Technical applications might require a well defined glass surface structure. This could be a specific roughness, a number of surface elements, hills and valleys per Mikron, or a specific shape of those surface elements. The surface structure can for example make a plastic pen writing on glass feel similar to a pen writing on paper. Etched surfaces can offer optimized haptic properties, they can be less prone to fingerprints and other contaminations – ideal for touch applications, they can have adjusted friction for mechanical parts or they can have easy to clean properties.
To a large extent those properties can be combined. Glass whiteboards for example need an easy to clean surface. If they shall also be used as a beamer projection board, the surface also needs to fulfill light scattering demands. Whether as a beamer projection board or industrial displays from different sectors - the specific surface structures of our glasses support the function of many applications.
High-quality controls with touch function are increasingly common in modern computers and in telecommunications systems. They need to be non-reflective, resistant against mechanical wear or cleaning chemicals, sensitive to touch, feel comfortable and be easy to clean. Our etched glass meets those high demands - especially the anti-fingerprint effect, the mechanical and chemical resistance and the optimized haptic feeling represent major advantages compared to conventional anti-reflective coatings.
