What is Cobalt acetate tetrahydrate?
Cobalt acetate tetrahydrate (CAS 6147-53-1), also known as cobaltous acetate tetrahydrate, is a water-soluble cobalt salt used as a catalyst, drier, and stabilizer.
Where is Cobalt acetate tetrahydrate used?
- Coatings and adhesives: drier catalyst
- Alkyd resins and oil-based systems: accelerates oxidative curing, reducing cycle times
- Polymers and plastics: polymerization catalyst and stabilizer
- PET production: color-correcting agent that offsets yellowing
- Textile and leather processing: mordant and fixative that improves dye uptake and wash fastness
- Agricultural formulations: cobalt micronutrient source in fertilizers and feed supplements
- It delivers controlled cobalt activity where precise metal ion availability drives reaction efficiency or product quality.
Commercial specifications
- Purity typically 98% to 99.5%
- Bulk industrial quantities and smaller packaged lots
