Butanox M-60 is the work horse in GRP curing systems, with 10% higher active oxygen compared to Butanox M-50. Medium-reactive, general purpose methyl ethyl ketone peroxide (MEKP) with guaranteed low water content, used for curing unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. CAS number: 1338-23-4 EINECS/ELINCS No.: 215-661-2 Applications: Butanox M-50A is a multipurpose catalyst for the room temperature cure of promoted unsaturated Butanox M-60 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-60 is a 10% higher concentrated version of Butanox M-50. The curing system Butanox M-60/cobalt accelerator is particularly suitable for the curing of gelcoat resins, laminating resins, lacquers and castings; moreover the manufacture of light resistant parts may be possible contrary to the curing system benzoyl peroxide/amine accelerator.
