Physical performance of the metal surface covered with the highly durable and chemically adsorbed fluorocarbon film

In this study, the physical performance (adhesion resistance, heat resistance, rubbing resistance, chemical resistance) of an extremely thin and the high durable and chemically adsorbed fluorocarbon film with a low surface energy on the metal surface (the thickness is about 1 nm order) was evaluated.The demolding resistance in injection-molding can decrease without compromising the mold shape and dimensional accuracy by using a chemically adsorbed and highly durable fluorocarbon film.Consequently, this technique should be very beneficial when applied to the molding of resin materials that have difficulty with mold release, such as silicone, urethane and elastomer resins. Further, this method will be useful for the molds used for making precision components that need to be highly accurate and ultra thin, such as optical components and chemical chips, for which conventional release agents cannot be used.
