PEROXAN PB-75
Peroxyester / Polymerization / Curing / Crosslinking
PEROXAN PB-75 is used for the curing of unsaturated polyester resins at high temperatures.
PEROXAN PB-75 is often times used in combination with a high reactive peroxide like PEROXAN BCC or PEROXAN MI-60 K as kicker in in formulations für pultrusion processes in the temperature range of 100° to 140°C.
In combination with a cobalt accelerator e.g. PERGAQUICK C100 (10% cobalt), PEROXAN PB-75 is applicable for the cure of UP resins in the temperature range of 70°C and higher.
Depending on application and working conditions, the following peroxide and when applicable cobalt accelerator dosage levels are recommended:
PEROXAN PB: 1,3 to 2,3 phr
PERGAQUICK C100 0,1 to 0,6 phr
Please refer to the material safety data sheet (MSDS) for information concerning safe storage, use and handling of PEROXAN PB-75. 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.
