※ have all the advantages of fluorocarbon coating. At the same time, the surface layer in the baking fluorocarbon bake on dense again at the nano level, oil or dust adhesion to the surface of aluminum plate, because the Nano is very dense surface, the stains can not penetrate to the elements inside, so when the rain will wash time With the rain falling natural. Fluorocarbon and the surface is a gully-like molecular structure, so when the stains adhere to the surface, tiny molecules to penetrate into its elements in space, to use neutral chemical cleaning detergent, Adsorption can be a stain. Using nano-aluminum plate will go a long way to reduce the latter part of the building cleaning maintenance costs.
