Contract processing services for thin film coatings and gas plasma surface treatment offer a variety of beneficial features. Characteristics that can be achieved include lubricious, hydrophobic, and hydrophilic surfaces, while interface coatings for bonding like or different materials may be provided. Unlike conventional plasma surface treatments that often have shelf-life limitations, polymerized thin film coatings can provide permanent surface enhancement. Coating thickness is typically under a micron so even the most critical part tolerances are not affected. In the photo, a polypropylene part with a naturally hydrophobic (non-wetting) surface has been rendered hydrophilic by application of a polymerized thin film coating.
