Cobalt Octoate

Whatsapp Order

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.

Cobalt Octoate

Primary Uses

Paints, Coatings & Varnishes

Used as a drying catalyst in oil-based paints, alkyd resin paints, enamels, varnishes, and lacquers.
Accelerates oxidative drying of drying oils such as linseed oil, tung oil, and soya oil.
Enhances drying speed, film hardness, gloss, and chemical resistance of coatings.
Enables faster production and handling times in industrial and commercial painting applications.

Printing Inks

Incorporated in oxidative drying printing inks to improve drying rate and tack-free time on substrates like paper, metal, and plastic.
Enhances adhesion and surface finish quality.

Adhesives & Sealants

Used in formulations where drying and curing of unsaturated oil-based resins or adhesives is required.
Improves set times and bonding durability.

Secondary Uses

Wood Finishing

Added to wood stains, oils, and lacquers to accelerate drying and improve surface hardness and protection.

Artistic Oil Paint Mediums

Employed in oil painting mediums by artists to reduce drying time without compromising finish or color integrity.

Polymer & Resin Chemistry

Acts as a catalyst in cross-linking reactions of certain resins beyond traditional coatings.

Metal Treatments

Used in specialty protective metal coatings and drying formulations to promote faster curing.

SAFETY HANDLING PRECAUTIONS

Safety Handling Precautions

Personal Protective Equipment (PPE):

Chemical-resistant gloves
Safety goggles or face shield
Respirator if ventilation is insufficient
Protective clothing

Handling Measures:

Avoid inhalation and skin contact
Use in well-ventilated areas or fume hoods
Prevent environmental release

Storage Measures:

Store away from heat, sparks, and open flames
Keep container tightly closed
Ground and bond containers during transfer

Hygiene Practices:

Wash hands thoroughly after handling
Do not eat, drink, or smoke in handling areas

First Aid Measures

Inhalation: Move to fresh air; if breathing is difficult, provide oxygen and seek medical attention
Skin Contact: Wash with soap and water; seek medical advice if irritation or allergy develops
Eye Contact: Rinse with plenty of water for 15 minutes; seek medical care if irritation persists
