contains carbon, hydrogen, nitrogen and oxygen atoms in the chemical configuration CH3NCO.
The materials with low 1,4-butandiol content have long ester chains whereas those with high butandiol contents will contain several isocyanate
groups clustered into a block structure, reflected in the original Mooney plots Fig.

This study sets out to assess the hazard to personnel exposed to isocyanates
during brush/roller painting with isocyanate
paints by the following means (Fig.
DATA SYNTHESIS: Isocyanate
production and use continues to increase as the polyurethane industry expands.
This was achieved by increasing the isocyanate
index values up to 150-250 in PUF compositions.
The new product, Karenz BEI, has one isocyanate
group and two acrylic groups in one molecule, ensuring higher photo-setting speed.
We witnessed violent expansion of feedstock capacity in isocyanate
and polyol markets.
Two teams of astronomers have harnessed the power of the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to detect the prebiotic complex organic molecule methyl isocyanate
 in the multiple star system IRAS 16293-2422.
In the concerted mechanism, the addition of alcohol is carried out across the N=C bond of isocyanate
and immediately results in the product (Scheme la).
are essential raw materials for the production of FPF products.
Polyurethane foam technology consists on foam building by reacting two chemicals, isocyanate
and polyol, in the presence of other additives such as blowing agents, catalysts, and fire retardants.
