Description of key information

The autoignition temperature of isophorone diisocyanate oligomer (uretdione type) at atmospheric pressure is reported as 460 °C. Since thermal decomposition starts at 80 °C, mainly decomposition products will enable ignition. 

Key value for chemical safety assessment
