Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Henry´s law constant was estimated using HENRYWIN v. 3.10 to be 1.3E-12 Pa m3/mol at a temperature of 25 °C. For the calculation tHDI Trimer (Isocyanaurate , n=3) was chosen. 

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
at the temperature of:
25 °C

Additional information

With a vapour pressure of < 0.0001 hPa volatilisation of the substance is unlikely. Since IUCLID does not except a low Henry`s law constant of 1.31E-12 Pa m3/mol it is given as 0.000000001 Pa m3/mol which is the lowest accepted value.
