Description of key information

Density: 1.04 g/cm3 at 20°C (DIN 51757)

Key value for chemical safety assessment

Additional information

The registrant intends to perform a new density study for 3-trimethoxysilylpropyl methacrylate (CAS 2530-85-0). The results will be added to the dossier and updated through voluntary update when the study becomes available.


 


Density values of 1.045 g/cm3 at 25°C and 1.04 g/cmat 20°C, and a relative density value of 1.045 at 25°C, were reported in secondary sources. The value at 20°C was reported to be conducted using DIN 51757 test method. The results are used as weight of evidence in the interim, until the new study is available.
