Photocatalytically active coating for plastics & paints
for self-cleaning, air purification and germ prevention
nC® Nadicare® TA2202 Plastic & Painted 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. TA2202 is active under UV light and artificial light up to a wavelength of 475 nm.
nC® Nadicare® TA2202 is an in- and outdoor application. The design of nC® Nadicare® TA2202 provides polycarbonate, polyester, PMMA, PVC, acrylic and HDPE surfaces, but also paints and powder coat surfaces with self-cleaning properties, 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® primers TP2221 (for rougher and absorbent surfaces) and TP2223 (for smooth, dense and non-absorbent surfaces) use the unique capacity of nano-technology to bond into surfaces and form a protective and active matrix. nC® Nadicare® TA2202 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 remain intact throughout this period.
nC® Nadicare® TA2202 Plastic & Painted 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® TA2202 coating bonds into the surface chemically. The active self-cleaning characteristics of titanium-dioxide will not exhaust.
It is recommended to apply TA2202 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 72 hours, which is dependent upon environmental variables, humidity and heat applied. Tests for performance should be done after full cure. However,
the surface can be used and exposed 60 minutes after application.
