Butanox® HBO-50 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/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.



True high-gloss paste wax.
Withstands high-temperature exothermic reactions of resins and does multiple releases easily.
Contains carnauba wax, synthetic waxes and high-temperature resistant resins for effective multiple releases of plastic parts through numerous cycles.
