Abstract
Use of an effective amount of a specific combination of silicone compounds comprising the combination: PA1 of at least one functionalized polyorganosiloxane (abbreviated as POS) containing, per molecule, at least one functional siloxy unit (abbreviated as UN1) capable of binding chemically and/or physically with the hydroxylated surface sites of the silica particles, PA1 and of at least one functionalized organosilane (abbreviated as OS) containing, per molecule, at least one functional group (abbreviated as G1) capable of binding chemically and/or physically with the UN1 units and/or the hydroxylated sites of the silica particles and at least one other functional group (abbreviated as G2) capable of binding chemically and/or physically to the elastomer chains, as silica/elastomer coupling agent in the natural or synthetic elastomer compositions comprising a siliceous material as reinforcing filler intended for the manufacture of an article made of elastomer(s).
