Butanox® M-50 VRL is a general purpose methyl ethyl ketone peroxide (MEKP) for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures.Butanox® M-50 VRL offers all the advantages of a standard MEKP like Butanox® M-50 with a vanishing red indicator system that disappears during cure. The red color is there when you need it during the mixing and application steps but disappears during cure.The curing system of Butanox® M-50 VRL with cobalt accelerator is particularly suitable for the curing, laminating resins, lacquers and castings; moreover the manufacture of non-yellowing parts may be possible contrary to the curing system benzoyl peroxide/amine accelerator. Practical experience throughout many years has proven that due to the low water content and the absence of polar compounds, Butanox® M-50 VRL is very suitable in GRP products for marine applications.
