityC to H ASTM D 2373

  • Features

    •  Shortens the surface drying of coatings, varnishes, stains and inks
    • Results in uniform through-drying of the paint film when used in combination with a secondary drier such as zirconium, barium or zinc
    • Catalyzes redox reactions which result in the dissociation of hydroperoxides from a change in valence from Co2+ to Co3+
    • Rapid surface drying

  • Applications

    • Printing 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

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