Abstract

L'invention concerne une composition de revêtement utile pour protéger les navires et les constructions maritimes des biosalissures, par exemple les bateaux, les bouées, les plates-formes, etc. et notamment leurs parties immergées, en empêchant le dépôt de microorganismes marins (vestimentifères, moules, berniques, algues, etc.) et qui assure une protection longue durée contre les biosalissures en réduisant le dépôt de microorganismes marins (boue bactérienne). Le revêtement est adapté à une application sur des revêtements anticorrosion classiques, ainsi que sur des surfaces métalliques et non métalliques ne nécessitant pas de protection contre la corrosion. La composition de revêtement comprend une combinaison de caoutchoucs siloxane vulcanisables à température ambiante ayant différentes longueurs de chaîne macromoléculaire; une huile ou une combinaison d'huiles qui ne participent pas à la formation de réseaux; une combinaison de charges; un solvant; un agent durcissant et un catalyseur de la réaction de durcissement.
