Industrial Uses

1. Paints, Coatings & Adhesives

  • Primary Drier in Alkyd Paints: Cobalt octoate is the most effective oxidation catalyst, promoting rapid surface drying of alkyd-based paints and coatings.
  • Air-Drying Systems: It accelerates the curing of oil-based and synthetic resin systems by initiating oxidation and polymerization.
  • Ink Drier: Used in printing inks to speed up drying without affecting gloss or color retention.

2. Polymers & Resins

  • Cross-Linking Catalyst: Acts as a catalyst in the cross-linking reactions of unsaturated polyester resins (UPR), particularly in combination with MEKP (methyl ethyl ketone peroxide).
  • Gel Time Control: Controls curing speed and working time in resin casting and molding applications.

3. Construction

  • Concrete Curing Agents: Sometimes used in the formulation of curing compounds and surface coatings for concrete to improve drying time.
  • Sealants & Floor Coatings: Aids in the rapid surface setting of protective floor and wall coatings based on alkyd or resin systems.

4. Lubricants & Automobiles

  • Oxidation Catalyst in Greases: Occasionally used in lithium or calcium-based greases to enhance oxidative stability during high-temperature performance.
  • Adhesive Coatings in Automotive Parts: Assists in the curing of alkyd-based primers and coatings used on automotive components.
