at the temperature of:
20 °C

Additional information

The viscosity (dynamic viscosity) of the test susbstance tert-butylperoxyisobutyrate (TBPIB) 75 % in isododecane was examined by an Ubbelohde viscometer in three separate measurements at 20°C. An average of the time measured (the time it takes for the liquid to pass between two marked points) was considered for the viscosity calculation. Thus, the viscosity result obtained for TBPIB 75 % in isododecane was 1.4 mPa.s.
