## Features

- ✅ Role of Catalyst: In composites, a catalyst is used to initiate and accelerate the curing or hardening of the resin system. MEKP is a free radical initiator that triggers the polymerization reaction in polyester and vinyl ester resins, leading to the formation of a solid and durable composite material.
- ✅ Mixing with Resin: MEKP is typically mixed with the resin system just before application. The ratio of MEKP to resin is carefully controlled to achieve the desired curing characteristics and processing time. The specific ratio and mixing instructions may vary depending on the resin manufacturer's recommendations.
- ✅ Curing Process: Once MEKP is mixed with the resin, a chemical reaction starts that causes the resin to crosslink and solidify. The curing process can be accelerated by applying heat, which helps to speed up the reaction and shorten the overall curing time.
- ✅ Shelf Life: MEKP has a limited shelf life and can degrade over time, affecting its effectiveness as a catalyst. It is important to use fresh MEKP to ensure reliable curing performance.
