Sumitomo 3M Co., Ltd. recently introduced a fluorine coating that can form a 1μm coating at room temperature. This coating is mainly used for the coating of precision mechanical parts on high-density integrated circuit substrates.

In recent years, due to the miniaturization and the development of high-density integration of electronic component substrates, a very small amount of water or oil will affect the reliability of products. Therefore, these products are in great need of micro-coatings that are resistant to water, oil, and corrosion. coating. Sumitomo 3M's fluorine-based polymer coating can be coated on a substrate to form a very thin, low surface tension coating at room temperature, with excellent water and oil repellency and good anti-fouling effect.
