Six Major Uses of Silver Nitrate Powder

  In the production of modern high-performance coatings and inks, NMP (N-Methyl-2-pyrrolidone ， cas ： 872-50-4 )  plays an irreplaceable role as an efficient solvent. With its excellent solvency, good chemical stability, and moderate evaporation rate, NMP is widely used in demanding coating and ink systems. This article provides a detailed overview of the main applications, benefits, and future trends of NMP in this industry. 1. Basic Characteristics of NMP NMP is a highly polar, high-boiling (202°C), low-volatility organic solvent with excellent solvency. It can dissolve a wide range of natural and synthetic polymers such as polyurethane, epoxy resin, and acrylic resin. Its transparency and low odor also make it suitable for indoor applications. 2. Applications in Coatings In the coatings industry, NMP is primarily used as a solvent for base materials like polyurethane and epoxy resins. It is particularly suitable for industrial anti-corrosion coatings, automotive coatings, c...

1. Introduction NMP (N-Methyl-Pyrrolidone, CAS: 872-50-4)  is a highly polar, low-volatility organic solvent known for its excellent solubility, chemical stability, and low toxicity. It is widely used across various industries. In the pharmaceutical and agrochemical fields, NMP plays a crucial role as a key solvent. In our previous discussions, we introduced the applications of NMP in lithium batteries and the semiconductor electronics industry. Now, let’s explore how NMP is widely used in pharmaceutical and pesticide synthesis due to its superior solubility, high boiling point, and low evaporation loss, making it a preferred solvent for many pharmaceutical and agrochemical manufacturers. 2. Applications of NMP in the Pharmaceutical Industry In the pharmaceutical industry, NMP is mainly used in drug synthesis, solvent extraction, drug dissolution, and formulation processing. 2.1 Key Solvent in Drug Synthesis As a highly polar solvent, NMP enhances the solubility of poorly soluble d...

  I. Introduction N-Methyl-Pyrrolidone (NMP)   is a product with a wide range of applications. In the previous issue, we discussed its use in the lithium battery industry. This issue will focus on its applications in the semiconductor and electronics industry. II. Main Applications of NMP in the Semiconductor and Electronics Industry 1. Wafer Cleaning with NMP During semiconductor manufacturing, organic contaminants and fine dust easily adhere to the wafer surface. Due to its excellent solubility, NMP can effectively remove grease, flux residues, and metal ions from the wafer surface, ensuring cleanliness and improving chip yield. 2. Photoresist Stripping Photoresist is a key material in semiconductor manufacturing, but after exposure and etching, the remaining photoresist must be completely removed. NMP efficiently dissolves photoresist without damaging the silicon wafer surface, making it widely used in wet photoresist stripping processes. 3. Electronic-Grade High-Purit...
