Ketone Peroxides

Ketone Peroxides, represented by MEKP (Methyl Ethyl Ketone Peroxide), are essential room-temperature curing initiators for unsaturated polyester resins. They rapidly initiate resin cross-linking at ambient temperatures and are widely used in the production of Fiberglass Reinforced Plastic (FRP), composites, artificial stone, and gel coats. With stable activity and compatibility with various resin systems, they are a key component in hand lay-up, spray-up, and other molding processes.

Ketone Peroxides
Product Detail

Ketone Peroxides are a crucial class of organic peroxide curing agents that initiate the cross-linking reaction of unsaturated polyester and vinyl ester resins by releasing free radicals, making them essential for room-temperature curing in composite manufacturing. Represented by Methyl Ethyl Ketone Peroxide (MEKP), this product series is widely trusted in industries such as Fiberglass Reinforced Plastic (FRP), artificial stone, and coatings for its high efficiency and reliable performance.

We offer a comprehensive range of ketone peroxides designed for both general and specialized curing applications:
