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 BCC-40 W
Peroxydicarbonate / Polymerization / Curing / Crosslinking
Polymerization of vinylchloride:
PEROXAN BCC-40 W may be used in polymerization and copolymerization of vinylchloride in mass or suspension processes, usually in combination with other peroxides of varying degrees of activity to increase reactor efficiency.
Reasons to use a water based peroxide suspension are the following:
- Enhanced safety
- Solvent free. No contamination of the VCM recycle stream
- Enhancement of PVC purity
- Easy to use (pumpable) in "closed reactor technology"
- Easy to dilute with water
PEROXAN BCC-40 W is especially suitable for the production of micro-S-PVC.
Temperature range: 40 to 65°C
Dosing: 0,08 to 0,4 phr
Other applications:
PEROXAN BCC-40 W may also be used for the (co)polymerization of vinylidenechloride.
PEROXAN BCC-40 W is used for the curing of highly filled methacrylic resins, typically in combination with other curing agents of different reactivity, e.g. PEROXAN LP and PEROXAN PB.
PEROXAN BCC-40 W shows a high reactivity at elevated temperature, which is demonstrated by its low activation temperature, in combination with a relatively long pot life at ambient temperatures.
PEROXAN BCC-40 W is used in combination with a low reactive peroxide to ensure a good final cure. These peroxide combinations can successfully be used for those applications where a long gel time is required at room temperature in combination with a fast cure at elevated temperatures of 60°C to 140°C.
Applications areas can be cure-in-place-pipe (CIPP), pultrusion, filament winding, manufacturing of artificial marble.
Depending on working conditions, the following dosage level is recommended:
PEROXAN BCC-40 W as such: 2,0 to 4,0 phr
PEROXAN BCC-40 W as kicker peroxide: 1,0 to 2,0 phr
25kg container
900kg IBC
Bulk delivery of PEROXAN BCC-40 W in a 1,00 m³ plastic intermediate bulk container (IBC) is possible in a number of countries.
Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN BCC-40 W. 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.
