Abstract

See full text

Amino alkoxy-modified silsesquioxanes (amino AMS), and/or amino co-AMS compounds that also comprise a mercaptosilane or a blocked mercaptosilane, are excellent adhesives for coating plated or unplated metal wire for adherence of the wire to a rubber stock. The amino AMS and/or the amino/mercaptan co-AMS adhesives can be used with all types of rubber and there is no requirement for the use of special adhesive additives to the rubber vulcanizates, such as, but not limited to, cobalt, resins and high sulfur levels. In particular, the use of amino AMS and/or amino/mercaptan co-AMS compounds as adhesives for bonding wire to rubber also improves the adherence performance of the reinforcements to obtain sufficient bonding that is resistant to degradation over the course of time, especially resistance to thermal aging and/or thermo-oxidizing aging, in particular corrosion in the presence of water.
