Fiberglass Supply Depot MEKP Peroxide Hardener is a premium Methyl Ethyl Ketone Peroxide (MEKP) catalyst formulated for use with polyester resins, vinyl ester resins, gelcoats, and tooling resins. It provides reliable, consistent curing performance, helping create strong, durable fiberglass laminates and professional-quality finishes.
MEKP is the industry-standard hardener for polyester and vinyl ester resin systems. When mixed at the manufacturer’s recommended catalyst ratio, it initiates the curing process, allowing resins and gelcoats to harden into tough, long-lasting composites. It is ideal for fiberglass layups, boat building, marine repairs, automotive restoration, mold making, and general composite fabrication.
Manufactured to meet demanding professional standards, this catalyst is suitable for both production environments and DIY fiberglass projects. It offers dependable performance when used with compatible resin systems and helps ensure predictable gel times and cure characteristics.
Always follow the resin or gelcoat manufacturer’s recommended catalyst percentages and safety guidelines. MEKP is a hazardous chemical and should be handled with appropriate personal protective equipment in a well-ventilated work area.
