PEROXAN PB M-20 is used for the curing of unsaturated polyester resins in combination with a cobalt accelerator e.g. PERGAQUICK C100 in the temperature range of 60°C and higher. PEROXAN PB M-20 plus a cobalt accelerator can effectively be used as a replacement for PEROXAN PO in those areas where the use of PEROXAN PO is restricted by ist official transport and storage temperature of max. 20°C. Applications areas for the cure system PEROXAN PB M-20 plus a cobalt accelerator can be e.g. artificial marble, polymer concrete, etc. The combination PEROXAN PB M-20 plus a cobalt amine accelerator e.g. PERGAQUICK C24 A is very suitable for the ambient temperature cure of vinylester resins. PEROXAN PB M-20 gives a much faster cure in these resins than the commonly applied PEROXAN ME-50 LA or PEROXAN CU-25 M. Depending on application and working conditions, the following peroxide and when applicable cobalt accelerator dosage levels are recommended: PEROXAN PB M-20: 1,0 to 2,0 phr PERGAQUICK C100: 0,1 to 0,5 phr
