  Premium Cobalt Octoate

  Rated 0 out of 5

  Definition & Composition

  Cobalt octoate is an organometallic compound consisting of:

  • Cobalt ions (6% or 12% active content)
  • Octoate (2-ethylhexanoate) ligands
  • Carrier solvent (typically mineral spirits)

  Primary Function

  Acts as a catalyst to accelerate the oxidative drying of:
  ✔ Alkyd resins
  ✔ Oil-based paints
  ✔ Printing inks
  ✔ Polyester resins

  Key Properties

  Characteristic	Specification
  Appearance	Deep blue/violet liquid
  Density	0.89–0.98 g/cm³
  Flash Point	40–50°C (solvent-dependent)
  Solubility	Compatible with most organic solvents

  How It Works

  1. Oxidation: Promotes oxygen absorption in paint films
  2. Crosslinking: Forms hard, durable polymer networks
  3. Cure Time: Reduces drying by 30–50% vs. uncatalyzed systems
