Methylethyl ketone oxime MEKO is the organic compound with the formula C2H5C(NOH)CH3. This colourless liquid is the oxime derivative of methyl ethyl ketone. MEKO, as it is called in the paint industry, is used to suppress “skinning” of paints: the formation of a skin on paint before it is used. MEKO functions by binding the drying agents, metal salts that catalyze the oxidative crosslinking of drying oils. Once the paint is applied to a surface, MEKO evaporates, thereby allowing the drying process to proceed. Other antiskinning agents have been used, including phenol-based antioxidants, but these tend to yellow the paint.[1] Butanone oxime is also used in some types of RTV silicones.
Methyl Ethyl Ketoxime (MEKO)
Product Stewardship Summary December 2007
Chemical Name: Methyl ethyl ketoxime
Synonyms: 2-Butoxime; 2-Butanonoxim; Methyl ethyl ketone oxime; Ethyl methyl
ketoxime; MEK-oxime; MEKO
CAS Number: 96-29-7
CAS Name: 2-Butanone oxime
EC (EINECS) Number: 202-496-6
• Methyl ethyl ketoxime (MEKO) is an essential chemical used as an anti-skinning agent in paints
and lacquers, as a blocking-agent for isocyanate in polyurethanes, and in the manufacture of
oxime silanes (that are used as crosslinkers for silicone sealants).
• MEKO is a High Production Volume (HPV) chemical produced at over 1,000,000 pounds
annually. Honeywell, as a member of a consortium, has sponsored MEKO under EPA’s HPV
Challenge program and the Organisation for Economic Co-operation and Development’s HPV
Programme.
• Honeywell has established a provisional occupational exposure limit of 3 ppm (10 mg/m3
) for
an 8-hour time-weighted average and a short-term exposure limit of 10 ppm for use in worksite
safety programs.
• MEKO is a clear, colorless combustible liquid.
• MEKO is severely irritating to eyes. If it gets into the eyes, immediately flush with plenty of
water and seek medical attention to avoid serious damage. MEKO is moderately toxic in the
unlikely event of ingestion. Ingesting or breathing high concentrations may cause harmful, but
reversible, effects on the blood (anemia) and inhalation can irritate nasal passages. MEKO is
slightly irritating to skin, and can be absorbed through the skin to cause harmful effects on the
blood and nervous system. Getting MEKO on the skin may cause an allergic response in
certain individuals.
• MEKO is rapidly metabolized and eliminated from the body. MEKO does not cause harmful
effects on reproduction or development.
• Male rodents developed liver tumors when repeatedly exposed during their lifetime to high
concentrations of MEKO. These tumors developed late in life and did not affect survival.
MEKO is not genotoxic, pointing to a threshold mechanism for cancer development (i.e., a
“safe level” below which cancer will not occur, a level well above typical exposures).
Therefore the human risk of cancer is low.
MEKO has low toxicity to aquatic organisms, upon either single or repeated exposure.
• MEKO has minimal potential to accumulate in the bodies of humans or animals. It is readily
biodegradable and will not persist in the environment.

• Le méthyléthylcétoxime (MEKO) est un produit chimique essentiel utilisé comme agent anti-peau dans les peintures
et les laques, comme agent de blocage pour l’isocyanate dans les polyuréthanes, et dans la fabrication de
oxime silanes (qui sont utilisés comme agents de réticulation pour les mastics silicones).
• MEKO est un produit chimique à haut volume de production (HPV) produit à plus de 1 000 000 livres
annuellement. Honeywell, en tant que membre d’un consortium, a parrainé MEKO sous HPV de l’EPA
Challenge et le VPH de l’Organisation de coopération et de développement économiques
Programme.
• Honeywell a établi une limite d’exposition professionnelle provisoire de 3 ppm (10 mg / m3
) pour
une moyenne pondérée sur 8 heures et une limite d’exposition à court terme de 10 ppm pour une utilisation en chantier
programmes de sécurité.
• MEKO est un liquide combustible clair et incolore.
• MEKO est très irritant pour les yeux. En cas de contact avec les yeux, rincer immédiatement et abondamment
de l’eau et consultez un médecin pour éviter des dommages graves. MEKO est modérément toxique dans le
événement improbable d’ingestion. L’ingestion ou la respiration de concentrations élevées peut être nocive, mais
réversibles, les effets sur le sang (anémie) et l’inhalation peuvent irriter les voies nasales. MEKO est
légèrement irritant pour la peau et peut être absorbé par la peau pour provoquer des effets nocifs sur le
sang et système nerveux. L’administration de MEKO sur la peau peut provoquer une réaction allergique
certains individus.
• MEKO est rapidement métabolisé et éliminé de l’organisme. MEKO ne cause aucun
effets sur la reproduction ou le développement.
• Les rongeurs mâles ont développé des tumeurs hépatiques lorsqu’ils ont été exposés à plusieurs reprises au cours de leur vie à
concentrations de MEKO. Ces tumeurs se sont développées tard dans la vie et n’ont pas affecté la survie.
MEKO n’est pas génotoxique, ce qui indique un mécanisme de seuil pour le développement du cancer (c.-à-d.
«Niveau de sécurité» en dessous duquel le cancer ne se produira pas, un niveau bien supérieur aux expositions typiques).
Par conséquent, le risque humain de cancer est faible.
MEKO a une faible toxicité pour les organismes aquatiques, lors d’une exposition unique ou répétée.
• MEKO a un potentiel minimal d’accumulation dans le corps des humains ou des animaux. C’est facilement
biodégradable et ne persistera pas dans l’environnement.
Le méthyléthylcétone oxime est le composé organique de formule C 2 H 5 C (NOH) CH 3 . Ce liquide incolore est le dérivé oxime de la méthyléthylcétone . MEKO, comme on l’appelle dans l’industrie de la peinture, est utilisé pour supprimer le “pelage” des peintures: la formation d’une peau sur la peinture avant son utilisation. MEKO fonctionne en liant les agents de séchage , des sels métalliques qui catalysent la réticulation oxydante des huiles de séchage . Une fois la peinture appliquée sur une surface, MEKO s’évapore, permettant ainsi au processus de séchage de se poursuivre. D’autres agents anti-peau ont été utilisés, y compris à base de phénolantioxydants , mais ceux-ci ont tendance à jaunir la peinture. [1] Le butanone-oxime est également utilisé dans certains types de silicones RTV.
