NANO-PRODUCTS and NANO-COLORS In “nano-thin” layers Attophotonics creates a wide range of colors without the need for chemical pigments. Due to their particular nanostructure the layers selectively reflect a specific spectral sub-fraction whereas other electromagnetic waves are absorbed efficiently. Thus, the surface shines, dependent on the viewing angle, in a well defined color. The same principle gives rise to the sparkling colors of the wings of some butterflies. KEY PROPERTIES OF ATTOPHOTONICS’ NANO-COLORS A wide spectrum of colors can be printed or applied directly onto arbitrary surfaces with the same chemistry (several options available) efficiently using materials. The coatings create a modern, metallic look are color-fast, extremely heat stable (600°C) if required and machine-readable. They show characteristic absorption in the visible as well as in the IR- and UV-light spectrum. They can be used for colored bar-codes and anti-counterfeiting tags. Glitter-effects and color gradients can also be created. The potential applications of this innovative new technology range from novel surface design and POC-diagnostics to intelligent packaging for quality control of food products. APPLICATION Depending on material, desired additional properties and required resistance to mechanical stress, Attophotonics’ nano-colors can be applied in various ways: direct coating glitter films, stickers/ tags APPLICATION of Attophotonics’ nano-colors and Attophotonics’ smart colors By means of a combination of different coating technologies the nano-color can be created directly on the material (metal, glass, plastics,…). on Aluminium, Silver, Rhodium,….. On Brushed Stainless Steel NANO-COLOR GLITTER The glitter material consists of coated platelets (available in various sizes and thicknesses e.g. mesh sizes: 150-600 µm and 0.6 - 2 mm with 4 µm thickness). It can be applied directly onto adhesive surfaces or as glitter varnish. The 3D-tipping and sparkle of the glitter supplement the basic properties of the nano-colors. Glitter Color Spectrum NANO-COLOR FOIL/ NANO-COLOR TAGS Plastic films coated with Attophotonics’ nano-colors are available as sheets and can be cut and applied with ease. On request, Attophotonics also provides nano-color-stickers with arbitrary form and size.
