Thermaguard™ CUI 300

Color: RAL 7035
Size: 10 litre can
Sale price£439.92 inc.VAT


Thermaguard™ CUI 300 is a single component, full ambient cure, Corrosion Under Insulation (CUI) coating for temperatures operating from -196 to 300℃. A third generation polysiloxane coating which eliminates the necessary heat curing process prior to service, previously seen with single component polysiloxane coatings. Fast hardness development (reduced transportation damage) and shop throughput with 2 hour recoating times at 20℃.

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 300 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℃.

  • High build, single component, ambient cure polysiloxane
  • Operating temperature range from -196 to 300℃
  • Novel third generation polysiloxane, fully ambient curing
  • Conforms to NACE SP0198-2017 for CUI coating mitigation
  • Protection against Corrosion Under Insulation (CUI) for carbon and stainless steels
  • Application to hot substrates up to 300℃ (in-situ)
  • Fully tested in laboratory & field applications for CUI service
  • Use as anti-corrosion primer under Thermaguard™ TIC 400 insulation coating
