COPLAN - NOxOFF™ BITUME

NOxOFF™ BITUME is a nanostructured photocatalytic titanium dioxide (TiO₂) based active liquid with air purifying properties, ideal for the post-treatment of bituminous and slated membranes.‎ An environmentally friendly water-based product, whose active ingredient, activated by sunlight and/or UV light, degrades nitrogen oxides (NOx), sulphur oxides (SOx) and volatile organic compounds (VOCs) by transforming them into nitrates, which are then naturally washed away by rain.‎ Intended for application on bituminous and slated membranes, it is particularly suitable for urban areas with high population density and heavy traffic.‎ NOxOFF™ BITUME 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™ BITUME is one of the most studied and applied technologies for "active" building materials against urban pollution.‎ Application: NOxOFF™ BITUME is intended for bituminous and slated membranes for outdoor use.‎ 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.‎ Surfaces must be dry and clean.‎ NOxOFF™ BITUME is ready to use, but for spray applications a wetting agent must be added.‎ Carry out a test application on a small area to check for any undesirable reactions.‎ Then apply NOxOFF™ BITUME by spraying or impregnation.‎ Surface drying: approx.‎ 1-3 hours; complete drying/full activation: 12-24 hours.‎ 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™ BITUME COPLAN
