Toray Fingerprint Resistant Film For Smartphone and Tablet Touchscreens
Toray has developed a finger-print resistant film using a unique wet coating technology. Marks from fingers don't easily stick to this film, and even when they do, they're hard to see.
The new film has a uniform layer of oil-repellent material, with a randomly wrinkled nanometer structure on the surface. This makes the film more resistant to fingerprints than previous technologies, while maintaining high transparency and gloss.
"Previously, there were mainly two types of fingerprint-resistant technology - oil-attracting and oil-repelling types. But there's a trade-off with those, either a lot of finger grease sticks to the film, or the marks are highly visible. By contrast, the aim of Toray's technology is to provide the ultimate option, which is that not only do fewer fingerprints stick to the film, but they're also less noticeable."
"Let me explain using this acrylic panel with film on it. If you leave an oily fingerprint, it's like applying a stamp with oil. With previous films, the oil sticks fast. With this film, the fingerprint still leaves a trace, but it's very hard to see. That's a feature of the new film."
"We'd like this film to be used where it's important to prevent fingerprints, so for example, as a protective sheet for touchscreens, or a glossy decorative material. We're still at the R&D stage, so we'd like to get feedback from all kinds of users, to make this film even more effective."
