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.

PEROXAN PK122 V-80
Peroxyketale / Polymerization / Curing / Crosslinking
Polymerization of styrene:
PEROXAN PK122 V-80 may be used in bulk polymerization of styrene. Due to the bifunctionality of PEROXAN PK122 V-80 and the more constant reaction rate using this initiator, the resulting polymer has a higher molecular weight and shows reduced dispersity.
Temperature range: 90 to 120°C
Dosing: 0,01 to 0,08 phr
Polymerization of acrylates and methacrylates:
PEROXAN PK122 V-80 can be used as initiator for the solution, bulk and Suspension (co)polymerization of acrylates and methacrylates.
Temperature range: 95 to 125°C
Dosing: 0,08 to 0,8 phr
Other applications:
PEROXAN PK122 V-80 may also be used for the (co)polymerization of acrylonitrile.
PEROXAN PK122 V-80 is used for the curing of unsaturated polyester resins at elevated temperatures.
PEROXAN PK122 V-80 is preferred for the curing of UP resin based hot press moulding 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 PK122 V-80 is therefore very suitable for pigmented and non-pigmented hot press moulding formulations where a long shelf life of the compound is required.
Depending on working conditions, the following peroxide dosage level is recommended:
PEROXAN PK122 V-80: 1,5 to 2,5 phr
