Recommended Applications

PEROXAN PK295 P is used for the curing of unsaturated polyester resins at elevated temperatures. PEROXAN PK295 P is preferred for the curing of UP resin based hot press molding formulations in the temperature range from 120° to 170°C. The stability of this peroxyketal in an UP resin is hardly influenced by the presence of metal accelerators, pigments or fillers. PEROXAN PK295 P is therefore very suitable for pigmented and non-pigmented hot press molding formulations where a long shelf life of the compound is required. Depending on working conditions, the following peroxide dosage level is recommended: PEROXAN PK295 P: 2,0 to 3,0 phr

Product Handling and Storage
  • Maximum storage temperature (Ts max) : 30°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.
