Description of key information

The vapour pressure of 2,2,4(or 2,4,4)-trimethylhexane-1,6-diisocyanate was determined according to OECD Guideline 104 (2006) and EU test method A.4 (2008) with the vapour pressure balance at temperatures from 20 to 40 °C (end of method applicability). An Antoine equation was derived. The value at 20 °C is 0.31 Pa.

Key value for chemical safety assessment

Vapour pressure:
0.31 Pa
at the temperature of:
20 °C

Additional information

The vapor pressure of the unpolymerized hydrolysis product 2,2,4(or 2,4,4)-trimethylhexane-1,6-diamine is approx. 0.04 hPa at 20 °C.
