Additional information

A study was conducted according to OECD TG 104, Regulation (EC) No 440/2008 method A.4 and OPPTS 830.7950 to determine the vapour pressure of the test item. The vapour pressure of the test item SIKA Hardener LTJ was determined at four different temperatures (30, 45, 60 and 75 °C) following EU A.4 using the effusion method (weight loss). Experiment 4 (temperature 75 °C) showed clear signs of decomposition and to avoid bias, these measurements were not used for calculations. Three experiments could be evaluated as they showed relevant and reproducible weight loss. All evaluated experiments showed good to medium reproducibility, giving a perfect correlation. Therefore, the result of the test can be considered valid. The vapour pressure of the test item was determined to be 6.64E-4 Pa at 20 °C and 9.93E-4 Pa at 25 °C.
