- Executive summary:
The information is taken from the OECD SIDS report 2003. The study for vapour pressure (1998) is rated according to Klimisch as 2, valid with restrictions.
The vapour pressure is <= 0.000045 hPa at 100°C.

Description of key information
Because of the substance structure of dicyandiamide, it can be assumed that the vapour pressure of dicyandiamide
can be neglected. This assumption is supported by the vapout pressure values given the technical report from Degussa (2002) and the OECD SIDS report (2003).
Key value for chemical safety assessment
- Vapour pressure:
- 0 hPa
- at the temperature of:
- 20 °C
Additional information
There are two data sources available (collection of data and OECD SIDS report) indicating that the vapour pressure is negligible low. The technical report states a value of 0.0000085 hPa at 20°C and the OECD SIDS report states a value of 0.000045 hPa at 100°C.
