  • Applications

    Cadox M-50a DVR is a special purpose catalyst for the room temperature cure of promoted unsaturated polyester resins. Unpromoted unsaturated polyester resins can be heat-cured with Cadox M-50a DVR in the temperature range of 100-127°C. Cadox M-50a DVR also has a high MEKP monomer content which may provide reduced cure times in some resin systems. Cadox M-50a DVR offers all the advantages of a red MEKP, except red parts. The DVR series of products includes a stronger VR red indicator system that virtually disappears during cure. The red is there when you need it, but not in the finished product. Visualize hot & cold spots, schrinkage problems, mass effects, thermal effects of core materials and dead flow zones in applications like vacuum infusion.
