Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2004-09-20 to 2004-11-03
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 103 (Boiling point/boiling range)
Version / remarks:
1995
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.2 (Boiling Temperature)
Version / remarks:
1992
Deviations:
no
Principles of method if other than guideline:
For the exact determination of the decomposition temperature, an aluminium block was used. The capillary tube containing the test item was set into the block at 260 °C. Using a gas burner, the block was heated (heating rate =< 1 K/min). The temperature was noted at which the first signs of decomposition (change of colour) of the test item could be observed.
GLP compliance:
yes (incl. certificate)
Type of method:
other: Capillary tube method.
Key result
Boiling pt.:
280.5 °C
Atm. press.:
1 013 Pa
Decomposition:
yes
Decomp. temp.:
280.5 °C
Conclusions:
No boiling point could be estimated for Sika Härter LH. The substance starts to decompose at 281 resp. 280 °C.
Executive summary:

For the test item Sika Härter LH no boiling point could be determined according to OECD TG 103 adopted 27 July 1995 and EU method A.2 (31 July 1992). The substance starts decomposition at 281 resp. 280 °C. A calculation with the Banks method resulted in a quick initial estimate of 665 K resp. 392 °C. No structural formula is given, therefore, no boiling point could be calculated according to the adapted Stein and Brown method.

Description of key information

SIKA Hardener LH decomposed at 280.5 °C and 1013 hPa.  

Key value for chemical safety assessment

Additional information

A boiling point study was carried out according to EU guideline A.2 and OECD 103. SIKA Hardener LH decomposed at 280.5 °C and 1013 hPa. A calculation with the Banks method resulted in a quick initial estimate of 665 K resp. 392 °C. No structural formula is given, therefore, no boiling point could be calculated according to the adapted Stein and Brown method.
