Description of key information
The kinematic viscosity at 40 °C is < 7 mm²/s according to the SDS. This is confirmed in a study which showed a kinematic viscosity of 1.456 mm²/s at 20 °C and 1,107 mm²/s at 40 °C.
Key value for chemical safety assessment
- Viscosity:
- 1.456 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
