Thermaguard™ CUI 650

Color: Light Grey
Size: 10 litre can
Sale price£549.12 inc.VAT


Thermaguard™ CUI 650 is a single component, full ambient cure, Corrosion Under Insulation (CUI) coating for temperatures operating from -196 to 650℃. A third generation polysiloxane coating which eliminates the necessary heat curing process prior to service, previously seen with single component polysiloxane coatings, this is facilitated through a novel single pack, ambient curing mechanism.

Designed to endure degradative environments found under insulation systems in cyclic temperature service. Fully tested against rapid thermal cycling, boiling saline water immersion, corrosion protection (C5 environment), chemical resistance, weathering and hardness in accordance with ISO & ASTM testing standards.

Thermaguard™ CUI 650 is used for cryogenic (-196℃) and high temperature resistant anti-corrosion purposes including specification by majors for CUI mitigation under traditional insulation systems. Both in shop (new build) and maintenance applications such as marginally prepared steels and hot application up to 300℃.
