The main application for methyl-ethyl ketone (MEK) is as a low-boiling solvent for nitrocellulose, acrylic and vinyl surface coatings. About 63% of global MEK demand is derived from the paints and coatings industry. Its advantage is that low viscosity solutions can be obtained, having a high solids content, without affecting the film properties. The lacquers are used in the automotive, electrical goods and furniture industries.
MEK can also be used in rubber-based industrial cements and printing inks. Its fast evaporation rate makes it popular for rubber-based industrial cements, low-temperature bonding agents and as an azeotropic separation solvent for printing inks. It is also a component of the solvent system used in producing magnetic tape. Demand for adhesives and video tape applications is increasing.
In addition, MEK is a solvent required for the polymerisation processing of polystyrene, acrylonitrile-butadiene-styrene, and styrene-butadiene-rubber while a derivative, methyl ethyl ketone peroxide, is used as a hardening agent in reinforced polyester fibre glass manufacture.
MEK irritates the eyes and throat leading to coughing, headaches and nausea. It is highly flammable.
ICIS pricing quotes MEK in Europe, Asia-Pacific and the USA.
