Methyl Ethyl Ketone also called Butanone, ethyl methyl ketone, or methyl acetone is a colourless fairly volatile liquid with a pleasant pungent odour.

MEK is a liquid solvent used in surface coatings, adhesives, printing inks, chemical intermediates, magnetic tapes and lube oil dewaxing agents. 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.  MEK is a natural component of many foods, including apple juice, beans, chicken, honey and a variety of cheeses.
