Abstract
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° C. preferably from 50 to 90° 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.
