Methyl Ethyl Ketone Peroxide(MEKP) CAS 1338-23-4

Methyl ethyl ketone peroxide (MEKP) is an organic peroxide, often existing in the form of dimethyl phthalate solution. It is a room temperature curing agent and initiator for unsaturated polyester resins, commonly known as "white water". It has the characteristics of a colorless, transparent, oily liquid and needs to be used in conjunction with accelerators (such as cobalt salts). It is widely used in fiberglass, artificial agate and other fields.

Product Advantage

• High-efficiency initiator: MEKP is one of the most.

• Excellent curing characteristics: Fast curing speed, moderate exothermic reaction, providing good mechanical properties and chemical resistance.

• Wide range of applications: Widely used for curing unsaturated polyester resins (fiberglass products, artificial stone, gelcoat), and can also be used as an initiator for other resin systems.

• Formulation flexibility: Can be used in combination with accelerators (such as cobalt salts) to form systems, adjust curing speed, and adapt to different temperatures and processes (such as hand lay-up, spraying, pultrusion, compression molding).

• Enhanced safety: Modern products improve storage and use safety and reduce flammability and explosion risks through optimized formulations (such as reducing active oxygen content and adding stabilizers).

Technical Parameters

Product Uses

Methyl ethyl ketone peroxide (MEKP) is primarily used as a room-temperature curing agent and initiator for unsaturated polyester resins. It is widely applied in fiberglass products, artificial agate, buttons, and casting. It also serves as an initiator in organic synthesis, playing a crucial role in composite material manufacturing, coatings, and adhesives industries. It promotes resin cross-linking and curing at room temperature.

Specific applications include:

• Fiberglass (FRP) products: boats, pipes, storage tanks, automotive parts, building materials, etc.

• Artificial stone: production of artificial agate and artificial marble.

• Handicrafts and decorations: buttons, castings, model making, etc.

• Coatings and adhesives: as a curing catalyst in certain systems.

• Organic synthesis: as a free radical initiator in polymerization reactions.

Product Operate Guide

• MEKP is typically used in conjunction with accelerators (such as cobalt salts).

• At room temperature, methyl ethyl ketone peroxide decomposes to generate free radicals, which initiate cross-linking polymerization of unsaturated polyester resin, causing it to change from a liquid to a solid state.

• This product is the most commonly used curing agent for unsaturated polyesters, mainly used for the curing of unsaturated polyesters at room and medium temperatures. It is usually used in conjunction with cobalt-based accelerators.
