Methyl ethyl ketone oxime is the organic compound with the formula C2H5C(NOH)CH3. This colorless liquid is the oxime derivative of methyl ethyl ketone. MEKO, as it is called in the paint industry, is used to suppress the "skinning" of paints: the formation of a skin on the paint before it is used.

Methyl ethyl ketone (MEK) is a solvent that is often used in the production of methyl ethyl ketone oxime (MEKO), as well as in other industrial applications. The process of producing MEKO involves the reaction of MEK with hydrogen peroxide and ammonia. The resulting product is then purified to obtain MEKO.
Methyl ethyl ketone oxime is composed of methyl ethyl ketone, hydroxylammonium phosphate, and other auxiliaries. Among them, MEK accounts for 72%, hydroxylammonium phosphate accounts for 24%, and auxiliaries account for 4%.
MEK is typically applied to MEKO in a manufacturing setting, where it may be used as a solvent or reactant in various industrial processes. MEKO is often used as an anti-skinning agent in paints and coatings, where it helps to prevent the formation of a film on the surface of the paint when it is exposed to air. It is also used as a cross-linking agent in some types of coatings, where it helps to improve the adhesion and durability of the coating.
In addition to its use in coatings and adhesives, MEKO is also used as a solvent in the production of certain types of plastics, as well as in the production of synthetic fibers and textiles. It can also be used as a stabilizer in some types of gasoline and diesel fuel. MEK and MEKO are both flammable and should be handled with care in a well-ventilated area with appropriate safety measures in place.
