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.

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.
