Thermaguard™ CUI 300

Thermaguard™ CUI 300 is a unique inorganic single component, ambient curing polysiloxane coating formulated specifically to provide corrosion protection to under insulation environments where wet & dry cycling can occur. Novel technology which offers high solids chemistry, low VOC for demanding environmental regulations and safety aspects during hot application. The coating conforms to the NACE SP0198-2017 classification for Corrosion Under Insulation (CUI) in both cryogenic & elevated temperature applications. Through specific formulation technology Thermaguard™ CUI 300 can withstand temperatures from -196 to 300°C, fully curing at ambient conditions eliminating the need for heat curing prior to service. Thermaguard™ CUI 300 has exceptional resistance to thermal cycling, hot saline water immersion & chemical exposure throughout its operating temperature range. Thermaguard™ CUI 300 can be used in both OEM (shop application) & maintenance work due to having surface tolerance to rusted steels, which have been marginally prepared (St 2/3). Additionally, the product can be applied in service to hot equipment operating up to 300°C, removing the need for plant shut down periods.
