Description of key information

Key value for chemical safety assessment

Relative density at 20C:
4.95

Additional information

The relative density of zinc difluoride at 20 °C is 4.95. The relative density D420 is calculated by dividing the density of the test item by the density of water at 4 °C (0.9999750 g/cm³).

The relative density is D420= 4.95.
