Methyl Ethyl Ketone Peroxide (MEKP) Supplier Malaysia
- Also known as
- MEKP
- 2-Butanone Peroxide
Methyl ethyl ketone peroxide (MEKP) is an organic peroxide initiator used mainly to cure unsaturated polyester resins. ChemTrade handles Malaysian enquiries for MEKP formulations used in fibreglass, composite, casting and laminating operations.
Commercial MEKP is supplied as a liquid formulation rather than one universal neat specification. Active oxygen, diluent, water content and reactivity can differ, so the resin system and current specification should be supplied when requesting a quotation.
The product is often called an MEKP catalyst in the composites trade, although it functions as a curing initiator. It is entirely different from methyl ethyl ketone solvent, benzoyl peroxide, dicumyl peroxide and tert-butyl peroxybenzoate.
Send the required formulation or reactivity profile, resin application, quantity and delivery location with your enquiry. Availability, packing and documentation are confirmed with the quotation.
- Grade
- industrial, composites
- Appearance
- clear to pale liquid formulation, composition dependent

Common questions about methyl ethyl ketone peroxide
What is methyl ethyl ketone peroxide used for?
MEKP is used mainly as an initiator for curing unsaturated polyester resins in fibreglass, composite, casting and laminating processes.
Is MEKP the same as methyl ethyl ketone?
No. MEKP is an organic peroxide formulation, while methyl ethyl ketone or MEK is a solvent. They must not be substituted.
Are all MEKP formulations interchangeable?
No. Active oxygen, diluent, water content and reactivity profile can differ, so the current resin-system specification should be supplied.
What does MEKP catalyst mean?
The trade commonly calls MEKP a catalyst, but in polyester curing it functions as an initiator. The exact formulation still needs to match the process.
Can packing and documents be confirmed?
Yes. State the required documents and preferred pack. Options are confirmed for the quoted formulation.
What information is needed for a quote?
Send the resin system, formulation or reactivity requirement, quantity, delivery location and any current SDS or specification.
