Methyl ethyl ketone peroxide (MEKP) is a powerful organic peroxide widely used as a catalyst and curing agent in the production of polyester resins and fiberglass-reinforced plastics. It acts as a strong oxidizer that initiates the hardening or polymerization process of resins, making it essential in manufacturing composite materials like boat hulls, automotive parts, and construction panels. Due to its reactive and potentially hazardous nature, MEKP is handled with care under strict safety protocols.

Industrial Uses

1. Performance Chemicals

Polymerization Catalyst: MEKP is widely used as a free-radical initiator in the polymerization of unsaturated polyester resins (UPRs), crucial for producing fiberglass-reinforced plastics (FRPs).
Cross-Linking Agent: Acts as a catalyst in curing thermosetting resins and other polymer systems.

2. Construction

Fiberglass Construction Materials: MEKP is used in the curing of resins that form components such as fiberglass panels, roofing sheets, water tanks, and decorative fixtures.
Concrete Repair Kits: Used in some polymer concrete formulations and repair kits for rapid hardening.

3. Paints, Coating & Adhesives

Curing Agent for Adhesives: MEKP is used in two-component adhesive systems, especially those based on polyester or vinyl ester resins, enabling strong and durable bonds.
Laminating Adhesives: Plays a critical role in curing adhesives used in lamination and composite material bonding.
