Storage Due to the relatively unstable nature of organic peroxides a loss of quality can be detected over a period of time. To minimize the loss of quality, AkzoNobel recommends a maximum storage temperature (Ts max.) for each organic peroxide product.
For Butanox M-50a Ts max. = 25°C
When stored under these recommended storage conditions Butanox M-50a will remain within the AkzoNobel specifications for a period of at least 3 months after delivery.
Thermal stability Organic peroxides are thermally unstable substances, which may
undergo self-accelerating decomposition. The lowest temperature at
which self-accelerating decomposition of a substance in the original packaging may occur is the Self-Accelerating Decomposition Temperature (SADT). The SADT is determined on the basis of the Heat Accumulation Storage Test.
For Butanox M-50a SADT : 60°C
The Heat Accumulation Storage Test is a recognized test method for the determination of the SADT of organic peroxides (see Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria - United Nations, New York and Geneva).
Carbon dioxide, Water, Acetic acid, Formic acid, Propionic acid, Methyl ethyl ketone
Safety and handling Keep containers tightly closed. Store and handle Butanox M-50a in a dry well-ventilated place away from sources of heat or ignition and direct sunlight. Never weigh out in the storage room. Avoid contact with reducing agents (e.g. amines), acids, alkalis and heavy metal compounds (e.g. accelerators, driers and metal soaps).Please refer to the Safety Data Sheet (SDS) for further information on the safe storage, use and handling of Butanox M-50a. This information should be thoroughly reviewed prior to acceptance of this product. The SDS is available at www.akzonobel.com/polymer.
Applications Butanox M-50a is a multipurpose catalyst for the room temperature cure of promoted unsaturated polyester resins. Unpromoted unsaturated polyester resins can be heat-cured with Butanox M-50a in the temperature range of 100-127°C.Butanox M-50a VR also has a high MEKP monomer content which may provide faster gel times in some resin systems.
