The test substance is a non-Newtonian fluid between 40 and 60 °C.

Conclusions:
The viscosity of the test substance at 40 °C is 159 300 mPa.s @ 1 s^-1.
The viscosity of the test substance at 60 °C is 8800 mPa.s @ 25 s^-1.
Executive summary:

The viscosity of the test substance was investigated in accordance with the standard ISO 3219 using a rotational viscometer with defined shear rate.

The viscosity of the test substance at 20 °C could not be determined due to the physical properties of the test substance (i.e. it was a solid at this temperature).

The viscosity of the test substance at 40 °C is 159 300 mPa.s @ 1 s^-1.

The viscosity of the test substance at 60 °C is 8800 mPa.s @ 25 s^-1.

The test substance is a non-Newtonian fluid between 40 and 60 °C.
