Specialized Solvent for High-Purity Electronics Manufacturing: Electronic Grade N-Methyl-2-Pyrrolidone

Electronic grade N-Methyl-2-pyrrolidone (NMp) is a colorless, non-volatile liquid with a high boiling point and low vapor pressure. It is a powerful solvent with high solvency for resins and is miscible with water at all temperatures. NMp has a mild amine-like odor, and high chemical and thermal stability, and is used in the petrochemical, polymer, and battery industries.

NMp is used by semiconductor manufacturers as a wafer cleaner and photo-resist stripper. It is also used in the production of integrated circuits, other electronic components, wax removal, flux removal, burr removal, and cleaning electronic parts.

NMp is a member of the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide. It has a chemical formula of C5H9NO and is miscible with water and the most common organic solvents.

NMp requires adherence to specific safety protocols, including wearing appropriate personal protective equipment (PPE), including gloves, goggles, and protective clothing, to avoid skin and eye contact.

NMp is unlikely to cause liver or kidney damage if there is no noticeable effect on the nervous system. However, like other solvents, long-term exposure to NMp and drinking alcohol can increase your risk of liver damage.

The Role of Electronic Grade N-Methyl-2-Pyrrolidone Solvent in Electronics Manufacturing

N-Methyl-2-pyrrolidone (NMp) is a solvent used in many industries and applications, including electronics. It's a powerful, low-volatility solvent with high polarity and solvency power. NMp is used as a photoresist stripper, for refluxing, degreasing, and cleaning.

NMp is used in the electronics field because it can dissolve organic and inorganic compounds as well as or better than chlorofluorocarbon solvents. It's also replacing 1,1,1-trichloroethane in metal cleaning applications.

NMp is also used in:

  • paint and coating removal
  • petrochemical processing
  • Engineering plastics coatings
  • Agricultural chemicals
  • Industrial and domestic cleaning
  • pharmaceuticals

NMp is a water-miscible polar aprotic solvent. It's classified as a reproductive toxicant and can be absorbed into the body by inhalation, through the skin, and by ingestion.

NMp is colorless and transparent, but the color of the liquid can vary depending on the purity. It has a slight ammonia smell and is highly absorbent, so it will absorb moisture in the air.

NMp violently reacts with strong oxidizers such as hydrogen peroxide, nitric acid, and sulfuric acid. The primary decomposition products produce carbon monoxide and nitrogen oxide fumes. Excessive exposure or spillage should be avoided.

Yahtzee!

own nearly new running shoes that, as a result of shrinkflation? included foamy soles behind a thin rubber coating covering the plastic foundation. The fact that I wore them to the track meant that the bottoms had enough wear and tear to warrant replacement, but the tops were practically brand new, having only been worn maybe six times. It pulled off after I used another product. I took this and started dabbing at the soles, creating small spikes or spots with the tube. I didn't want to disturb them while I was working, so I let them dry for 48 hours, and the adherence is excellent! It feels like a fresh pair of running shoes and is quite grippy. I was slipping all over the asphalt and sidewalks, but now I can wear them TO the track, and they work fine on the rubberized track too. With this kind of use, one tube will last me for a very long time. Although I haven't used it for leaks or home repairs, I assume it will be useful in such situations as well. Thumbs up twice!

I tried resealing the aquarium instead of buying a new one when my turtle tank started to leak because the problem wasn't with the tank itself—rather, it was just a leaky seal. I'm glad I got two aquarium sealant tubes, and I found a youtube video that helped me with the procedure. The hardest and longest part of the operation was scraping off all of the old sealer. The sealant was easy to apply, but it needs to be done fast because it will solidify in a matter of minutes. I did this indoors because it's winter, so the vapors were intense. If at all feasible, try to operate in a ventilated space! This is a time-consuming technique that requires patience: scrape off the old sealant, wash, seal, let set, and then wash again. In the end, everything went well, and our turtle is swimming in his tank with happiness once more! Much less expensive than buying a brand-new aquarium!

My HVAC condensator leaked, which caused a terrible mess because it was below freezing for a spell. I bought this. When I used this, I was shocked to see that the leak seemed to be largely stopped. I turned off the equipment while the device was still in use and let it drain, albeit more slowly now that the silicone sealant was doing a decent job. I turned off the equipment and let it drain until it stopped, at which point I added more. As stated in the box, I let it stay for a full day. I went through the same procedure again because it spilled further up this time, applying it to any area that seemed suspect for a leak. Give it one more day to sit. After turning on the air conditioning, I noticed that there were no leaks left. I appreciate your amazing product and would use it once more as well as suggest it to others for leaks and other situations when a transparent sealant is required. Application Ease: Well, it was fairly simple, but since I'm absolutely not an expert at correcting things, it looked pretty bad. It didn't matter how it appeared, and I
