What is NANO ACP? What is the fundamental difference between it and ordinary PVDF or PE coated ACP?

A: NANO ACP is a high-performance aluminum composite panel treated with nanotechnology on its surface. The key difference lies in the coating structure: ordinary coatings provide physical coverage, while the nano-coating forms a dense nano-scale network that alters surface properties at a molecular level, resulting in exceptional self-cleaning (lotus effect), anti-fouling, scratch resistance, and weatherability.
