Main Study

The DSC curve obtained with Experiment 1 is shown in Figure 2. During cooling, no effects were observed which were due to crystallization of the test item (results are archived in the raw data). During heating, an endothermic peak was observed starting at 100°C. The endothermic effect was most likely obtained due to evaporation of volatile components (i.e. solvent) of the test item. After the experiment, a yellowish residue remained in the sample container.

A higher end temperature was applied in Experiment 2 to determine reaction and/or decomposition of the resin part of the test item. Figure 3shows the DSC curve obtained. During heating, similar results as in Experiment 1 were obtained. During heating, an endothermic peak was observed between 75°C and 200°C. This endothermic effect was due to evaporation of volatile components (i.e. solvent). An exothermic peak was observed between 250°C and 373°C. After the experiment, an orange/brown residue remained in the sample container. The exothermic effect was, therefore, considered due to reaction and/or decomposition of the test item. 

An additional investigation of the melting temperature of the test item was performed placing two subsamples of the test item for 72 hours at -19.3 ± 0.5°C and at -80.4 ± 1.1°C respectively. It was observed after storage that the test item was a viscous liquid (≤ ‑15°C freezer) and a very viscous liquid (≤ -75°C freezer). According to this it was concluded that the melting temperature of the test item is < -80°C (< 193K).

Conclusions:

Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.

Executive summary:

The boiling temperature of Setalux 7002 BX-55 were tested by DSC. Reaction and/or decomposition of the test item was observed during DSC experiments at temperatures of > 250°C (> 523K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
