Precision cleaning agents are used for cleaning printed circuit boards, metals and their components, LCD displays, precision cleaning (including electronic devices, optical components, aerospace, etc.), as temperature control fluids, leak detection, and as solvents

In January 2001, 3M Novec Low Surface Energy Film Coating EGC-1700 was launched for use in conjunction with 3M Novec HFE-7100DL electronic cleaning solution for controlling ions, metals, and non-volatile residues. 3M Novec EGC-1700 can be used as a protective coating for printed circuit boards (PWBs). After use, there is a very thin transparent film left on the surface of PWBs, which has excellent moisture-proof and anti stick effects. It is effective for various low surface tension liquids, such as oil stains, silicone oil, and anti photo corrosion solutions.

The concept of fluorine solvents

Perfluorous solvent, also known as fluorous solvent or perfluorocarbons, is an emerging green solvent that replaces all hydrogen atoms on carbon atoms with fluorine atoms in alkanes, ethers, and amines. The common ones include perfluoroalkanes, such as perfluorohexane, perfluorocyclohexane, perfluoromethylcyclohexane, perfluorotoluene, and perfluorohexane; Perfluorodialkylethers, such as perfluoro-2-butyl tetrahydrofuran, etc; Perfluorotrialkylamine, such as perfluorotrialkylamine, etc

Characteristics of fluorine solvents

Perfluorinated solvents have a higher density than ordinary organic solvents, a wider boiling range, and are high-density, colorless, non-toxic, and highly thermally stable liquids. They are characterized by low refractive index, low surface tension, and low dielectric constant. Perfluorinated solvents are excellent solvents for gases, capable of dissolving large amounts of hydrogen, oxygen, nitrogen, carbon dioxide, etc. However, their solubility is poor for ordinary organic solvents and organic compounds
