Cobalt Drier
Cobalt Drier is a metal-based drying agent primarily composed of cobalt salts (commonly cobalt octoate or cobalt naphthenate). It is widely used as a catalyst to accelerate the drying (oxidative curing) of oils, alkyd resins, and varnishes in coatings and paints. This drier promotes polymerization and cross-linking of unsaturated fatty acids in drying oils upon exposure to air, significantly reducing drying times and improving film hardness and durability. Cobalt driers are essential additives in industrial, decorative, and automotive coatings due to their effectiveness at low concentrations and compatibility with various resin systems.
Cobalt Octoate
Cobalt Octoate is a liquid metal drying agent solution consisting of 10% cobalt octoate dissolved in an organic solvent carrier (typically mineral spirits or similar hydrocarbon solvent). It functions as a highly efficient catalyst to accelerate the oxidative curing and drying of alkyd resins, oils, and varnishes in coatings and paints. By promoting cross-linking and polymerization of unsaturated fatty acids in drying oils upon exposure to oxygen, it significantly reduces drying time and enhances film hardness, gloss, and durability. Cobalt Octoate 10% is widely used in industrial and decorative coatings, inks, and adhesives, valued for its strong catalytic activity even at low concentrations.
