Description of key information

Vapour pressure [(1,1,3,3-tetramethyldisiloxane-1,3-diyl)dipropane-1,3-diyl dimethacrylate]: 0.005 Pa at 25°C (QSAR)

Vapour pressure [3-[hydroxy(dimethyl)silyl]propyl methacrylate]: 4.8E-02 Pa at 25°C (QSAR)

Key value for chemical safety assessment

Vapour pressure:
0.005 Pa
at the temperature of:
25 °C

Additional information

A predicted vapour pressure value of 5.0E-03 Pa at 25°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable.

In contact with water, the substance hydrolyses slowly to form 3-[hydroxy(dimethyl)silyl]propyl methacrylate. The vapour pressure of the silanol hydrolysis product was estimated to be 4.8E-02 Pa at 25°C using a validated QSAR estimation method.
