MEKP Hardener

DD-MP1 is a medium-reactive standard MEKP hardener in dimethyl phthalate, which is suitable for various of our polyester resins as well as our styrene-free Diepal-S systems. Whether it is a Diepal laminating resin, SG gelcoat, PHD adhesive resin DP, or a topcoat Diepal, our DD-MEKP hardener is used in every resin system. For our polyester resin systems, a hardener addition of 1.3-2.4% is typically recommended.
