TMI Coatings, Inc. (TMI) recently repaired the existing sprayed-in-place urethane foam insulation and coating on a horizontal CO2 tank that previously had tank insulation. The coating attached to the spray foam insulation was blistered in many areas. Some of the foam insulation had deteriorated and disbonded from the tank; plus, there were some areas where the foam insulation was saturated from condensation. TMI removed the affected foam insulation, prepared the steel surface, reinsulated voids, and applied a new vapor barrier to prevent water vapor condensing on the insulation of the CO2 tank. TMI applied an intermediate and a final topcoat.
