The resins include standard orthophthalic and isophthalic resins but also epoxy based vinylester resins for enhanced chemical resistance.
The curing system for the hand lay-up application is most of the time based on a standard MEKP which is supplied under our brand names Butanox® M-50 and Butanox M-60.
For a similar geltime but a faster cure and higher peak exotherm you can choose a standard AAP which is sold as Trigonox® 44B. In order have a faster cure but to avoid too high peak exotherms you can consider for example Trigonox 51 which contains a peak suppressing additive.
In order to reach curing characteristics in-between standard MEKP and AAP we offer a range of specialty peroxides with various compositions. The most common grades are Trigonox 61, Trigonox 63 and Trigonox 65. For a more gradual cure we recommend the use of Cyclonox® LE-50.
