1-methyl-2-pyrrolidone (NMP) Instruction:

NMP, also known as 1-methyl-2-pyrrolidone or N-Methylpyrrolidone, is a solvent used in a range of products. The average consumer is most likely to encounter NMP in paint strippers, although safer alternatives exist. NMP has been strongly associated with developmental effects, including abortion.

The U.S. Environmental Protection Agency (EPA) describes NMP as a developmental toxicant. in 2017, the EPA proposed banning the chemical for paint stripping, but later shelved the proposal under pressure from industry and formally withdrew NMP in 2021. We are calling on retailers to take action and stop selling paint strippers containing NMPs. In the meantime, if you need to remove paint or coatings, make sure to avoid NMP and other toxic chemicals such as methylene chloride.

1-methyl-2-pyrrolidone (NMP) Description：

NMP (1-methyl-2-pyrrolidone) is a polar solvent with excellent performance. Since NMP has very high solubility and high boiling point and low freezing point, NMP is easy to use and has a wide range of applications.

1-methyl-2-pyrrolidone (NMP) Features:

NMP is a nitrogen-containing five-membered heterocyclic compound with a wide range of applications due to its excellent properties as follows：

1. High polarity, completely miscible in most organic solvents (alcohols, ethers, ketones, aromatics, chlorinated hydrocarbons, etc.), and high solubility for organic and inorganic substances.
2. NMP can be miscible with water in any proportion.
3. Higher flash point than other similar solvents.
4. High boiling point, low freezing point, easy to use.
5. Good chemical stability and thermal stability, non-corrosive.
