Anti-fingerprint coatings

0

Anti-fingerprint coatings find application on stainless steel surfaces, plastics and glass. There is a high demand for clean surfaces presenting a perfect, hygienic optical appearance insensitive to fingerprints. These coatings are particularly suitable for designer surfaces in car interiors, households and buildings. Companies are focusing on high-performance surfaces for plastics and metals – a fast-growing market with strong margins and an annual volume of around EUR 800 million across Europe in 2010, and touch panels. There has been a sharp increase in the demand for touch panels used in a wide range of consumer products such as car navigation systems, smart phones and tablet PCS and the market has been expanding year by year. An important element for touch screens is an anti-fingerprint property in order to prevent deterioration and numerous lipophobic/lipophilic coating technologies have been proposed. Beyond the aesthetics, fingerprint smudges can interfere with actual viewing under conditions such as bright sunlight. This problem is more significant when multi-layer optical coatings are applied to the touch screens, usually to enhance high-ambient-light readability. Then, the presence of fingerprints can cause unattractive bluish smudges that can make the device almost unreadable. For military or medical applications, fingerprints that affect readability in high ambient light are a serious concern.

Structured stainless steel surfaces are used in the household such as housings, facings, decorative mouldings, grips, handles or faucets, general office items and especially decorative utilities and are especially sensitive to fingerprints. The cleaning requirements of stainless steel products are extensive. Anti-fingerprint nanocoatings reduce fingerprint to a minimum and can be simply wiped away with a dry cloth.  They facilitate cleaning glass doors, prevent limestone deposits in shower cabins and also offer long-term protection against glass corrosion. According to Toray Industries, if the technology can be widely commercialized, a market will be created on the scale of an annual coating area of 6,000,000 m2.
