Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Physical state: Liquid
- Stability under test conditions: stable
- Storage condition of test material: In refrigerator in the dark

Results and discussion

Any other information on results incl. tables

In a duplicate experiment it was found that NIKKOL VC-IP has no defined freezing point or freezing range. With decrease of temperature, the viscosity of NIKKOL VC-IP increased, without showing a clear phase transition of the liquid into the solid state.

At a temperature of -42°C (231 K) in test 1 and test 2, the test substance became somewhat cloudy.

At a temperature of -61°C (212 K) in test 1 and at -60°C (213 K) in test 2, an in the test substance inserted stirrer could not be moved.

Applicant's summary and conclusion

In conclusion, no freezing temperature of NIKKOL VC-IP can be determined. The viscosity of the test substance increases with decreasing
temperature, until finally, the test substance is completely solid.
