Zirconium is a highly efficient secondary drier. Zirconium driers are the most common secondary driers
improving through dry in oxidatively cured coatings primarily by the formation of coordinative bonds when
hydroxyl and carboxyl groups are present.
Zirconium based driers promote through-drying properties and are used in combination with cobalt,manganese, Borchi® OXY-Coat and other surface driers.
12% Zirconium Hydro-Cem driers are carboxylate metal salts designed for waterborne coatings but can be used in solventborne coatings as well. They are used in all oxidatively cured systems, whether air or force dried. They are used in architectural paints, industrial coatings, stains and oil-based inks to promote through drying properties. In comparison to other secondary driers, zirconium has better properties in terms of color,yellowing and stability.
In conventional alkyd formulations, the Zirconium drier addition is between 0.05 – 0.30 % metal based on the vehicle solids of the coating and will vary depending upon the composition of the binder.
Protect from the effects of weathering and store at temperatures below 50 °C. Once opened, containers should be resealed immediately after each use.
