Trigonox® V388 VRB is general purpose methyl ethyl ketone peroxide (MEKP) for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. The curing system Trigonox® V388 VRB/cobalt accelerator is developed for general purpose GRP- and non GRP-applications such as the curing of laminating resins and castings. For room temperature application it is necessary to use Trigonox® V388 VRB together with a cobalt accelerator (e.g. Accelerator® NL-49PN). The vanishing red (VR) series of products include a red indicator system that disappears during 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-cured area's in the mold, and last but not least it leaves the end product colorless after the cure.
