Shanghai Paralon New Materials Company has developed an enhanced composite coating combining ALD inorganic coating and parylene organic coating through self-developed integrated machine equipment and special deposition methods. The new composite coating material has the protective advantages of ceramic films (such as alumina, titanium oxide, etc.) and aramid organic films, which can provide longer protection for equipment used in special environments (such as environments rich in water and oxygen), thereby extending its service life. Thanks to the atomic level thickness control and excellent shape retention performance of ALD process, the new composite coating can control the film thickness to a few microns while ensuring excellent protective performance. In addition, it can provide 360 ° all-round uniform coating for complex or micro components, thus protecting the product from corrosion.
