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.

The SADT (Self Accelerating Decomposition Temperature) is the lowest temperature at which a self accelerating decomposition may occur.
The emergency temperature is derived from the SADT. It is the temperature at which emergency actions have to be taken. The control temperature is the maximum temperature at which the product can be transported safely.

PEROXAN HXP
Peroxyester / / Polymerization / Curing / Crosslinking
Polymerization of styrene:
PEROXAN HXP may be used in polymerization and copolymarization of styrene.
Temperature range: 80 to 110°C
Dosing: 0,1 to 0,5 phr
Polymerization of acrylates and methacrylates:
PEROXAN HXP can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates.
Temperature range (solution polym.): 80 to 160°C
Dosing: 0,1 to 1 phr
Other applications:
PEROXAN HXP may also be used for the (co)polymerization of butadiene.
PEROXAN HXP is used for the curing of unsaturated polyester resins at high temperatures.
PEROXAN HXP is preferred for the curing of UP resin based hot press moulding formulations in the temperature range from 120° to 160°C.
PEROXAN HXP is often times used in combination with a low reactive peroxide like PEROXAN PB or PEROXAN BIC and an optimal low profile SMC formulation for the production of HPM parts with a Class A surface at short moulding times.
Depending on working conditions, the following peroxide dosage level is recommended:
PEROXAN HXP as such: 1,0 to 2,0 phr
combined with low reactive peroxide: 0,25 to 1,0 phr
Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN HXP. This information should be thoroughly reviewed prior to acceptance of this product. The MSDS is available for downloading at www.pergan.com or through contacting Pergan directly.
