摘要

Disclosed is a device for treating the outer surface of a cork plug (3), including: a first so-called reactive liquid composition including: a so-called bi-epoxyde composition of at least one compound having a molecular mass between 340 g/mol and 800 g/mol; a so called reactive solvent; a so-called curing liquid composition including at least one polyamine adapted for forming a protection film by polymerization at the surface of a cork plug (3); characterized in that the reactive composition includes a load of a solid in the divided state dispersed in the reactive composition, the solid in the divided state including barium sulphate.
