Modified version of Belzona Know-How System Leaflet TCC-5.
As the damage to the vessel was well defined, only the bottom portion of the vessel was treated. Careful surface preparation was implemented as the microbiological impact over the metal was extensive. Detection tests to confirm microorganisms made it a necessity to carefully clean and prepare the metal surface. Ultimately, the Belzona® 1121 was used to rebuild the corroded areas, followed by Belzona® 5891 as the coating material.
