Catalyst M is a general purpose MEKP for curing unsaturated polyester (UP) resins at room temperature. Generally used together with metal salts as accelerators. Suitable for the curing of gelcoat resins, laminating (coating), vinylester, fiber, button, dope and casting type polyester resins as well as GRP applications. Particularly suitable for gelcoat applications with proven low water content. (E.g. Pipe production, marine applications, cabinet production etc.)

A single MEKP initiator formulation cannot provide optimum results in all resin systems. Evaluation of each MEKP in each resin intended for use is absolutely essential before full-scale manufacturing is attempted.
