Galvanic and crevice corrosion to the end covers of the heat exchangers was resulting in leaking around the titanium plates and loss of efficiency.



Belzona® 1341 (Supermetalglide)

Belzona® 9411 (Release Agent)



Carbon steel


Application Method:

Using a modified version of Belzona Know-How System Leaflet GSS-9, a plate is coated with Belzona® 9411 and used to form a thick layer of Belzona 1341 on the end cover. This procedure provides a perfect finish and excellent seal.
