    Butanox® HBO-50 VRB is a methyl ethyl ketone peroxide (MEKP) for the curing of unsaturated polyester resins in the presence of a cobalt accelerator at room and elevated temperatures. The curing system Butanox® HBO-50 VRB/cobalt accelerator is particularly suitable for the curing of laminating resins and lacquers when a faster gelation and initial cure speed is required than can be obtained with Butanox® M-50. Moreover the manufacture of light resistant parts may be possible contrary to the curing benzoyl peroxide/amine accelerator. The vanishing red (VR) series of products include a red indicator system that disappears during the cure. The red color is only visible when needed but not in the finished end product. The key features are: indicates initiator presence, monitoring of the mixing step, monitoring of the cure by color and indicating under-cured area's in the mold, and last but not least it leaves the end product colorless after the cure.
