Description of key information

The kinematic viscosity of 2,2,4(or 2,4,4)-trimethylhexane-1,6-diisocyanate was determined according to OECD guideline no. 114 (1981) and standard method DIN 51562 – part 1 (1999) with the capillary viscometer method. The result was 4.71 mm2/s at 20 °C.

Key value for chemical safety assessment

4.71 mm²/s (static)
at the temperature of:
20 °C

Additional information

The viscosity may vary with isomer ratio. In view of the structural similarity of the isomers such variations are expected to be low.
