About Technical Grade Cobalt Octoate
Technical Grade Cobalt Octoate (CAS 136-52-7) is an active organo-metallic catalyst primarily used as a surface drier in alkyd paints and as a curing accelerator for polyester and vinyl-ester resins. It is commonly supplied as a violet-to-reddish-blue liquid with varying metal concentrations (typically 2% to 12%). [

Core Applications
- Coatings & Paints: Acts as the most active surface drier available. It promotes rapid oxidation, hardens the paint film, improves gloss, and prevents moisture ingress. [1, 2, 3, 4, 5]
- Fiberglass (FRP) & Resins: Serves as a crucial accelerator/promoter. When combined with a peroxide catalyst like MEKP, it decomposes the peroxide to cure the resin quickly at room temperature. [1, 2, 3, 4]
- Inks & Rubbers: Used as a drying agent in printing inks and as an adhesion promoter for bonding rubber to metal. [1, 2]
Physical & Technical Properties
- Appearance: Dark violet to reddish-brown liquid.
- Active Components: Cobalt(II) 2-ethylhexanoate dissolved in mineral spirits.
- Molecular Formula: CHCoO
- Specific Gravity: typically 0.85 1.02.
- Safety: Flashpoint is generally around 40 C (104 F). It requires room temperature storage away from heat and direct sunlight. [1, 2, 3, 4, 5, 6, 7]
Technical grade cobalt octoate is widely available through industrial chemical suppliers and manufacturers. Prices in the Delhi/NCR region of India range roughly from 250 to 350 per kilogram. Localized suppliers can be found on industrial platforms such as India-MART or Tradeindia. [1, 2, 3, 4]
