Anti-fingerprint stainless steel refers to the stainless steel coated with a transparent colorless or light yellow nano-metal polymer composite coating, which firmly together with stainless steel surface after drying to form a transparent solid protective film coting. Fingerprint-resistant process originated in Japan to meet the needs of household appliances production, it increases the appearance of metal plate and prevent people from touching the surface of these plates to leave fingerprints, oil, sweat, dust and so on to make it lose luster.
Anti-fingerprint treatment is not that the fingerprint will not be printed on the surface of the stainless steel, but the fingerprint trace is lighter than ordinary stainless steel and relatively easy to handle and will not remain stains. Generally it is obtained after grinding, drawing, polishing, mirror, titanium/copper plating and other processing for thestainless steel plate and coil.
The effect of anti-fingerprint depends on the thickness of the coating. The thicker the coating, the better the anti-fingerprint effect of stainless steel. But too thick coating will be formed orange dermatoid grain in the stainless steel surface which affect the appearance. Generally speaking, the greater the surface tension, the easier it is to adhere to other objects, anti-fingerprint treatment is to reduce the tension of the metal surface through the coating. The composite coating is 1-10 microns thick and contains silicon dioxide, which can change the original reflectivity and high scattering characteristics of stainless steel.
The advantages of anti-fingerprint processing
Good appearance: Anti- fingerprint stainless steel has super resistant to fingerprints and anti-pollution performance. It’s not easy to adhere to fingerprints, dust and other pollutants, Stainless steel with a better surface than ordinary metal coating, which retains the metallic texture well, prolongs the service life of furniture and reduces routine maintenance.
High hardness: These anti-fingerprints hydrophobic coating has a very good hardness, which can protect the metal surface not easily scratch, peeling and turning yellow.
Excellent anti-rust ability: Stainless steel without fingerprints has excellent anti-rust performance, can effectively prevent the outside erosion, greatly extend the service life of home appliance.
Fingerprint-free stainless steel plate has been widely used in elevators, security doors, car interiors, hotel decoration, home appliances, aerospace equipment, medical equipment, lighting, furniture and so on. The test found that there was a big difference between the anti-fingerprint part and the non-anti-fingerprint part in the protection against the same external contamination for the same stainless steel plates/sheet and former usage time is much longer than latter.
