Trigonox® 239 is a promoted cumyl hydroperoxide: best cure system for vinylester resins.

Chemical Family Organic peroxide

Physical Form Liquid

Brand Trigonox®

Trigonox® 239 is a peroxide mixture based on cumene hydroperoxide. Trigonox® 239 is especially developed for the cure of vinylester or phenacryl resins in combination with a cobalt accelerator. Trigonox® 239 can successfully be used instead of generally applied keton peroxides like Butanox LPT with the following features: no ‘gassing’ after the peroxide is mixed in the preaccelerated vinylester resin. This phenomenon is very often recognized as a disadvantage of ketone peroxides in vinylester resins. The use of an amine accelerator is in general not necessary to achieve a good cure, a fast cure in thin coatings and laminates up to a thickness of approx. 6 mm and a low peak exotherm in thick laminates.
