The Radial Tire Industry has used Cobalt compounds for adhesion promoters in wire coat compounds for more than 30 years, because cobalt carboxylates add to the long term adhesion of rubber to brass-coated steel. Heat and humidity-aged properties are improved by the Cobalt mechanism.
Having worked with the Tire Industry to develop an extensive line of Cobalt Carboxylates for this application, Shepherd Chemical is now a leader in the development and sale of these materials. With plants in the USA and France, we are in a position to supply the global requirements of this industry.
Our full range of Cobalt Rubber Adhesion products includes naphthenates and stearates, as well as synthetic acid based.
