> 200 °C
Conclusions:
Under the study conditions, degradation of the test substance occurs before evaporation and prevents proper determination of the evaporation point.
Executive summary:

A study was conducted to determine the boiling point of the test substance according to OECD Guideline 103 and EU Method A.2. As the resins are liquid at room temperature, evaporation was measured at supra-ambient temperatures using conventional differential scanning calorimetry (DSC). For temperature-sensitive resins such as acrylate resins, polymerization may occur along with or before evaporation and often prevents proper determination of the evaporation point. Under the study conditions, degradation of the test substance occurs before evaporation and prevents proper determination of the evaporation point ( > 200 °C) (Boutreau, 2017).

Description of key information

The boiling point was determined according to OECD Guideline 103 and EU Method A.2 (Boutreau, 2017).

Key value for chemical safety assessment

Additional information
