COPLAN - NOxOFF™ DRY

NOxOFF™ DRY is an active liquid product based on nanostructured photocatalytic titanium dioxide (TiO₂) with air-purifying properties.‎ The active ingredient, activated by sunlight and/or UV light, degrades nitrogen oxides (NOx), sulphur oxides (SOx) and volatile organic compounds (VOCs) into nitrates, which are then naturally washed away by rain.‎ Intended for application on concrete surfaces, it must be applied by coating onto concrete elements after curing.‎ NOxOFF™ DRY is completely invisible and does not alter the aesthetic appearance of the substrate.‎ The photocatalytic effect is permanent and not subject to exhaustion due to consumption of the active ingredient.‎ NOxOFF™ DRY is one of the most studied and applied technologies for "active" building materials against urban pollution.‎ Application: NOxOFF™ DRY is intended for concrete products for outdoor use and is particularly suitable for urban contexts characterised by high population density and intense vehicular traffic.‎ The product is activated by exposure to sunlight and/or UV light.‎ The greater the irradiation and the larger the treated surface area, the greater the overall air purification effect.‎ Application must take place on concrete elements after curing.‎ Concrete elements must be dry, clean and free of dust.‎ NOxOFF™ DRY is ready to use for spray application on hardened concrete.‎ Application with hydraulic spray nozzles with droplet size ≤ 200 μm.‎ Minimum application temperature: +5 °C.‎ The product completes the curing phase in the first 24 hours, during which no water should be applied to the element.‎ In the case of prefabricated elements, the surface must be dry (approx.‎ 1 hour) before handling or stacking.‎ The equipment can simply be cleaned with water immediately after use.‎ NOxOFF™ is an innovative photocatalytic treatment for concrete or asphalt surfaces, designed to actively reduce air pollutants.‎ Thanks to TiO₂-based technology, the system contributes to the degradation of NOx, SOx, and volatile organic compounds, improving air quality and providing surfaces with permanent self-cleaning properties.‎ A sustainable, high-performance solution for road infrastructure and urban areas.‎ The use of the system can contribute to the achievement of LEED credits and support interventions compliant with the Minimum Environmental Criteria (CAM), being consistent with the required sustainability and innovation objectives.‎ Further info from manufacturer on NOxOFF™ DRY COPLAN
