ABSTRACT:
An aramid reinforcing element or cord is dipped in an aqueous adhesive composition of a phenolic-aldehyde resin and a vinyl pyridine latex and dried. The treatment is repeated again and preferably for three times. The repeatedly treated cord is then cured with a rubber compound to give improved H-adhesion values. If desired, a primer treatment with an epoxide may proceed the aqueous adhesive composition treatments.
