Case 1: Electronics Component Cleaning

A leading electronics manufacturing company was facing issues with the cleaning of its high - density PCBs. The traditional cleaning solvents were not able to effectively remove the stubborn fluxes and contaminants, resulting in a high rate of product defects. After switching to N - Ethyl - 2 - pyrrolidone, the company noticed a significant improvement in the cleaning quality. The PCBs were thoroughly cleaned, and the defect rate was reduced from 15% to less than 5%. The use of N - Ethyl - 2 - pyrrolidone also led to a decrease in the cleaning time, increasing the overall production efficiency.

Case 2: Coating Formulation

A coating manufacturer was developing a new type of high - performance coating for automotive applications. They needed a solvent that could improve the coating's flow and adhesion properties. By incorporating N - Ethyl - 2 - pyrrolid
