    Trigonox 178 VR is a convenient pre-blended initiator suitable for curing unsaturated polyester, vinyl ester and acrylic thermosetting resins at ambient conditions in conjunction with a metal salt. Trigonox 178 VR produces lower exotherms than standard MEKP’s and is useful in warm and hot weather climates. Applications include cast polymer and laminates.Trigonox 178 VR offers all the advantages of a red MEKP, except red parts. The vanishing red (VR) series of products includes a red indicator system that virtually disappears during cure. The red is there when you need it, but not in the finished product.
