Isocyanate is the functional group with the formula R−N=C=O. Organic compounds that contain an isocyanate group are referred to as isocyanates. An organic compound with two isocyanate groups is known as a diisocyanate. Diisocyanates are manufactured for the production of polyurethanes, a class of polymers.

The use of plastics continues to increase in a wide variety of applications. This growth can be attributed to several key advantages plastics have in comparison to metal, including a decrease in part weight, the ability to form complex parts using low-cost tooling and the lack of corrosion.1 These plastics are often coated to provide improved aesthetics or resistance properties.

Blocked Isocyanate. Blocked isocyanates are reaction products of isocyanates with, for example, phenols, oximes, caprolactam or β-dicarbonyl compounds, which at higher temperature dissociate to reform the original isocyanate group (see equation 8).63–65 Alternatively, the curing agent can be deactivated by complexing.

Isocyanates are compounds containing the isocyanate group (-NCO). They react with compounds containing alcohol (hydroxyl) groups to produce polyurethane polymers, which are components of polyurethane foams, thermoplastic elastomers, spandex fibers, and polyurethane paints. Isocyanates are the raw materials that make up all polyurethane products.

Isocyanates are extremely reactive, especially toward substrates containing active hydrogen. Their reactions typically involve attack at the carbon of the isocyanate (by, for example, water or short-chain mono- or polyhydric alcohols) in a manner similar to that for carboxylic acid derivates such as esters or anhydrides.
