12% Cobalt Ten-Cem®

12% Cobalt Ten-Cem® by Borchers (Milliken) is a cobalt-based drier. It ensures uniform through-drying of the paint film when used alongside secondary driers such as zirconium, barium, or zinc. It reduces the surface drying time of coatings, varnishes, stains, and inks.

• 12% Cobalt Ten-Cem® is designed for use in oxidatively cured solvent-based systems, including architectural paints, industrial coatings, stains, artists’ colors, and oil-based inks.
• It promotes rapid surface drying by catalyzing redox reactions that decompose hydroperoxides through the conversion of Co²⁺ to Co³⁺.
• The recommended dosage level is 0.03–0.08% metal based on vehicle solids of the coating, and 0.03–0.05% based on binder solids.
