measuring the airborne concentrations of incompletely cured isocyanates
in the form of oligomers (aerosol) and isocyanate
monomer (vapor) when removing recently cured paint by light abrasion (manual sanding).
We have been active in the field of isocyanate
research and have collected > 800 published and unpublished articles and documents from 1951 to the present; these articles and documents are related to isocyanates
and span many disciplines.
1) that the PUF polymer matrix has absorption bands at 2135 and 2275 [cm.sup.-1], which are typical of carbodiimide and isocyanate
groups, respectively .
business falls in the category of "individualized products," consisting of Karenz MOI, Karenz AOI and the newly developed Karenz BEI.
For p-phenylene diamine this is essentially correct, since isocyanates
do not form until the reaction is heated.
Short term exposure: Exposure to methylene bisphenyl isocyanate
may make a person allergic to it and produce wheezing, shortness of breath, and coughing.
In Table 3, the comparison between HDI, 2,4-TDI and 2,4-MDI results show that larger isocyanate
molecules lead to lower enthalpies of reaction.

The advantages of improved work hygiene due to the minimized isocyanate
content are particularly evident during this overhaul of wind turbines or during repair work on the rotor blades.
Figure 1 shows schematically the nature of the variable coating thicknesses of isocyanate
on metal surfaces (Shimizu 2011).
Spray Polyurea Elastomers: Aromatic Isocyanate
to Remain Preferred Raw Material Aromatic Isocyanate
is envisaged to persist as preferred raw material for spray polyurea elastomers in light of their poly-functional characteristics.
Technical experts from the Lanxess Urethane Systems business unit will present the latest developments on low free (LF) isocyanate
urethane systems for adhesives, sealants, and one component foams (OCF) at an upcoming event.
