Polyvinylidene Fluoride (PVDF) coatings are factory-applied resin-based coating systems typically embedded with colored pigment particles to support a variety of matte finish colors. They are most commonly used in architectural coating applications due to their excellent resistance to weathering by sunlight, moisture or temperature.

Color-coated aluminum (color-coated aluminum coil), common polyester color-coated aluminum (color-coated aluminum coil), is widely used in aluminum honeycomb panels, aluminum ceilings, roof surfaces, scraps, and its performance is very stable and not easily corroded.

Phosphating is a commonly used pretreatment technology. In principle, it should belong to chemical conversion film treatment. It is mainly used for phosphating on the surface of steel, and non-ferrous metals (such as aluminum and zinc) can also be phosphating.

Anodic oxidation: on the surface of aluminum, a layer of alumina would be produced through electrochemical principle. This oxide film has special properties.

Aluminum plated films are usually used on packages with barrier or light shielding requirements. Therefore, the thickness, surface condition and adhesion fastness of the aluminum plated layer will directly affect the above properties.

Aluminum vapor deposition equipmentAt present, the vacuum aluminum plating equipment used for plastic film in the market mainly has two types: winding type and suspension type.
