Description of key information

The closed cup flash point of isophorone diisocyanate oligomer (uretdione type) at atmospheric pressure is reported as 169 °C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
169 °C

Additional information

Since thermal decomposition starts at 80 °C, mainly decomposition products will enable ignition.
