PEROXAN PB-50 P is used for the curing of unsaturated polyester resins at high temperatures. PEROXAN PB-50 P is preferred for the curing of free flowing UP resin based hot press molding formulations (GMC) in the temperature range from 140° to 160°C. Depending on application and working conditions, the following peroxide and when applicable cobalt accelerator dosage levels are recommended: PEROXAN PB-50 P: 2,0 to 4,0 phr

- Product Handling and Storage
- Maximum storage temperature (Ts max) : 30°C
- Minimum storage temperature (Ts min) : 10°C
- Storage stability as from date of delivery : 6 months
- Keep packaging tightly closed in a well ventilated place at indicated storage temperature. Keep away from reducing agents e.g. amines, acids, alkalis, heavy metal compounds (e.g. accelerators, driers, metal soaps). Never weigh out in storage room. Oxidizing agent. Decomposes violently under the influence of heat or by contact with reducing agent. Never mix with accelerators. Organic Peroxides 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.
