  • Applications

    Trigonox 77C is a peroxide mixture, which is used for the curing of unsaturated polyester resins at elevated temperatures.Trigonox 77C can be used instead of Trigonox C for the curing of UP resin based hot press moulding formulations (SMC, BMC etc.) and electro insulation lacquers in the temperature range of 100  170°C.Trigonox 77C is not, or much less, sensitive for reducing agents like metals, metal based pigments, fillers or amines than peresters like Trigonox C. The stability at ambient temperatures of hot press moulding formulations or electro insulation lacquers initiated with Trigonox 77C is therefor much longer than those initiated with a perester like Trigonox C.Trigonox 77C shows at elevated temperatures a comparable reactivity as Trigonox C. The reactivity of Trigonox 77C cannot be increased by the addition of a cobalt accelerator.
