Description of key information

No data are available for the viscosity of tetramethylsilane.

Key value for chemical safety assessment

Additional information

The requirement to test is waived because the substance is highly volatile (boiling point 27°C, vapour pressure at 20°C 79500 Pa) and is most commonly used in the vapour phase. The liquid viscosity at standard temperature will be low, and viscosity is not relevant when used in the vapour phase.
