    Cadox M-50a Red is a special purpose catalyst for the room temperature cure of promoted unsaturated polyester resins. Cadox M-50a Red has a low hydrogen peroxide content which provides improved curing of vinyl ester resins. Cadox M-50a Red also has a high MEKP monomer content which may provide reduced cure times in some resin systems.  Cadox M-50a 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.
