Product Description

General description:

Chemical Formula: (C7H15COO)2Co

Cobalt octoate is the most active surface drier. ... Cobalt octoate being the most effective drier promotes polymerization of media, hardens the paint film, improves gloss and water resistance and reduces brittleness of film. The careful use of Cobalt octoate gives the paint film a good gloss, free from frosting tendency.

Application & Usage:

Most active surface drier.
Used in conjunction with the auxiliary driers.
Promote polymerization of media, hardens the paint film, improve gloss and water resistance and reduces brittleness of film.

Powerful Paint Drier Solution

Cobalt Octoate is expertly formulated to accelerate the drying and curing of paints, varnishes, and inks by catalyzing the oxidation of unsaturated oils. Its deep violet to reddish brown hue signals the presence of active cobalt, ensuring efficient performance in a range of industrial coatings. This product is used widely for improving the drying times of solvent-based systems.

Safe Handling and Storage Recommendations

To maintain effectiveness and ensure safety, store Cobalt Octoate in tightly closed containers within cool, well-ventilated spaces. Because of its toxic nature if ingested and potential to irritate skin and eyes, careful handling, the use of protective equipment, and proper ventilation are essential measures. The product remains stable under ordinary storage conditions and retains its efficacy for at least 12 months.

Versatile Packaging and Shipping Options

Meeting the demands of varied industrial operations, Cobalt Octoate is offered in secure HDPE drums and robust metal barrels, in 25kg, 50kg, and 200kg volumes. This flexible packaging ensures convenience and safety during storage, shipping, and handling. As a trusted exporter and supplier based in India, we provide consistent supply with strict quality adherence.

FAQs of Cobalt Octoate:

Q: How should Cobalt Octoate be used in paint and coating formulations?

A: Cobalt Octoate is typically added to alkyd resins and solvent-based paints or coatings in small proportions as a drier. Its role is to catalyze the oxidation and curing of unsaturated oils, thereby speeding up the drying process. It is important to mix thoroughly to ensure homogeneous distribution.

Q: What safety precautions should be taken when handling Cobalt Octoate?

A: As Cobalt Octoate is toxic if ingested and can irritate the skin and eyes, users should avoid direct contact and inhalation. Always wear appropriate personal protective equipment (gloves, goggles, masks), and ensure good ventilation in the working area. In case of accidental contact, follow standard first aid procedures immediately.

Q: When is the best time to add Cobalt Octoate during paint manufacturing?

A: Cobalt Octoate should be incorporated during the final stages of paint or coating formulation, just before application. This ensures effective dispersion and prevents premature curing which can occur if added too early in the process.

Q: Where should Cobalt Octoate be stored to maximize shelf life and stability?

A: Store Cobalt Octoate in tightly closed containers in a cool, dry, and well-ventilated place. Avoid exposing the product to direct sunlight, heat, or moisture to preserve its stability and extend its shelf life up to 12 months.

Q: What are the main benefits of using Cobalt Octoate in paints and coatings?

A: The primary benefit is its ability to significantly accelerate the drying and curing of alkyd-based paints, varnishes, and inks. It enables faster turnaround times in manufacturing and application, leading to increased efficiency and productivity for industrial users.

Q: Is Cobalt Octoate compatible with all types of resins and coatings?

A: Cobalt Octoate is compatible with most alkyd resins and solvent-based coatings. It is not recommended for use with water-based systems due to its insolubility in water. Always conduct compatibility tests for new formulations.
