Corrosion Under Insulation (CUI) coatings are specialized protective systems designed for insulated equipment exposed to moisture and elevated temperatures. These include two component high build phenolic epoxy coatings suitable as heat resistant systems under insulation up to 230°C, one-component high build heat resistant inert multipolymeric matrix / inorganic ceramic coatings, and one component proprietary waterborne liquid insulation coatings providing thermal resistance and personal protection up to 177°C.
