Product Description

General description:

Chemical Formula: C16H30O4Zn

Zinc octoate is a metallic drier widely used in, particularly in paints, varnishes, and inks. It is a zinc-based metal soap formed from the reaction of zinc oxide with octanoic acid (caprylic acid), and it is often diluted with organic solvents for ease of use.It is generally supplied as a clear, amber to pale yellow liquid when diluted in organic solvents. Zinc octoate acts as an auxiliary drier in coatings. It ensures that the coating dries evenly throughout its thickness, preventing surface defects such as wrinkling and ensuring a hard, durable finish.

Application & Usage:

  • An auxiliary drier used as a pigments dispersing agent.
  • Used in paints based on high viscosity media which may have only limited solubility in solvent employed.

Accelerates Drying in Paints and Coatings

Zinc Octoate serves as an excellent drier (accelerator) for alkyd resin-based paints, coatings, and varnishes. It works by promoting rapid surface drying and enhancing the hardness of paint films. This property helps ensure an even and consistent finish, making it invaluable to the coatings and paint industry.


Safe and Stable for Industrial Applications

Formulated as a clear to pale yellow liquid, Zinc Octoate is non-toxic during standard use and remains stable when properly stored. Its high boiling point and low volatility make it safe to handle in industrial settings. Storing the product in tightly sealed HDPE drums extends its usability and maintains optimum performance for up to 12 months.


Versatile Compatibility and Simple Application

Zinc Octoate dissolves well in alkyd resins and most organic solvents, but remains insoluble in water. This compatibility makes it easy to incorporate into various industrial formulations. Its consistency and mild odor minimize disruption to paint texture or scent, facilitating smooth application in manufacturing processes.

FAQs of Zinc Octoate:


Q: How is Zinc Octoate typically used in paints and coatings?

A: Zinc Octoate is commonly added as a drier to alkyd resin-based paints, varnishes, inks, and coatings. Its primary function is to accelerate the surface drying process and enhance the hardness and evenness of the cured film.

Q: What benefits does Zinc Octoate provide compared to other paint driers?

A: Zinc Octoate promotes rapid and uniform surface drying while minimizing discoloration and wrinkling, leading to a smoother, harder finish. Its non-toxic profile under recommended use makes it a safer choice for industrial applications.

Q: When should Zinc Octoate be added during paint formulation or production?

A: It should be added during the mixing stage of paint manufacturing, once the primary components and resins are blended. This allows for even distribution throughout the batch, ensuring consistent drying and finish.

Q: Where should Zinc Octoate be stored for maximum shelf life?

A: Store Zinc Octoate in tightly sealed HDPE drums, positioned away from direct heat and open flames, in a well-ventilated area. Proper storage preserves its performance and extends its shelf life up to 12 months.

Q: What is the recommended process for handling Zinc Octoate during manufacturing?

A: When handling Zinc Octoate, use PPE such as gloves and goggles, ensure good ventilation, and avoid contact with water as it is insoluble. Always close containers promptly after use to maintain stability.

Q: Is Zinc Octoate compatible with all types of paints and solvents?

A: Zinc Octoate is compatible with most alkyd resins and organic solvents, ensuring versatility in a broad range of paint, coating, and ink formulations. However, it is not compatible with water-based systems as it is insoluble in water.
