Due to the relative instability of organic peroxides, a certain amount of mass loss can occur over time. In order to minimize this loss of quality, AkzoNobel recommends a maximum storage temperature (maximum storage temperature) for each organic peroxide. Although temperature has little effect on the quality of Perkadox PF-DBM25, we recommend storing the product below 25°C to prevent delamination. Before using this product, it should be gently shaken. To prevent solidification, we recommend a minimum storage temperature of -10°C. Thermal Stability Organic peroxides are thermally unstable and can undergo self-accelerating decomposition. The Self-Accelerated Decomposition Temperature (SADT) is the lowest temperature at which a substance is likely to undergo self-accelerated decomposition in the packaging in which it is intended to be transported.The SADT is determined on the basis of a heat accumulation storage test. For Perkadox PF-DBM25 SADT:60°C

Fire protection:

1, the product may be due to heat and violent decomposition, will be violent fire, a small amount of product small fire should be quickly extinguished with foam or dry powder fire extinguisher.

2, the fire should be quickly withdrawn to a safe distance away and use the water gun park rescue, notify the fire department to deal with.
