The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The boiling point of Cyclohexane, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethyl-, homopolymer, caprolactam-blocked was determined using the Siwoloboff method according to OECD TG 103 (1995) and EU Guideline A.2 (2008). No boiling point was found. Instead, decomposition started at 254.5 °C under atmospheric pressure (1029 hPa), leading to a viscous material of yellow to brown colour. Bubbles indicated the additional formation of substances that rapidly evaporated under the test conditions.

Key value for chemical safety assessment
