| Trigonox 249 VRN is a special peroxide blend with a VRN system, suitable for curing unsaturated polyester and vinylester resins at ambient conditions in conjunction with a metal accelerator. Produces lower exotherms than standard MEKP’s and is useful in warm and hot weather climates. Applications include cast polymer and thick laminates. CAS number: 1338-23-4, 80-15-9 EINECS/ELINCS No: 215-661-2; 201-254-7 Applications: Trigonox 249 VRN is a convenient initiator suitable for curing unsaturated polyester, vinyl ester and acrylic thermosetting resins at ambient conditions in conjunction with a metal salt. Trigonox 249 VRN offers the advantages of a standard red peroxide formulation to indicate product flow and proper mixing into the resin. The vanishing red (VR) series of products however 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 mould, and last but not least it leaves the end product colorless after the cure.
