ABSTRACT:
A method for improving metal adhesion and metal adhesion properties between a vulcanizable rubber composition and brass or zinc or brass-plated or zinc-plated metallic reinforcing elements includes dispersing from about 0.5 to about 12.5 parts by weight of an organic salt of nickel or cobalt per 100 parts of rubber component in a sulfur vulcanizable rubber composition and dispersing from about 0.5 to 15 parts by weight of a thermosetting two-step phenolic resin per 100 parts of the rubber component in the same rubber composition prior to curing.
