Reference
Results are presented in the attached document "Figures and Tables - Viscosity.pdf".
There was no significant time dependence for the viscosity (Figures 1 and 2).
At both temperatures, the test item showed insignificant decrease in viscosity with increasing spindle speed (shear rate) (Figures 3 and 4 and Tables 1 and 2). This type of behaviour indicates that the test item is a Newtonian fluid.
Description of key information
54000 mPa.s at 20 °C and 8000 mPa.s at 40 °C (OECD114)
