10% Cobalt Hydro-Cure® IV

10% Cobalt Hydro-Cure® IV by Borchers (Milliken) is a cobalt-based drier based on metal salts of neodecanoic acid. It is suitable for oxidatively cured water-based systems. It reduces the surface drying time of coatings, varnishes, stains, and inks.

• It promotes rapid surface drying by catalyzing redox reactions that decompose hydroperoxides through the conversion of Co²⁺ to Co³⁺.
• It ensures uniform through-drying of the paint film when used alongside secondary driers such as zirconium, barium, or zinc.
• 10% Cobalt Hydro-Cure® IV is designed for architectural paints, industrial coatings, stains, artists’ colors and oil-based inks.
• 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.
