Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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.
