MEKP Catalyst for polyester and vinylester resin and gelcoat systems including our GP Polyester Resin, Clear Polyester resin, ISO Polyester resin. Methyl Ethyl Ketone Peroxide (MEKP) is a chemical compound commonly used as a catalyst in the polymerization of unsaturated polyester resins and in other processes where controlled curing or hardening is required. It is an organic peroxide, and its main use is to initiate the crosslinking reaction in the production of fiberglass-reinforced plastics. Here’s a detailed description of MEKP: Chemical Composition: MEKP is an organic peroxide with the chemical formula C8H10O4. It is typically a colorless liquid but can have a slight yellowish tint depending on purity and storage conditions. Function: MEKP is primarily used as a curing agent (initiator) for polyester and vinyl ester resins. It decomposes at elevated temperatures, releasing free radicals that initiate the polymerization (crosslinking) of the resin, turning it from a liquid into a solid. This is a crucial process for materials used in automotive, boat-building, and construction industries. Physical Properties: MEKP is typically stored in stable concentrations (usually 9-10% solution in a stabilizer such as water or other chemicals). It has a boiling point around 90°C (194°F) and a melting point of -20°C (-4°F). It is highly reactive, especially when exposed to heat, friction, or contamination, and must be handled with caution. Applications: Polyester Resin Curing: MEKP is widely used in the production of fiberglass composites, where it acts as the initiator for the curing of polyester resins. Plastics and Coatings: MEKP is used in the production of various plastics and coatings requiring the polymerization of resins. Adhesives: MEKP is also used as a curing agent in some adhesive formulations, especially those involving unsaturated polyester resins.
