N-Methyl-2-Pyrrolidone, an Integral Part of the Electronics and Automotive Sectors
N-Methyl-2-Pyrrolidone is a chemical compound with an excellent solvency and high boiling point for a wide range of organic and inorganic chemical compounds. Moreover, N-Methyl-2-Pyrrolidone has high chemical and thermal stability, making it ideal for use in engineering polymers and coating resins application. N-Methyl-2-Pyrrolidone is also used as paint and cleaning agent (stripping solvent) due to its low surface tension. Furthermore, it can be used in the synthesis and formulation of various paints and coatings, polymers, and electronic products.
Wire wrappers, agrochemicals, and petrochemical are some of
the other applications of N-Methyl-2-Pyrrolidone. The demand for
N-methyl-2-pyrrolidone is increasing rapidly due to the implementation of
stringent regulations on fossil fuel-based vehicles. Moreover, the demand for
N-methyl-2-pyrrolidone is expected to increase with the increasing sales of
electric vehicles. According to the International Energy Agency (IEA), sales of
electric cars topped 2.1 million globally in 2019, surpassing 2018, to boost
the stock to 7.2 million electric cars.
The United States-based automaker, Ford Motor plans to
invest US$ 11 billion in electric vehicles by 2022 and have 40 hybrid and fully
electric vehicles in its model lineup. Electrodes of li-ion batteries are
mainly produced by mixing a conductive material, active lithium-ion, along with
N-Methyl-2-pyrrolidone and polyvinylidene fluoride. Moreover, in the
electronics sector, N-methyl-2-pyrrolidone is used as a solvent in the
manufacturing of polyurethane coatings, epoxy, polyimide/polyamide wire
enamels, and flexible polyimide copper clad board.
Photoresists are used in the production of micro
electromechanical systems, magnetic recording heads, flat panel liquid crystal
displays, printed circuit boards, printing plates, and integrated circuit
devices, such as computer memory chips and microprocessors. Other applications
of N-methyl-2-pyrrolidone, in the electronics sector, include removing excess
rumble at the time of production of various electronic parts. However, N-methyl-2-pyrrolidone
is banned in Europe, the European Commission has added N-methyl-2-pyrrolidone
to REACH Annex XVII, the restricted substances list.
