Description of key information

Not required; exempted by Annex 9. However the stability of the substance dissolved in some organic solvents has been studied. Dissolved in DMSO, TDI isomers are unstable with degradation half life being measured in minutes.   The water content of the DMSO influences the rate of degradation. TDI isomers are relatively stable for several hours in EGDE solvent.
