A: We provide the following assurances: 1) Third-party test reports: Available for key properties like weatherability (QUV), anti-fouling (e.g., contact angle test showing >110°), and chemical resistance. 2) On-site demonstration: The lotus effect can be easily demonstrated with a simple “water droplet test.” 3) Warranty: We offer a longer warranty period for NANO ACP compared to standard panels, explicitly covering the coating performance.
