Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of information:
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: The result was obtained by an appropriate predictive method.
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).
GLP compliance:
other: 25.0°C
kinematic viscosity (in mm²/s)
Viscosity value of 2.3 mm²/s (static) was obtained at 25°C using an accepted calculation method. The result is considered to be reliable.

Description of key information

Viscosity [3 -(2,3 -epoxypropoxy)propyl]triethoxysilane: 2.3 mm²/s (kinematic) at 25°C (QSAR)

Key value for chemical safety assessment

2.3 mm²/s (static)
at the temperature of:
20 °C

Additional information

There are no reliable measured data for the viscosity of the test substance. A predicted kinematic viscosity of 2.3 mm²/s at 25°C was determined for the substance using a validated QSAR estimation method. The result is considered reliable.
