ABSTRACT:
The use of metal salts in vulcanizable elastomer compounds is described. In sufficient amounts, the metal salts function as both vulcanization accelerators and adhesion promoters for rubber to metal adhesion, thus eliminating the need for a separate ingredient for each purpose. Certain of the salts also promote the adhesion of the elastomer to metal adherends which have heretofore been unknown, for example, to a zinc surface. Curing characteristics of elastomer formulations using the metal salts are comparable to those using prior art accelerators.
