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.

SADT: Emergency temperature: Control temperature: |
35°C 25°C 20°C |
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 PO
Peroxyester / Polymerization / Curing / Crosslinking
Polymerization of ethylene:
PEROXAN PO is used for high pressure polymerization of ethylene in both autoclave and tubular processes, usually in combination with other peroxides of varying degrees of activity.
Temperature range: 180 to 230°C
Light-off temperature at 2300 bar: 188°C
Polymerization of styrene:
PEROXAN PO may be used in polymerization and copolymarization of styrene.
Temperature range: 80 to 110°C
Dosing: 0,08 to 0,4 phr
Polymerization of acrylates and methacrylates:
PEROXAN PO can be used as initiator for the solution, bulk and suspension (co)polymerization of acrylates and methacrylates.
Temperature range (solution polym.): 80 to 150°C
Dosing: 0,1 to 1 phr
Other applications:
PEROXAN PO may also be used for the (co)polymerization of acrylonitrile.
PEROXAN PO is used for the curing of unsaturated polyester resins at high temperatures.
PEROXAN PO is preferred for the curing of UP resin based hot press moulding formulations in the temperature range from 100° to 140°C. As PEROXAN PO is a high reactive peroxide, it is very suitable as a kicker in formulations for pultrusion and SMC/BMC.
In combination with a cobalt accelerator e.g. PERGAQUICK C12 X (Cobalt, 1%), PEROXAN PO is applicable for the cure of UP resins in the temperature range of 60°C and higher.
PEROXAN PO has normally a much shorter pot life in the pure resin than PEROXAN PB, tert-Butyl peroxybenzoate.
Depending on application and working conditions, the following peroxide and when applicable cobalt accelerator dosage levels are recommended:
PEROXAN PO: 1,0 to 2,0 phr
PERGAQUICK C12 X (Cobalt, 1%): 0,5 to 3,0 phr
Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN PO. 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.
