Flange, valve and welded-joint corrosion costs clients millions annually and the complex geometry of flanges
prevents effective surface preparation and coating which can lead to frozen nuts and bolts, weakened weld
joints, and loss of containment. Zerust TFS is a transparent UV-resistant film with proven Vapor Corrosion Inhibitors
(VCIs) for corrosion protection up to four years, even in severe outdoor exposure.


Zerust TFS is available in sizes compatible with international standards.
