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):
0
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.
