The invention concerns the use of a composition or premix based on volatile corrosion inhibitors comprising, in order to limit to a maximum the release and/or degradation of the volatile corrosion inhibitors when the composition or premix is being formed, either an efficient amount of a structuring agent consisting of at least one solid or pasty substance whereof the melting point ranges from 40 to 110 DEG C, preferably from 50 to 90 DEG C, or a liquid substance capable of forming, mixed with a mineral filler, a solid or pasty combination. The invention also concerns a composition based on volatile corrosion inhibitors comprising a composition based on volatile corrosion inhibitors comprising an efficient amount which contains an efficient amount of a solid structuring agent. The invention further concerns polymer based articles having as constituent said composition or premix; said article are useful for protecting metal parts against corrosion.
L'invention a pour objet l'utilisation d'une composition ou prémélange à base d'inhibiteurs de corrosion volatils qui comporte, pour limiter au maximum la libération et/ou la dégradation des ICV au moment de la formation de la composition ou prémélange, soit une quantité efficace d'un agent structurant constitué par au moins une substance solide ou pâteuse dont le point de fusion est de 40 à 110 °C, de préférence de 50 à 90 °C, soit une substance liquide propre à former, en mélange avec une charge minérale, un ensemble pâteux ou solide. Elle vise également une composition à base d'inhibiteurs de corrosion volatils qui comporte une quantité efficace d'un agent structurant solide. Elle vise en outre des articles à base de polymères dans la constitution desquels entre la susdite composition ou prémélange; ces articles sont utiles pour la protection de pièces métalliques contre la corrosion.
