Storage:
Due to the relative instability of organic peroxides, there will be a certain loss of quality over time. To minimize the loss quality, the maximum storage temperature (maximum storage temperature) is recommended for each organic peroxide. Although the temperature has little effect on the quality of Perkadox PF-DB25, we still recommend storing this product below 25°C to prevent stratification. Before using this product, it should be shaken gently to mix evenly. To prevent product from solidifying, we recommend a minimum storage temperature of -10°C.
Thermal stability organic peroxides are thermally unstable substances that can undergo selfaccelerating decomposition. The self-accelerating decomposition temperature (SADT) is the lowest temperature at which a substance can undergo self-accelerating decomposition in the in which it is used for transport. The SADT is determined by the thermal accumulation storage test. For Perkadox PF-DBM25, SADT 60°C
Fire Protection:
1. This product may decompose violently due to heat and can cause a fierce fire. Small fires should be extingished quickly with foam or dry powder fire extinguishers.
2. In the event of a large fire, evacuate to a safe distance immediately and use a water gun to out the fire, notify the fire department for handling.
