Isocyanate is the functional group of atoms –N=C=O (1 nitrogen, 1 carbon, 1 oxygen), not to be confused with the cyanate functional group which is arranged as –O–C≡N or with isocyanide, R-N≡C. Any organic compound which contains an isocyanate group may also be referred to in brief as an isocyanate. An isocyanate may have more than one isocyanate group. An isocyanate that has two isocyanate groups is known as a diisocyanate. Diisocyanates are manufactured for reactions with polyols in the production of polyurethanes. The largest use of isocyanates in industry involves the production of polymers. Polymers of common isocyanates are used in the manufacture of foams, paints, lacquers and in electrical insulation.
