Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Executive summary:

Method


The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.


 


Result


Between 119 - 163 °C, there is a negative peak associated to the release of water/ solvent, followed by a degradation that begins at 320 °C.

Description of key information

The substance decomposes before melting/boiling, starting from 320 °C 

Key value for chemical safety assessment

Additional information

Based on the results of DSC analysis on the analogous , the substance is expected as not melting up to 300 °C but decomposing before at 320 °C.
