CAS number: 1689576-89-3
All substances of the MDI category except the monomeric MDI substances are liquid at room temperature. The kinematic viscosities are broadly consistent due to the presence of a relatively high concentration of mMDI. All the other substances of the MDI category are liquid at room temperature. The kinematic viscosities are broadly consistent due to the presence of a relatively high concentration of mMDI. A supporting study was performed at Chilworth (2014). A new study to determine the viscosity of the substance was performed at Dekra (2019). The test is conducted in accordance with ISO 3104:1994 and OECD Test Guideline 114 and gave the following results:
At 20°C (mean of 2 runs) 1098 Cst; at 40°C (mean of 2 runs) 179 Cst
