Conclusions:

The dynamic viscosity of SIKA Hardener Lj was determined to be 78.6 mPa*sec at 20 °C and 31.1 mPa*s at 40 °C respectively.

Executive summary:

A study was conducted according to OECD TG 114 to determine the dynamic viscosity of SIKA Hardener LJ. Using the Höppler Viscometer and ultrapure water as reference the viscosity of SIKA Hardener LJ was determined at 20 °C and 40 °C. Two times three replicate measurements were performed at each temperature. The dynamic viscosity of SIKA Hardener LJ was determined to be 78.6 ± 0.002 mPa*s at 20 °C and 31.1 ± 0.003 mPa*s at 40 °C, respectively.
