Autotex Steel is a hard-coated polyester film for producing stainless-steel effects on membrane switches, keypads, and fascia panels. The tough outer surface offers excellent resistance to abrasion and a wide range of chemicals and solvents. The film is manufactured using a conventional flexible polyester substrate. The hardcoat layer has a textured finish which, when the film is printed on the reverse side with standard chrome, metallic, or silver inks, creates the appearance of a brushed stainless steel or other metallic looks. In addition to producing a high quality appearance, this method provides a significant weight advantage over metal parts, and, unlike stainless steel, Autotex Steel does not show fingerprints, and can easily be printed with clear display windows or contain secret-until-lit graphics. The film can be easily embossed, making it ideal for use with domed tactile membrane keypads or in applications where keys or panel areas require raised edges. Embossed areas have an excellent flex modulus, with a typical flex life for domed keys being in excess of 5 million actuations.
