Nano self-cleaning
Color coated aluminum coil
Struggling with dust accumulation on building facades and the high cost of high-altitude cleaning? The nano self-cleaning coated aluminum coil is here—based on premium aluminum substrates and equipped with nano-level self-cleaning coatings, it integrates self-cleaning, weather resistance, and corrosion resistance, effectively addressing the pain points of traditional building materials such as rapid fading and high maintenance costs. It has become the preferred material for applications like curtain walls and roofing.
Unveiling the Principle of Nanoscale Self-Cleaning
The core of nano self-cleaning color coated aluminum coils is the perfect combination of nano level self-cleaning coatings in the coating and aluminum coil roll coating technology, thereby achieving the effect of "automatic rainwater cleaning".
After high-temperature roller coating, the nano scale self-cleaning coating is evenly distributed on the surface of the aluminum coil, forming a dense cross-linked coating structure. When rainwater falls on the surface of the coating, it does not condense into water droplets, but quickly spreads into a uniform water film. The water film will carry pollutants such as dust and oil, and naturally slide down along the slope of the board without residue or scaling.
Nano scale self-cleaning coatings have super hydrophilic properties, and the surface of aluminum coils is smoother. The water film formed by water droplets can take away dust and stains from the source, without leaving water stains and causing secondary pollution.
All performance is equally hardcore
The nano self-cleaning color coated aluminum coil not only "self-cleaning", but also has solid and excellent performance in other aspects. The roller coating process and the selection of high-quality coatings make its weather resistance, coating performance and other indicators far exceed industry standards.
| Performance dimension | Key metrics | Practical value |
| Self cleaning performance | Carbon black experiment Δ E ＜ 2; Water contact angle ≥ 30 °; Self cleaning rate after aging ≥ 90% | After being washed away by rainwater, the appearance looks like new and does not require frequent manual cleaning |
| Weather resistance | QUV-A shows no abnormalities after 3000 hours of UV aging; Salt spray test for 1000 hours meets the standard | UV resistant, corrosion-resistant, suitable for complex environments such as coastal areas and humidity |
| Coating performance | Film thickness ≥ 25 μ m; T-bend ≤ 2T; MEK scratch resistance ≥ 100 times | Bending and stamping without paint peeling or cracking, suitable for complex architectural shapes |
| Color retention | Color difference Δ E ≤ 1.5 | Long term use without yellowing or fading, long-lasting appearance |
Whether it is high-end venues or residential buildings, nano self-cleaning color coated aluminum coils can create a "self-cleaning" exterior wall for buildings, bidding farewell to the trouble of frequent cleaning and allowing every building to maintain cleanliness and beauty for a long time.
Litong Aluminum Industry not only has nano self-cleaning color coated aluminum coils, but also has many different functions to adapt to different scenarios of color coated aluminum coils. Choose aluminum for the exterior wall decoration material scheme of the building!
