Remark:The flash point was determined at 110.0 °C during the preliminary test and 111.0 °C during the main test. Due to safety reasons, the value of 110.0 °C was retained and was considered to be the flash point value of the test item.
Conclusion
The flash point of the test item was 110.0°C ± 1.0°C (corrected value).
Description of key information
[3-(trimethoxysilyl)propyl]urea: 110°C at 1013 hPa (measured)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 110 °C
Additional information
A flash point value of 110°C (1013 hPa) was determined by equilibrium closed cup method according to EU Method A.9.
