Additional information
There are no reliable measured viscosity data for 2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane. A kinematic viscosity of 6.3 mm²/s at 20°C was determined for the substance using a validated QSAR estimation method. The result is considered to be reliable.
2,4,6,8,10 -Pentamethyl-2,4,6,8,10-pentavinylcyclopentasiloxane Vi5-D5 (CAS No: 17704-22-2; impurity 1) and 2,4,6-trimethyl-2,4,6-trivinylcyclotrisiloxane Vi3-D3 (CAS no: 3901-77-7; impurity 2) may be present as impurities. Predicted kinematic viscosity values of approximately 15 mm2/s and 2.1 mm2/s at 20°C were determined for Vi5 -D5 and Vi3 -D3, respectively using a validated QSAR estimation method.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
