Special purpose catalyst (including vanishing red cure indicator) used for curing tooling gel coats and promoted unsaturated polyester resins in warmer climates. Low-hydrogen peroxide content reduces gelcoat porosity and provides improved curing of vinylester resins. CAS number: 1338-23-4 EINECS/ELINCS No.: 215-661-2 Applications: Cadox L-30a VR can be used in place of Cadox L-50a or Cadox L-50a VR wherever a more dilute solution of methyl ethyl ketone peroxide (MEKP) is desired. Cadox L-30a VR is a special purpose ‘summer catalyst’ for use in warmer shop environments. Cadox L-30a VR offers all the advantages of a red MEKP, except red parts. The 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. Visualize Hot & Cold Spots, Shrinkage Problems, Mass Effects, Thermal Effects of Core Materials and Dead Flow Zones in applications like Vacuum Infusion. Information provided by Nouryon |
