    Cadox D-50 Red is a special purpose catalyst for the room temperature cure of promoted unsaturated polyester resins. Cadox D-50 Red has a low hydrogen peroxide content which provides improved curing of vinyl ester resins. Cadox D-50 Red also has a high MEKP monomer content which may provide reduced cure times in some resin systems.  Cadox D-50 Red offers all the advantages of a red MEKP. The series of products includes a red indicator system that is there to visualize hot & cold spots, shrinkage problems, mass effects, thermal effects of core materials and dead flow zones in applications like vacuum infusion.
