PVDF cover
This type of coating is a type of resin that increases the resistance of composite sheets against UV rays and alkaline and acidic conditions due to the presence of fluorine element and polymer layer in it.
Nano-PDF cover
Nano-PDF coating is implemented in such a way that in addition to the PVDF coating, another layer is placed on it, which is slightly different from the PVDF layer in terms of molecular structure.
Polyester layer
This type of coating puts a layer of polyester on the aluminum sheets. One of the disadvantages of this type of coating is its lack of resistance against acid rain and adverse weather conditions, and its use on the exterior of the building is not recommended.
