Hydrogen sulfide, for example, reacts with four molecules of FOOF to give sulfur hexafluoride, 2 molecules of HF and four oxygens. . .and 433 kcal, which is the kind of every-man-for-himself exotherm that you want to avoid at all cost.

Its lower exotherm also makes it ideal for casting and potting in cross-section thicknesses of over 1in.
It has an unusually low viscosity of 700-800 cps and an exceptionally low exotherm to a peak of 49°C.
A new two part epoxy features optical clarity, flexibility and exceptionally low exotherm for large casting Applications Master Bond Inc, Hackensack, NJ has developed a new easy to use two component epoxy adhesive for high performance bonding applications called EP30.
As measured using DSC, the material ignites and reacts vigorously at a temperature of approximately 430 °C, with a rather narrow exotherm, matching fairly closely an independent observation on a known super-thermite sample.
However, in the case presented in Figure 6, no concomitant second exotherm was detected in association with the gut freezing.
The individual froze at − 3. 0°C, and the gut froze 67.6 s after the initiation of freezing; inset shows exotherm from this individual, note the lack of a double exotherm.
Ice formation was readily observed in the freezing larvae as a change in the appearance of the image that coincided with the onset of the exotherm.
Example of thermal effect of synchrotron x-ray beam (inset, beam being switched on and off marked with arrows) and exotherm detected from freezing of a
