- Conclusions:
- Sika Härter LJ has a melting point of -39.3°C at 1013 hPa.
- Executive summary:
Sika Härter LJ was tested for the melting point in a study according to EU method A.1, respectively OECD Guideline 102. A melting point of -39.3 °C with an estimated accuracy of ± 0.1 °C was determined. The test item showed the typical behaviour of a pure substance with a defined melting point. No observations were made which might cause doubts on the validity of the study outcome. (LAUS, 2004)
Reference
Visual observations: The substance started to melt, forming first little drops, then a liquid with visible specks and smears. Disappearance of visible unmelted parts was recorded as end of melting process.
The following values were recorded:
First determination: Begin: -39.8 °C, End: -39.4 °C, Mean: -39.6 °C
Sec. determination: Begin: -39.6 °C, End: -39.1 °C, Mean: -39.4 °C
Evaluation
The mean of both determinations gives the following value for the melting point:
Melting point: - 39.3°C
Estimated accuracy: ± 0.1°C
Validity
• The values of the single determinations show a difference of 0.25 K. This is within the demanded range of 0.5 K
• A defined melting point could be determined (difference between beginning and end of the melting process ≤ 0.5 K)
Description of key information
Sika Härter LJ has a melting point of -39.3°C at 1013 hPa.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -39.3 °C
