Perovion MEKP-CHP L24
Perovion MEKP-CHP L24 is a peroxide blend specially developed for curing unsaturated polyester and vinyl ester resins under ambient conditions in conjunction with a metal accelerator. It can also be used independently for curing unsaturated polyester resins at elevated temperatures. With its balanced reactivity profile and lower exotherm compared with standard MEKP systems, Perovion MEKP-CHP L24 is suitable for demanding composite production environments, especially in warm and hot climate conditions….
