METHYL ETHYL KETONE PEROXIDE is a strong oxidizing agent. May be ignited by heat, sparks or flame and undergoes self-accelerating decomposition. Explosive decomposition occurs at 230° F. Sensitive to sunlight. Ignition and/or explosion may occur if mixed with readily oxidizable materials.
2-Butanone peroxide technical Synonym: Ethyl methyl ketone peroxide, Methyl ethyl ketone peroxide CAS Number 1338-23-4. Linear Formula C 2 H 5 C(OOH)(CH 3)OOC(OOH)(CH 3)C 2 H 5. Molecular Weight 210.22 . Beilstein/REAXYS Number 1759757 . MDL number MFCD00042641. PubChem Substance ID 24845732
It has been reported that MEKP might be the explosive that was to be used in the alleged 2006 transatlantic aircraft plot to destroy planes flying from the United Kingdom to the United States. Acetone peroxide, TATP, is another reported possibility.
Sources of ignition, such as smoking and open flames are prohibited where methyl ethyl ketone peroxide is used, handled, or stored in a manner that could create a potential fire or explosion hazard. Wherever methyl ethyl ketone peroxide is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.
Methyl Ethyl Ketone Peroxide (MEKP) is used as a hardener in manufacture of resins, synthetic rubber and other petrochemical plastics. It is an ingredient of paints, varnishes and paint removers. MEKP is also used in fiberglass and plastics industry as a curing agent. It is an organic peroxide, which is explosive in its pure form.
Liquid causes eye burn. Vapor irritates eyes, nose, and throat; can cause headache, dizziness, nausea, weakness, and loss of consciousness. METHYL ETHYL KETONE is explosive in the form of vapor when exposed to heat, flame or sparks. Ignition on contact with potassium tert-butoxide.

Methyl ethyl ketone peroxide, also known as 2-butanone peroxide, is a strongly oxidizing (caustic) organic peroxide that is commonly used in the manufacture of acrylic resins and as a room temperature hardening and curing agent for fiberglass-reinforced plastics and unsaturated polyester resins (HCN, 2002; NTP, 1993).
It is also known as 2-Butanone or Butan-2-one. It is used for solvent extraction of many metals as it complexes with MEK.
Methyl ethyl ketone peroxide. For this application, MEKP is dissolved in dimethyl phthalate, cyclohexane peroxide, or diallyl phthalate to reduce sensitivity to shock. Benzoyl peroxide can be used for the same purpose. MEKP is a severe skin irritant and can cause progressive corrosive damage or blindness.
Methyl Isopropyl Ketone or 3-Methyl-2-butanone is a colorless liquid with a sweet acetone like smell. It is highly flammable. Methyl Isopropyl Ketone is stable, does not polymerize and is highly compatible with a variety of organic reagents.
Other uses. Butanone is the precursor to methyl ethyl ketone peroxide, which is a catalyst for some polymerization reactions such as crosslinking of unsaturated polyester resins. Dimethylglyoxime can be prepared from butanone first by reaction with ethyl nitrite to give diacetyl monoxime followed by conversion to the dioxime: In...
Laboratory Chemical Safety Summary (LCSS) METHYL ETHYL KETONE PEROXIDE is a colorless liquid. Strong irritant to skin and tissue. Used as an initiator for room temperature cure of unsaturated polyester resins.
For example, methyl ethyl ketone peroxide and cyclohexanone peroxide may explode if they are mixed with acetone, a common solvent. Using reclaimed solvents of uncertain composition can also be hazardous. They may contain dangerous concentrations of contaminants that are incompatible with the organic peroxide.
METHYL ETHYL KETONE PEROXIDE: METHOD 3508, Issue 2, dated 15 August 1994 - Page 4 of 5 After 4 hrs at 1 L/min airflow through impingers containing MEKP standards in DMP, less than 10% of the MEKP carried over from the front to the backup bubbler.
For large scale use of this product: use non-sparking ventilation systems, approved explosion-proof equipment and intrinsically safe electrical systems in areas where this product is used and stored. What Personal Protective Equipment (PPE) is needed when working with methyl ethyl ketone?
MEPOXE (Methyl Ethyl Ketone Peroxide) MEPOXE is a catalyst which contains Methyl Ethyl Ketone Peroxide. MEPOXE is a hardener of unsaturated polyester resins that can be used for: • Making several kinds of FRP (Tanks, Fishing Boat, Bath Tub, Cooling Tower etc.) • Coating on Plywood • Button • Coating on the surface of iron, furniture etc.
About methyl ethyl ketone peroxide (MEKP) MEKP is a catalyst used in the composites industry for polyester and vinyl ester resins. It reacts with the resin to turn it from a liquid to a solid (cure it). MEKP is an organic peroxide.
MEKP Hardener. (methyl ethyl ketone peroxide) Catalyst for our polyester resins and gelcoats. Resins are sold with enough catalyst to achieve 1.25% and gelcoats sold with 2%. Extra catalyst is needed in cooler temperatures or for faster drying times.
(organic compound) methyl ethyl ketone (surfing) The chemical methyl ethyl ketone peroxide which is used as a catalyst to harden the fibreglass resin in surfboard manufacture and repair. Strictly speaking the abbreviation would be MEKP, but the shorthand MEK is frequently found.
Methyl Ethyl Ketone (MEK) MEK also is used as an extraction medium for fats, oils, waxes and resins. It is a highly efficient and versatile solvent for surface coatings. Because of its effectiveness as a solvent, MEK is especially valuable in formulating high solids coatings, which help to reduce emissions from coating operations.
