Infobox references

Cobalt(II) stearate is a metal-organic compound, a salt of cobalt and stearic acid with the chemical formula C
36H
70CoO
4.[3][4] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.[5]

Synthesis

Cobalt(II) stearate can be precipitated by reacting sodium stearate and cobalt dichloride:[6]

CoCl2 + 2 C17H35COONa → Co(C17H35COO)2 + 2 NaCl

Uses

Cobalt(II) stearate is a high-performance bonding agent for rubber. The compound is suitable for applications in natural rubber, cisdene, styrene-butadiene rubber, and their compounds to bond easily with brass- or zinc-plated steel cord or metal plates as well as various bare steel, especially for bonding with brass plating of various thicknesses.[7]
