metyylietyyliketoni

Metyylietyyliketoni, also known as butanone or MEK, is an organic compound with the chemical formula CH3COCH2CH3. It is a colorless, volatile liquid with a sharp, sweet odor reminiscent of acetone. MEK is a ketone and is miscible with most organic solvents, as well as water.

MEK is widely used as a solvent in various industrial applications. It is particularly effective at dissolving resins, lacquers, adhesives, and coatings. Its rapid evaporation rate makes it a common choice for paints, varnishes, and printing inks. MEK is also employed in the manufacturing of plastics, synthetic rubber, and textiles. In some cases, it can be found in nail polish removers and glues.

From a safety perspective, MEK is flammable and its vapors can form explosive mixtures with air. It is an irritant to the eyes, skin, and respiratory system. Prolonged or repeated exposure can lead to dermatitis and central nervous system effects. Appropriate ventilation and personal protective equipment are necessary when handling MEK. It is important to store MEK in a well-ventilated area away from heat and ignition sources.
