The factors affecting the have light intensity and light time. In addition, the most important thing is the coating structure, including two aspects, one is the composition of the film and the two is the thickness of the coating.

For example, “smooth” is composed of a transition layer and a surface layer (self-cleaning layer), the transition layer can significantly improve the adhesion of the surface layer. Nano PVDF coated aluminium sheet coil thickness of the coating has a great influence on the self cleaning performance and adhesion: the coating is thin, the hydrophilicity of the coating is worse in the dark, the coating is thicker, the hydrophilicity of the coating is better and the ability of the dark hydrophilic retention is improved, and the coating is too thick and the adhesion is poor.

produced by Henan signi aluminum , suitable coating thickness and good hydrophilicity, can adapt to light time and light intensity, effectively obstruct the ultraviolet radiation directly on the curtain wall exposed in the sun, the billboard and other colored coatings, reduce its fading but not easy to age, and let the building. Things keep fresh and bright.
