| Butanox L-50 VR is an ideal catalyst used for curing promoted unsaturated polyester resins at room temperature. Butanox L-50 VR includes a vanishing red indicator system that in most cases virtually disappears during cure. CAS number: 1338-23-4 EINECS/ELINCS No.: 215-661-2 Applications: Butanox L-50 VR is a general purpose methyl ethyl ketone peroxide (MEKP) for room and elevated temperature cure of unsaturated polyester resins in the presence of a metal (Cobalt) accelerator. Butanox L-50 VR has a low hydrogen peroxide content which reduces gel coat porosity and provides improved curing of vinyl ester resins. Butanox L-50 VR offers all the advantages of a standard MEKP like Butanox L-50 with the advantage of a vanishing red indicator system that virtually disappears during cure. The red color is there when you need it in the mixing and application steps but will disappear during cure. Information provided by Nouryon |
