New Surface Treatment for Aluminum Cladding: Nano Self-Cleaning Coating Implemented

May 4, 2026 – We officially announce that our new generation nano self-cleaning coating technology is fully implemented in our aluminum cladding panel series. This innovative surface treatment technology brings revolutionary self-cleaning and anti-pollution performance to building facade aluminum cladding, greatly reducing the manual maintenance cost of building facades, especially for high-rise buildings and landmark projects in harsh environments.

As a professional aluminum cladding manufacturer, we have been focusing on the technological innovation of building facade materials. The traditional aluminum cladding surface is easy to adhere to dust, industrial pollution, and bird droppings, which requires regular manual cleaning, especially for high-rise buildings, which has high cleaning costs and safety risks. Our new nano self-cleaning coating adopts the latest super-hydrophobic nano technology, which forms a dense protective layer on the surface of the aluminum cladding, realizing the "lotus leaf effect" self-cleaning function.

Core Performance Advantages of the Nano Self-Cleaning Coating

1. Super-Hydrophobic Self-Cleaning Function: The nano coating forms a micro-nano rough structure on the surface of the aluminum cladding, with a water contact angle of more than 110°, showing excellent super-hydrophobic performance. Rainwater will form spherical water droplets on the surface, roll off quickly, and take away dust, dirt, and pollutants on the surface at the same time, realizing automatic cleaning of the facade without manual cleaning.
2. Excellent Anti-Pollution & Anti-Corrosion Performance: The dense nano protective layer completely isolates the aluminum substrate from the external environment, effectively preventing acid rain, industrial pollution, salt spray, and other corrosive substances from eroding the panel. It can resist the adhesion of oil stains, bird droppings, and graffiti, and the pollutants can be easily washed away by rainwater, keeping the facade clean and bright for a long time.
3. Enhanced Weather & UV Resistance: The nano coating is added with high-performance UV stabilizers, which can effectively resist UV radiation, prevent coating fading and chalking, and maintain color stability for more than 20 years in outdoor harsh environments. It has passed QUV 5000-hour weather resistance test and ASTM B117 3000-hour salt spray test, fully adapting to coastal, industrial, and high-altitude harsh environments.
4. Compatible with Original Production Process & Environmental Protection: The nano self-cleaning coating is fully compatible with our existing PVDF fluorocarbon coating production line, no need to change the production process, and maintains the excellent mechanical properties and fire resistance of the aluminum cladding. The coating uses water-based environmental protection formula, zero-VOC emission, fully complies with EU environmental protection standards, and is non-toxic and harmless to the environment and human body.
5. Cost-Effective & Long Service Life: The nano self-cleaning coating greatly reduces the frequency and cost of manual facade cleaning. For high-rise buildings, the cleaning cost can be reduced by more than 80% during the service life, and the service life of the aluminum cladding is extended by more than 30%, which has a very high cost performance for the whole life cycle of the building.

Application Scenarios

Our aluminum cladding with nano self-cleaning coating is ideal for: high-rise office buildings, commercial complexes, hotel facades, airport terminals, railway stations, stadiums, coastal buildings, industrial zone factory buildings, and other projects that are difficult to clean manually and have high requirements for facade cleanliness and durability.
