Description of key information

Viscosity (hexamethyldisiloxane): 0.5 mPa.s at 25°C (DIN 51562)

Key value for chemical safety assessment

0.5 mPa · s (dynamic)
at the temperature of:
25 °C

Additional information

A dynamic viscosity value of 0.5 mPa.s at 25°C was determined for the substance in a reliable study conducted according to an appropriate test protocol. No further details are available. This is equivalent to a kinematic viscosity of 0.65 mm2/s based on a density of 0.76 g/cm3.

In secondary sources to which reliability could not be assigned, kinematic viscosity values of 0.65 mm2/s at 15°C and 0.5 mm2/s at 20°C were reported for the substance.
