COBALT OCTOATE

It is an auxiliary drier containing cobalt at 1%, 4%, 6%, 8%, 10% and 12%. It is a strong oxidation catalyst for drying oils and is the most effective surface drier known. It is soluble in organic solvents and oils.

It is used as a drier in oil paints and to accelerate the hardening of polyester resins. This accelerator plays a role together with mex peroxide in the hardening of polyester resin, gelcoat and vinylester resins. Cobalt accelerates the reaction at room temperature and helps the hardening of gelcoat, polyester and vinylester, and as a result of this reaction, the composite product reaches its final form.

It is used together with organic peroxides as an accelerator of the curing process of unsaturated polyester resins at room temperature. The product is a dark blue liquid.
