No evidence of solidification or freezing of the test material was observed down to a temperature of 253 ± 0.5 K.

Conclusion

The melting/freezing temperature of the test substance has been determined to be less than 253 ± 0.5 K.

Conclusions:

The melting/freezing temperature of 3-(trimethoxysilyl)propyl acrylate was determined to be less than 253 ± 0.5 K (<-20°C) at 1013 hPa using a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Freezing temperature: <253 ± 0.5 K (<-20°C) at 1013 hPa (EU Method A.1)

Additional information

A measured freezing point value of <253±0.5 K at 1013 hPa was determined for the substance using a freezing point method in accordance with EU Method A.1 and in compliance with GLP. The result is considered to be reliable.
