Cobalt Paint Drier: 12% Cobalt with Blend of Synthetic Acids

12% Cobalt Cem-All® is a cobalt drier for solvent-based paint systems. It contains a blend of synthetic acids.

Benefits of Cobalt Driers

This cobalt drier shortens surface drying times for coatings, varnishes, stains and inks. It provides uniform drying of paint films when used with secondary driers.


Ideal applications include architectural and industrial coatings, as well as inks, stains, and artists’ colors. 12% Cobalt Cem-All® siccative works in any oxidatively cured solvent-based system.

  • 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

    •  Oxidatively cured solvent-based systems, including:
      • Architectural paints
      • Industrial coatings
      • Stains
      • Oil-based inks
      • Artists’ colors

  • 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.
