Foamed-in-place polyurethane (FIPP) may be regarded as a composite, three-component material system made up of a metal primer, insulating foam, and a barrier topcoat. This material is excellent hot or cold insulation, is low in cost, and easy to apply. Data and recommendations on cost comparisons, systems design, application, corrosion, atmospheric protection, and fire protection of FIPP systems are presented and analyzed. The major recommendations for the use of FIPP on steel surfaces include: the need for a protective coating on the substrate steel for steel corrosion protection; during application, avoid steel surface temperatures below 80/sup 0/F, ambient temperatures below 65/sup 0/F, and water vapor on the steel surface; a gas barrier elastomeric coating should be applied quickly to the FIPP to prevent weathering damage and should be followed by a highly reflective white coating to limit thermally induced stresses on tank roofs; and low flame spread FIPP formulations and weather coatings should be used to minimize fire hazards.
