Cortec's Solutions Successfully Combat Internal Corrosion in Marine Structures

Vapor phase corrosion inhibitors from Cortec can protect steel floats and offshore caissons from corrosion attack.

The corrosion inhibitors manufacturer Cortec® Corporation has recently presented a method for combating internal corrosion in marine structures, offering effective protection for floating docks, pontoons, pilings and offshore platform caisson legs. These structures, which are constantly exposed to damp and high-chloride environments, are particularly vulnerable to rusting from the inside out.

The Vapor phase Corrosion Inhibitors (VpCIs) from Cortec provide a unique and efficient solution. Unlike traditional coatings, VpCIs can be applied inside enclosed spaces, forming a hydrophobic molecular layer that prevents corrosion on metal surfaces. So, their self-applying nature allows them to disperse within the structure by vapor diffusion, similar to how an air freshener fills a room - thus protecting both above and below any residual water collected in the structure as well as offering comprehensive protection even in challenging environments.

The VpCIs are easy to apply, whether fogged into voids in liquid or powder form or through breathable pouches that contain the VpCI powder. The solutions from Cortec dramatically reduce corrosion rates, such as for cylinder dock floats, which were found corrosion-free after nine months of VpCI-609 powder treatment. Moreover, offshore platform caissons treated with a combination of VpCI-337 BD and VpCI-609 S, along with EcoPouch® strips, showed significantly lower corrosion rates after two years compared to untreated control structures.
