Conclusions:
The flash point of Sika Hardener MH was determined to be 148.5 °C.
Executive summary:

The determination of the flash point of Sika Hardener MH was performed according to EU Method A.9, OPPTS 830.6315 and UN Manual Test Methods 32.4. Three independent determinations were performed. The maximum variation was 3 K. Therefore, the lowest two values (which showed a variation of 2 K) were used for calculation of the mean. The flash point of Sika Hardener MH was determined to be148.5 °C.
