| Special purpose catalyst for curing tooling gel coats and promoted unsaturated polyester resins. Low-hydrogen peroxide & high dimer content reduces gel-coat porosity and provides improved curing of vinylester resins. CAS number: 1338-23-4 EINECS/ELINCS No.: 215-661-2 Applications: Cadox L-50a VR is a special purpose catalyst for the room temperature cure of promoted unsaturated polyester resins. CADOX L-50a VR has a low hydrogen peroxide content which provides improved curing of vinyl ester resins. Cadox L-50a VR also has a high MEKP dimer content which may provide reduced cure times in some resin systems. Cadox L-50a 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, schrinkage problems, mass effects, thermal effects of core materials and dead flow zones in applications like vacuum infusion. Information provided by Nouryon |
