Third Generation Polysiloxane CUI Coatings and Sprayable Insulation for Hot, Cold and Cyclic Service; Lab Testing and Five Years of Field Experience

Abstract Third Generation Polysiloxane (TGPS) ambient curing CUI mitigation coatings have been used in the petrochemical industry for over five years. These coating technologies have demonstrated positive results in both shop and field application for asset management in elevated temperature, cryogenic and cyclic applications across −196 to 650°C/-321 to 750°F operational temperatures. TGPS coatings have demonstrated effective use of a two-step (primer-insulation) CUI mitigation coating approach operating up to 400° C/750°F, when compared to the traditional (CUI coating-fibrous insulation-cladding) systems.
