MEKP (Methyl Ethyl Ketone Peroxide) and Cobalt are critical chemical components paired together to cure polyester and vinyl ester resins. MEKP acts as the catalyst (hardener), while Cobalt acts as an accelerator (promoter) to ensure the liquid resin transforms into a solid, durable plastic at room temperature.
How They Work Together
The Accelerator (Cobalt): Added directly to the liquid resin (often pre-mixed by the supplier), Cobalt kickstarts the chemical reaction.
The Catalyst (MEKP): MEKP is added last, right before you are ready to pour or laminate. When MEKP meets Cobalt, it triggers an exothermic (heat-releasing) chemical reaction that hardens the resin.
Mixing Ratio: Typically, MEKP is added at a strict ratio of 1% to 2% by weight of the resin. Using too little will leave the part sticky and uncured, while using too much makes the resin too brittle and causes it to shrink excessively.
