First determination

-49.6 °C (223.6 K)

-42.6 °C (230.6 K)

Second determination

-49.8 °C (223.4 K)

-42.4 °C (230.8 K)

Conclusions:
SIKA Hardener MH showed a melting range between -49.7 to -42.5 °C.
Executive summary:

The determination of the melting / freezing point of Sika Hardener MH was performed according to OECD Guideline 102 resp. EU Method A.1 resp. OPPTS 830.7200. The determination was performed in duplicate. In both determinations, a melting range was detected. The melting range was determined as -49.7 to -42.5 °C (223.5 to 230.7 K). This value is the mean of two independent determinations.
