Additional information

The dynamic viscosity at 20 °C and at 40 °C of the substance 2,4,6-triisopropyl-m-phenylene diisocyanate was investigated in a GLP study according to OECD guideline 114 (2011) by using a using a cone/plate-rheometer. The dynamic viscosity has been determined to be 59.35 ± 0.37 mPa s at 20 °C and 19.82 ± 0.05 mPa s at 40 °C. Further, the kinematic viscosity at 20 °C of the substance 2,4,6-triisopropyl-m-phenylene diisocyanate has been determined to be 59.09 mm2/s in a non-GLP study according to ASTM D 7042 (which is equivalent to ISO 3104 / ASTM D445) with a rotational viscometer.
