Overview
Zinc octoate (zinc 2-ethylhexanoate) is a metal carboxylate widely used in the coatings, plastics, and printing ink industries. It offers superior performance as a catalyst, stabilizer, and wetting agent. Compared to traditional zinc naphthenate, it provides a lighter color, lower odor, and higher zinc content, making it a preferred choice for modern formulations.

Applications

• Polyurethane coatings and elastomers: Acts as a catalyst promoting crosslinking of aliphatic isocyanates, shortening curing time, and improving final properties.

• PVC heat stabilizer: Used as a secondary stabilizer to enhance thermal stability during processing.

• Paints and coatings: Functions as an excellent wetting agent, suspension agent, matting agent, dispersant, and anti‑fouling additive for marine paints.

• Printing inks: Serves as a gelling agent to control viscosity and rheology.

• Lubricants: Additive to improve performance.

• Fungicide: Provides antifungal properties in appropriate formulations.

Key Benefits

• High zinc content – allows lower dosage for desired performance.

• Light color – suitable for clear and light‑colored formulations.

• Low odor – improves worker comfort and final product quality.

• Excellent compatibility – with a wide range of resins, solvents, and additives.

• Good stability – maintains performance over extended storage periods.

• Versatile – effective in multiple application areas.

Recommended Use
Dosage depends on the specific application:

• Polyurethane catalyst: 0.1–1.0% by weight of total resin solids.

• PVC stabilizer: 0.5–2.0 phr (parts per hundred resin).

• Paint additive: 0.5–5.0% depending on desired effect.

• Ink gellant: 0.5–3.0% for rheology control.

Handling and Storage

• Store in a cool, dry, well‑ventilated area, away from heat and direct sunlight.

• Keep containers tightly sealed to prevent contamination and evaporation.

• Use appropriate personal protective equipment (gloves, safety goggles, protective clothing) when handling.

• Avoid skin contact and inhalation of vapors.

Quality Assurance
Each batch is tested for zinc content, color, viscosity, and acid value to ensure consistent quality and performance.
