<p>The invention concerns a plug based on polymers characterised in that it uses a composition or pre-mixture based on volatile corrosion inhibitors comprising in an efficient amount at least a structuring agent consisting of a solid or pasty substance whereof the melting point is between 40 and 110 °C, preferably between 50 and 90 °C. The invention also concerns the use of said plug for internally protecting hollow metal parts against corrosion.</p> |
