Application
Trigonox® V388 VR is general purpose methyl ethyl ketone peroxide (MEKP) for the curing of unsaturated polyester resinsin the presence of a cobalt accelerator at room and elevated temperatures. The curing system Trigonox® V388 VR/cobaltaccelerator is developed for general purpose GRP- and non GRP-applications such as the curing of laminating resins andcastings. For room temperature application it is necessary to use Trigonox® V388 VR together with a cobalt accelerator(e.g. Accelerator™ NL-49PN). The vanishing red (VR) series of products include a red indicator system that disappearsduring the cure. The red color is only visible when needed but not in the finished end product. The key features are:indicates initiator presence, monitoring of the mixing step, monitoring of the cure by color and indicating under-curedarea's in the mold, and last but not least it leaves the end product colorless after the cure.Organic Peroxide Team contact us.jpg
