Abstract
The present invention relates to a solid rubber adhesion promoter composition. It comprises 20-90%, preferably 60-80% by weight of cobalt naphthenate, nickel naphthenate or a mixture thereof and 10-80%, preferably 20-40% by weight of cobalt resinate, nickel resinate or a mixture thereof. The composition can be produced in the form of crisp, non-dusting, friable cast solids, powders or flakes. It has a long shelf life and mixes very well into rubber compounds. By the use of the present promoter compositions strong rubber-to-metal adhesion is obtained.
