Trigonox 239C is a peroxide mixture based on cumyl hydroperoxide, tert-butyl peroxybenzoate and Promotor, especially developed to improve the efficiency curing of vinylester resins in combination with a cobalt accelerator. CAS number: 80-15-9; 614-45-9 EINECS/ELINCS No: 210-254-7; 210-382-2 Applications: Trigonox 239C is a peroxide mixture based on promoted cumene hydroperoxide and tert-butyl peroxybenzoate. Trigonox 239C is especially developed to improve the cure efficiency of vinylester resins in combination with a cobalt accelerator at elevated temperatures. An application of use can be filament winding. In this application Trigonox 239C can successfully be used instead of generally peroxides like Trigonox 239 and Butanox LPT-IN with the features of no gassing and an improved cure efficiency.
