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.
