Trigonox 42PR是一种过氧化物配方,基于叔丁基过氧-3,5,5-三甲基己酸酯。Trigonox 42公关has been developed for the cure of unsaturated polyester resins in combination with a cobalt accelerator in the temperature range of 60°C and higher. Trigonox 42PR plus a cobalt accelerator can effectively be used as a match for Trigonox 21 in those areas where the use of Trigonox 21 is restricted by its official transport and storage temperature of max. +20°C. Application area for the cure system Trigonox 42PR plus a cobalt accelerator (e.g. Accelerator NL-53N, 10% cobalt) can be e.g.: artificial marble, polymer concrete, filament winding, air drying lacquers. The combination Trigonox 42PR plus a cobalt accelerator and possibly an amine accelerator like Accelerator NL-63-100 (N,N-Dimethylaniline) is also very suitable for the ambient temperature cure of vinylester resins. Trigonox 42PR gives in these resins a much faster cure than the commonly applied peroxides Butanox LPT and Trigonox 239.
