Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2017-04-11
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Qualifier:
according to guideline
Guideline:
ISO 3219 (Plastics; polymers/resins in the liquid state or as emulsions or dispersions; determination of viscosity using a rotational viscometer with defined shear rate)
Principles of method if other than guideline:
The viscosity was measured with a rheometer using the measuring system double concentric cylinders in the shear rate interval 10-100 s-1 at 20 and 40°C. The fluid was Newtonian at the measured temperature and shear rate interval.
GLP compliance:
no
Type of method:
rolling ball viscometer (dynamic)
