Trigonox 77C是一种过氧化物混合物,用于高温下固化不饱和聚酯树脂。Trigonox 77 ccan 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.
