• Uses: Cobalt(II) stearate is one of high performance cobalt bonding agent for rubber. It is very suitable for applications in natural rubber, cisdene, styrenebutadiene rubber (SBR) 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. It is ideal direct bonding agents for steel meridian cord tyre, steel wire fortified hoses and conveyors as well as other rubber-metal composite products.
