Chemical Filming is a very common and inexpensive finish, used by several industries for various products and purposes. The chemical in question is a sealant, which adheres to and alters the exterior of a metal part, creating a thin film of material that provides corrosion protection for metal parts. In many cases, this chemical film coating is the final step in the production process, but it’s also common to find chemical film coatings used to prime the surface of a product for paint application.
Chemical film coating, also called chemical conversion coating, results in a variety of finishes and colors, varying from clear and iridescent colors to blue, green, gold and even black. In general, the darker the color, the stronger the chemical film coating and the more resistance it will present to corrosive forces, though there are some exceptions.
In addition to color, chemical films vary according to their composition and purpose. To categorize chemical films, most companies defer to the military’s MIL-DTL-5541F specification. This specification organizes chemical films into the following categories:
