Basics and Characteristics of Representative Organic Solvents for Industrial Use │ IPA (Isopropyl Alcohol)

■ Introduction

IPA (Isopropyl Alcohol) is one of the most widely used organic solvents in industrial applications. It has a strong track record, particularly in cleaning and degreasing electronic components and precision equipment, and is adopted in many manufacturing sites as a versatile solvent with an excellent balance of cost and performance.

On the other hand, as it is flammable and subject to organic solvent regulations, safety measures and legal compliance are essential.
