Trigonox 44B VRN是一种乙酰过氧化丙酮配方,用于在室温和高温下,钴促进剂存在下固化不饱和聚酯树脂。在室温和高温下,使用Trigonox 44B VRN/钴促进剂的固化体系比使用MEKP +钴促进剂的固化体系可以实现更快的固化速度。通常Trigonox 44B VRN的凝胶时间与Butanox M-50相当。Trigonox 44 b VRNis particularly suitable in those applications where a fast mould-turnover is required, e.g. for the cold press moulding or resin injection moulding techniques.The system Trigonox 44B VRN/cobalt accelerator will give a higher peak exotherm than a standard MEKP/cobalt accelerator system. Due to this fact, is it recommendable to avoid the production of too thick laminates in one operation. At low temperatures a reasonable speed of cure is still obtained when Trigonox 44B VRN is used in combination with large amounts of cobalt accelerator possibly in combination with N,NDimethylaniline as promotor.
