Why does the paint peel off on the surface of perforated aluminum panels? Delve into the common causes and explore effective solutions in this blog post.
Curtain wall aluminum panel is an environmentally friendly and energy-saving engineering material that has been vigorously developed and recommended by domestic regulatory authorities. It is mainly used in outdoor curtain walls and indoor ceilings.
Aluminum curtain wall panels have rich colors, are resistant to strong acids and alkalis, are resistant to corrosion, and have strong self-cleaning capabilities, making buildings with curtain wall aluminum panels durable. Some friends may ask why the paint on the aluminum curtain wall panels started to peel off after not being used for a long time. This is different from what we said. If you encounter this situation, you should pay attention. If you want to know more about the reason, please read the article below.
The reason why the finished curtain wall aluminum panels peel off is that I am sure people are familiar with the peeling paint. Moreover, after the paint peels off, the appearance is very ugly, and it is also harmful to the application. Therefore, when purchasing the finished curtain wall aluminum panels, , we must choose curtain wall aluminum panel products that meet the standards.

Regular maintenance and inspection can also help identify and address any potential issues before they worsen. Understanding these causes and taking appropriate preventive measures will ensure the longevity and aesthetics of perforated aluminum panels.
