In a composite of vulcanizable rubber or rubber-like composition with one or more metal reinforcement elements embedded therein, the metal reinforcement element is coated with a polymer or non-cured rubber composition compatible with and co-polymerizable, co-vulcanizable or crosslinkable with said vulcanizable ruber composition to be reinforced, and additionally bearing functional groups either covalently bonding to the metal surface of said reinforcement element or forming covalent bonds with the outward directed first functional groups of a mono- or multimolecular layer of a bifunctional adhesion promoter intercalated between said metal and said coating and bound to said metal by its second functional groups. A cured rubber or rubber-like product, for instance a pneumatic tire, is obtained by vulcanization of such a composite.

Composite of a vulcanizable rubber composition and cured rubber product

The invention relates to an adhesive substance for improved adhesion between a vulcanizable polymer and a metallic reinforcing carrier. The use of an adhesive substance with the following structure is proposed in order to produce an improved adhesion between rubber and a metallic reinforcing carrier:

Rubber-to-metal adhesion promoter, metal reinforcement, composition made

A rubber article has a body consisting of rubber and a reinforcement structure with cables embedded in the rubber body. The cables have at least one inner layer with at least one first filament wherein at least one first filament consists of a metallic alloy. The outermost layer has second filaments embedded adhesively in the rubber body. All of the first and second filaments that consist of a metallic alloy are coated with a corrosion-protective coating. The corrosion-protective coating for at least one of the first filaments consists of an intrinsically conductive polymer.
