ca. 101 325 Pa

Description of key information

The substance consist of tetrahydrossimethil silane 2.7% stabilized with PEG present at 50.1%, the remaining part is water at 44%.

Based on the high concentration of PEG (> 50%), it can be considered that the phys chem properties of PEG are taken as reference to establish the phys chem properties of the substance as whole, stabilized with PEG.

Melting point of the silicates...are provided as reference.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-10.4 °C
