For Repair and Prevention of
Corrosion Under Insulation (CUI)
1251/5851
HA-METAL/HA-BARRIER
Corrosion Under Insulation (CUI) costs
industry a fortune every year in lost
production and repairs. This type of
corrosion can cause failures in areas not
normally of primary concern. The failures,
often the result of localized corrosion, can
be catastrophic in nature or at the very
least have a serious economic effect in
terms of downtime and repair.
CUI is difficult to detect because the
INSULATED INSTALLATION APPEARS SOUND . . . UNDERNEATH - THE REALITY
insulation cover masks the problem.
Whenever CUI is identified through in-
spection techniques such as Ultrasonics,
Infra-red, Radiography or simply visual
inspection after removing the insulation,
the corrosion found requires treatment.
Belzona® 1251 and Belzona® 5851 have
been developed specifically to repair and
protect metal surfaces suffering CUI

without interruption to the plant
operation as they are designed for
application directly onto hot surfaces
(70-150°C/158-302°F).
Both products are single component,
heat activated and solvent free. They only
begin to react and solidify at temperatures
above 70°C (158°F). In addition they are
extremely tolerant of less than thoroughly
