Toluene diisocyanate is an organic compound with the formula CH2C6H3(NCO)2. They are used to produce polyurethane foams for insulation, packaging and furniture. They are also used to make adhesives, sealants and polyurethane coatings for metal products and leather. Properties Toluene diisocyanates exist at room temperature as a clear, colorless to pale-yellow liquid with a pungent odor. Other, smaller uses are for polyurethane elastomers (for automobile bumper covers, industrial rollers, sport soles and boots, and mechanical goods) and coatings (for automotive refinishing, wood finishes, and high-performance anti-corrosion coatings) (ICIS 2009). Toluene diisocyanate–based rigid polyurethane foam is used in household refrigerators and for residential sheathing or commercial roofing in board or laminate form "Pour-inplace" or "spray-in" rigid foam is used as insulation for truck trailers, railroad freight cars and cargo containers.
