Recommended Applications: PEROXAN AZDN can be used for bulk, solution, suspension and emulsion polymerization of styrene, vinylchloride, vinylidenechloride, acrylonitrile, acrylates and methacrylates. PEROXAN AZDN does not form oxygenated residues and does not cause oxidative degradation of pigmented or dyed polymer systems. For this reason, the color stability of transparent, dyed polymers is improved. In acrylic paint manufacture, excessive grafting can be a problem when using peroxides. Because the cyano sec-butyl radical from PEROXAN AZDN shows less tendency to abstract hydrogen from a polymer chain than oxygen centered radicals, PEROXAN AZDN allows the production of resins with a low degree of grafting.

Azo Compounds are more or less stable products but will decompose under the influence of heat. To minimize a loss of quality during storage, it is important that the recommended maximum storage temperature is not exceeded. If a minimum storage temperature is given, an undesirable process such as a solidification or phase separation, is known to occur below this temperature.

Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN AZDN.
