Methyl
isocyanate 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 [1] 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).
Isocyanates 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.
