Cobalt acetate tetrahydrate

Cobalt acetate tetrahydrate (CAS 6147-53-1), also known as cobaltous acetate tetrahydrate, is a water-soluble cobalt salt used across industrial manufacturing as a catalyst, drier, and stabilizer. It delivers controlled cobalt activity in processes where precise metal ion availability drives reaction efficiency or product quality. In coatings and adhesives, it functions as a drier catalyst.

This material accelerates oxidative curing of alkyd resins and oil-based systems, reducing production cycle times. Polymer and plastics manufacturers use it as a polymerization catalyst and stabilizer. It is particularly useful in PET production where cobalt acts as a color-correcting agent to offset yellowing. In textile and leather processing, it serves as a mordant and fixative.

These applications improve dye uptake and wash fastness on treated substrates. Agricultural formulations incorporate it as a cobalt micronutrient source in fertilizers and feed supplements. This is essential where cobalt bioavailability is a formulation requirement. Cobalt acetate tetrahydrate is supplied as pink to red crystalline powder or granules for industrial use.

It is available in technical and reagent grades, with purity levels typically ranging from 98% to 99.5%. Bulk industrial quantities and smaller packaged lots are standard supply formats.
