Additional information

HDI Trimer hydrolyses rapidly at environmental relevant temperatures. The half life of HDI Trimer in an acetonitrile/water solution is 3 to 7.7 hours at ambient temperature.

In the atmosphere the main component HDI Trimer (Isocyanurat, n=3) will be degraded due to indirect photodegradation in about 10 hours. Based on the low adsorption potential in UV-B range, no significant direct photodegradation is expected.
