Physical form:Liquid
Chemical name:Methyl ethyl ketone peroxide, in solvent mixture
Applications:Trigonox® V328 is a methyl ethyl ketone peroxide (MEKP) for the cure of unsaturated polyester resins in the presence of a cobalt accelerator at ambient and elevated temperatures.The curing system Trigonox® V328/cobalt accelerator is developed for general purpose GRP- and non GRP-applications. Examples: the curing of laminating resins and castings. Practical experience throughout many years has proven that for marine applications a special MEKP with low water content and without polar components is demanded in order to prevent from osmosis and other problems. Butanox M-50 is the MEKP preferred and advised for these kind of applications.For room temperature application it is necessary to use Trigonox® V328 together with a cobalt accelerator (e.g. Accelerator NL-49P) to obtain a proper reactivity.
