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
- Conclusions:
- 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.
