Photocatalytically active coating for metals for
self-cleaning, air purification and germ prevention
nC® Nadicare® TA2203 Metal Surfaces is a very fine, water-based titanium-dioxide dispersion. Its formulation is a photocatalytically active coating and is fully transparent. Upon radiation with light, the coatings will release oxygen radicals from the ambient air and thus decompose organic pollution: The surface becomes self-cleaning. TA2203 is active under UV light and artificial light up to a wavelength of 475 nm.
TA2203 is designed for all uncoated metal surfaces (e.g. steel, stainless steel, aluminum, anodized aluminium and non-ferrous metals). Not suitable for painted, high gloss ﬁnished or powder-coated metal surfaces as well as for glass and non-metallic materials.
nC® Nadicare® TA2203 is an in- and outdoor application. Metal surfaces which are coated with TA2203 become self-cleaning and air purifying (reduction of VOC and bad odours).
Furthermore, the coating protects the surface against algae, mould, germs and bacteria. The design of nC® Nadicare® TA2203 provides self-cleaning properties to the treated surfaces, to protect them against pollution. The active self-cleaning titanium-dioxide particles transform all organic pollution on the surfaces, like soot, bird-droppings, stains of coffee, wine, oils, fingerprints etc. , into harmless compositions and oxygen. As the coating has strong hydrophilic capacities, pollution can never scale or “bake in.”
nC® Nadicare® TA2203 unites the advantages of photo catalysis and hydrophilicity. By doing this, the coating system offers a very robust and wear resistant surface. The lifetime cycle of the coating is around 10 years. The active self-cleaning characteristics of titanium-dioxide will easily remain intact throughout this period.
nC® Nadicare® TA2203 Metal Surfaces unites the advantages of photo catalysis with the unique capacity of nano-technology. Instead of sticking mechanically on the surface (like waxes or foils do), the use of nanotechnology ensures that the nC® Nadicare® TA2203 coating bonds into the surface chemically. The active self-cleaning characteristics of titanium-dioxide will not exhaust.
It is recommended to apply TA2203 with electrostatic spraying technique, alternatively with HVLP. Industrial application processes, especially coil coating, are also possible. In case of industrial application, technical consultation at the nC Group R&D dept. is strongly recommended.
As the technology is about bonding particles into surfaces, matrices of particles need to be built up after application. The treatment reaches full performance AFTER a cure time of approximately 3 to 72 hours, which is dependent upon environmental variables, humidity and heat applied (max 150 ⁰C. Tests for performance should be done after full cure. However, the surface can be used and exposed 10 to 30 minutes after application.
