N-Ethyl-2-Pyrrolidone (NEP, CAS 2687-91-4), min. 99.5%, supplied wholesale by Zyntex. Polar aprotic solvent for PU dispersions, wire enamels, cleaners and agrochemical formulations. CoA and SDS with every lot.
N-Ethyl-2-pyrrolidone (C6H11NO) is a colorless to pale yellow liquid that boils at about 212°C. It mixes completely with water and most organic solvents and dissolves many polymers and resins.
Coating producers use NEP as a coalescing and processing solvent in polyurethane dispersions, wire enamels and polyamide-imide coatings. It also appears in paint strippers, industrial cleaners, agrochemical formulations and electronics processing. For a long time it was promoted as a replacement for N-methyl-2-pyrrolidone (NMP).
However, NEP is itself classified in the EU as toxic for reproduction, like NMP and Dimethyl Formamide. Users therefore need to apply the same strict exposure controls. Where possible, formulators evaluate alternatives such as Dimethyl carbonate or Acetonitrile for their process.
