Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Temp.:
40°C
Parameter:
other: dynamic viscosity (Pa*s)
Value:
3.509
Remarks on result:
other: at shear rate D = 0.10
Conclusions:
Dynamic viscosity, measured by rotational viscometer:
- 20 °C : 69.630 +/- 0.379 Pa*s, at shear rate D = 0.10 - 40 °C: 3.509 +/- 0.039 Pa*s, at shear rate D = 0.10
Executive summary:

The viscosity of the substance was tested based on the OECD 114 and in compliance with GLP. Dynamic viscosity measured by rotational viscometer was found to be:

- 20 °C : 69.630 +/- 0.379 Pa*s, at shear rate D = 0.10 <D< 10.0 sec-1

- 40 °C: 3.509 +/- 0.039 Pa*s, at shear rate D = 0.10 <D< 10.0 sec-1
