Storage stability
The test substance showed a temperature rise of 7 K, at a storage temperature of 150 °C. The maximum was reached after 2.75 hours. Drying at a maximum temperature of 150 °C with a maximum residence time of 120 hours is possible if it is ensured that the temperature of 150 °C can not be exceeded.

Applicant's summary and conclusion
- Conclusions:
- The test substance showed a temperature rise of 7 K, at a storage temperature of 150 °C. The maximum was reached after 2.75 hours. Drying at a maximum temperature of 150 °C with a maximum residence time of 120 hours is possible if it is ensured that the temperature of 150 °C can not be exceeded.
- Executive summary:
Storage stability was assessed in accordance with VDI 2263 Part 1. 400 ml of the substance sample were placed in a wire mesh basket under air flow of 100 l/h.
The sample temperature was measured using two thermocouples (sample center and side). The reference temperature was a thermocouple in the gas space of the furnace. All temperature values were recorded by computer system.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
