Benefits and Applications

Electronics

N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP has been used in the electronics industry for many years as a photoresist stripper. Now, with the phase out of CFC’s, N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP has gained widespread acceptance as a solvent in other electronic applications including semi-aqueous defluxing, degreasing, and coatings (polyamide, epoxy and polyurethane).

Graffiti Removers

N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP -based graffiti removers combine high performance and biodegradability with low volatility and low flammability. N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP can be blended with glycol ethers or acetates such as Arcosolv PMA, Arcosolv DPMA; they are cost effective and improve performance on surfaces defaced by lipstick and crayon graffiti.

Agricultural

The agricultural chemical industry takes advantage of NMP’s solvency and handling properties in agricultural formulations.

Pharmaceuticals

N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP is used as a solvent in pharmaceutical synthetic procedure because of its broad solvency. One potential use for N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP is as a dermal penetration enhancer for pharmaceuticals.

Consumer and Industrial Cleaners

N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP is an effective stripping agent used in floor stripping, poven cleaners, graffiti removers, and paint strippers. Due to its high solvency and low volatility, it is used in automotive and industrial cleaners with solvents such as hydrocarbons, terpenes, Arconate Propylene Carbonate and P-Series glycol ethers. 

Coatings Solvent

N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP is a powerful solvent for most commercial resins. Due to its high boiling point and excellent solvent power, N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP extends and improves the properties of high temperature bake coatings. For instance, high solid binders are more easily obtained with N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP as the solvent. Quite often, baked finishes yield coatings with outstanding mechanical and dielectric properties. N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP also aids rheological control: better flow and leveling -less cratering and pinholing. For these reasons, N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP has been shown to be highly effective in wire coating and other high temperature coating applications. N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP is also the preferred solvent for urethane dispersions and is an excellent coalescent for acrylic and styrene acrylic latexes.

Petrochemical Processing

N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP has been shown to have a selective affinity for unsaturated hydrocarbons, aromatics and sulfur-bearing gases. Due to its relative non-reactivity and high solvency, N-Methyl-2-Pyrrolidone / N-Methyl Pyrrolidone / NMP finds wide applicability as an extraction solvent in lube oil processing as well as in natural and synthetic gas purification's.

Miscellaneous Solvent Applications
